The Ultimate Guide

A complete English grammar reference — written for real learners.

Six master sections covering every rule our AI checks, with clear explanations, examples, and the exact mistakes Indian English speakers make most often. Bookmark this page — you'll come back to it.

1 Subject–Verb Agreement 2 The Twelve Tenses 3 Articles: A, An, The 4 Prepositions 5 Active vs. Passive Voice 6 Punctuation Rules

1 Subject–Verb Agreement

Subject–verb agreement is the single most common grammar error we see in the AI Grammar Checker. The rule itself is simple: a singular subject takes a singular verb, and a plural subject takes a plural verb. The complexity comes from the exceptions, the intervening phrases, and the deceptive nouns that look plural but aren't.

In everyday Indian English, the most frequent slip is dropping the -s from a third-person singular verb in the present tense: "She go to the market" instead of "She goes to the market." This happens because Hindi and many other Indian languages don't add an ending to the verb for he/she/it — the verb stays the same for all persons. But English demands the extra -s for a very specific reason: without it, the reader cannot tell whether the subject is singular or plural, and the sentence loses its subject–verb signal.

The base rule with examples

✗She go to college every day.
✓She goes to college every day.
✗The team are winning the match.
✓The team is winning the match. (American English — a team acts as one unit)
✗One of my friend is moving to Canada.
✓One of my friends is moving to Canada. ("one" is the subject → singular verb, but "friends" must be plural)

When the subject is separated from the verb

The trickiest cases happen when a prepositional phrase sits between the subject and the verb. Readers (and writers) often match the verb to the nearest noun instead of the actual subject.

  • "The list of items is on the desk." — The subject is "list" (singular), not "items."
  • "A box of chocolates was delivered yesterday." — Subject: "box."
  • "Each of the students has a book." — "Each" is always singular.

Indefinite pronouns

Indefinite pronouns like everyone, everybody, someone, anybody, nobody, each, neither, either are grammatically singular, even when they refer to multiple people. This trips up almost every learner at some point.

✗Everybody know that the earth is round.
✓Everybody knows that the earth is round.
✗Neither of the options look appealing.
✓Neither of the options looks appealing.
Quick tip: When a sentence feels wrong but you can't see why, remove every phrase between the subject and the verb, then read it aloud. "One of my friends is moving" becomes "One is moving" — the verb matches instantly.

2 The Twelve Tenses (and When to Use Them)

English has twelve tenses, not three. Yes, really. The confusion isn't with the concept — Hindi, Marathi, and most Indian languages express past, present, and future with layers of aspect too — the confusion is with the labels and the exact situations where each one fits. This section walks through all twelve with plain-English explanations and examples.

Present tenses

Present Simple — facts, habits, routines. "I drink tea every morning."

Present Continuous — something happening right now, or an ongoing temporary situation. "She is studying for her exam." Learners often overuse this where simple present is correct: "I am understanding what you mean" should be "I understand what you mean" because understanding is a state, not an action in progress.

Present Perfect — an action completed in the past with relevance to now. "I have finished my homework." Not to be confused with past simple. If you say "I finished my homework," you're just stating a fact about the past. If you say "I have finished my homework," you're implying "so I'm free now."

Present Perfect Continuous — an action that started in the past and is still ongoing. "I have been waiting for you since morning." This is the correct form for the classic Indian-English error "I am waiting for you since morning." The word since almost always demands present perfect continuous, not present continuous.

Past tenses

Past Simple — a finished action at a known past time. "Yesterday, I saw him at the store." Note that "Yesterday, I seen him" is wrong twice over — seen is a past participle and needs have before it.

Past Continuous — an ongoing action in the past, often interrupted. "We were walking down the street when it started raining." The classic error "We was walking" comes from treating we as singular. Always plural: we were, you were, they were.

Past Perfect — an action completed before another past action. "By the time he arrived, I had eaten my lunch." The word had is essential — without it, both actions sound simultaneous. Learners often use simple past here: "I ate my lunch before he arrived" is technically acceptable but loses the time-depth that past perfect provides.

Past Perfect Continuous — an action that had been ongoing up to a past moment. "She had been working there for five years before she resigned."

Future tenses

Future Simple — a plan, prediction, or spontaneous decision. "I will call you tomorrow." Note that the correct form is "I will graduate next year," not "I will have graduate from college." The -ed ending never attaches to a modal verb.

Future Continuous — an action that will be in progress at a future time. "This time next week, I will be flying to Delhi."

Future Perfect — an action that will be completed before a future moment. "By next year, I will have graduated from college." This is the correct form for the sentence most learners get wrong: will have + past participle, not will have + base verb.

Future Perfect Continuous — an action that will have been ongoing up to a future point. "By December, I will have been working here for three years."

How to practise: Write one sentence per tense about your own daily life — your morning routine, your job, your weekend plans. Ten sentences a day for two weeks will permanently wire these forms into your speech.

3 Articles: A, An, The

Articles are the smallest words in English and the biggest source of frustration for learners whose native language doesn't have them. Hindi, for example, uses ek for "one/a" and doesn't require any article at all in most sentences. English, unfortunately, insists on them.

When to use "a"

Use a before a singular countable noun that begins with a consonant sound and is being mentioned for the first time or is one of many.

  • "I saw a dog in the park." (any dog, one of many)
  • "She is a doctor." (one of many doctors)
  • "Can I have a cup of tea?" (any cup, not a specific one)

When to use "an"

Use an before a singular countable noun that begins with a vowel sound — not necessarily a vowel letter.

  • "She is an engineer."
  • "He waited for an hour." (the h in "hour" is silent)
  • "That's an honest mistake." (the h in "honest" is silent)
✗He is a honest man.
✓He is an honest man.
✗I need an advice.
✓I need some advice. (advice is uncountable)

When to use "the"

Use the when the noun is specific, already known to the reader, or unique. This is the article learners miss most often — and its absence is what makes Indian English sound "off" to native ears.

  • Specific: "Please close the door." (the one we both see)
  • Already mentioned: "I bought a book. The book was expensive."
  • Unique: "The sun rises in the east." (there's only one sun)
  • Superlatives: "He is the tallest in the class."
✗I am going to market.
✓I am going to the market.
✗The Paris is a beautiful city.
✓Paris is a beautiful city. (no article before most city names)

4 Prepositions: The Small Words That Change Everything

English prepositions are notorious. There's no logical system — "in the morning" but "at night," "on the bus" but "in a car," "good at English" but "interested in maths." The only way to master them is exposure and repetition. This guide covers the ones that cause the most errors in Indian English.

In, on, at (place)

Use in for enclosed spaces (in the room, in Delhi), on for surfaces (on the table, on the wall), and at for specific points (at the bus stop, at the door).

✗The book is in the table.
✓The book is on the table.

In, on, at (time)

Use in for months, years, seasons (in May, in 2025, in winter), on for days and dates (on Monday, on 5th June), and at for specific clock times (at 4 PM, at noon).

✗Let's meet on next Monday.
✓Let's meet next Monday. (no preposition before "next")

Common preposition traps

  • "Good at English" — never "good in English."
  • "Married to" — never "married with."
  • "Discuss the topic" — no preposition. Never "discuss about."
  • "Reach the office" — no preposition. Never "reach to."
  • "Similar to" — never "similar with."
  • "Suffer from" — never "suffer with."
  • "Listen to music" — never "listen music."
  • "Afraid of" — never "afraid from."
Practical strategy: Don't memorise lists. Read English newspapers out loud for ten minutes a day. Prepositions have a "sound" — after a few months of exposure, wrong prepositions will feel wrong.

5 Active vs. Passive Voice

Every English sentence has a voice. In active voice, the subject performs the action. In passive voice, the subject receives the action. The AI Grammar Checker flags passive voice not because it's wrong, but because writers overuse it — and passive voice is almost always weaker, vaguer, and less direct.

The formula

Active: Subject + verb + object → "The chef cooked the meal."
Passive: Object + be + past participle + (by subject) → "The meal was cooked by the chef."

✗Mistakes were made by the team. (passive — hides who did what)
✓The team made mistakes. (active — clear and direct)

When passive is actually the right choice

  • When the doer is unknown or unimportant: "The window was broken last night."
  • In scientific writing where the process matters more than the person: "The solution was heated to 80°C."
  • In formal announcements: "The results will be published tomorrow."
  • To emphasise the receiver of the action: "The President was awarded the prize."

Why this matters for IELTS and job applications

IELTS Writing Task 2 examiners reward active voice in argumentative essays. Passive voice dilutes your opinion, weakens your claims, and adds unnecessary word count — all three of which lower your band score. In cover letters and resumes, "I led a team of eight" beats "A team of eight was led by me" every time.

6 Punctuation Rules That Change Meaning

Punctuation isn't decoration — it's grammar. The comma placement in "Let's eat, grandma" vs. "Let's eat grandma" completely changes the meaning. Here are the rules that matter most, and the errors our AI catches most often.

The period (full stop)

Ends a declarative sentence. In British and American English, a period goes inside quotation marks when quoting speech: He said, "I will come." Also, use periods in abbreviations that end a sentence (etc., i.e.) but never double them: not "He left.."

The comma

  • Separating items in a list: "I bought apples, oranges, and grapes."
  • After introductory phrases: "After the meeting, we went home."
  • Before coordinating conjunctions joining independent clauses: "I wanted to go, but I was tired."
  • Around non-essential info: "My brother, who lives in Delhi, is visiting." (extra info)

Never join two independent clauses with only a comma. That's a "comma splice" — a serious error the AI Grammar Checker will flag: "I finished work, I went home" should be "I finished work, and I went home" or "I finished work. I went home."

The semicolon

Joins two closely related independent clauses without a conjunction. "I have a big test tomorrow; I can't go out tonight." Use it sparingly — it's a sign of sophisticated writing.

The colon

Introduces a list, a quotation, or an explanation. "She had one goal: to win." Never use a colon after a verb or preposition unless the list follows directly.

The apostrophe

Marks possession (Rahul's book) or contraction (don't, it's). The single most common error is confusing its (possessive) with it's (it is). "Its raining" is wrong — always "It's raining." The second-most common is writing "1980's" instead of "1980s" for decades.

Quotation marks

Use double quotation marks for direct speech in American English, single for British. Punctuation goes inside in both. For quotes within quotes, alternate: "She said, 'I'll be there.'"

The one test that works: Read your sentence aloud. If you would naturally pause, a comma belongs there. If you wouldn't pause, it probably doesn't. The AI Grammar Checker has this logic built in.
Inside the AI

How the AI Learns Your Tone — and Why It Matters

Grammar is only half the story. The right word in the wrong tone can ruin an interview or a business email. Here's how our AI reads the invisible signals in your writing.

💼

Professional / Corporate

Direct, courteous, action-oriented. Common in emails, proposals, reports, and LinkedIn messages. Short sentences, active voice, clear requests.

Best for: Job applications, client emails, internal reports
Signals: Active verbs, no slang, polite requests
💬

Casual / Conversational

Relaxed, personal, contraction-heavy. Common in WhatsApp messages, personal blogs, social media captions, and messages to friends.

Best for: Friends, family, social posts
Signals: Contractions, phrasal verbs, short sentences
🎓

Academic / Formal

Precise, structured, evidence-based. Common in IELTS essays, university assignments, research papers, and thesis writing.

Best for: IELTS, TOEFL, PTE, university work
Signals: Complex sentences, hedged claims, formal vocabulary

Reading Between the Lines: What "Tone" Actually Means

When a language model "reads" your text, it's not just checking whether the verbs agree with the subjects. It's building a multi-dimensional picture of how your writing feels — and then comparing that picture against the tone you're likely aiming for. At Paramarsh Education, we've tuned our AI Grammar Checker to output three specific tone signals for every piece of text: tone, readability, and formality.

The tone field tells you what emotional register your writing carries. If you write "Hey, quick q — can you send that file?" the AI labels it Casual. If you write "Dear Sir, I am writing to request the file," it labels it Formal. This matters enormously because the same message needs different tones for different audiences — and learners whose native language has a different formality system often struggle to hit the right register in English.

The readability field measures how easy your text is to process for an average reader. A sentence like "The committee has reached a final consensus" reads as Moderate. A sentence like "The group decided" reads as Easy. Long, complex sentences with multiple subordinate clauses push readability toward Complex. IELTS examiners reward varied sentence length but penalise anything that becomes hard to follow — the readability score tells you exactly where you sit.

The formality field captures the grammatical signals of register: contractions (don't, can't, it's), phrasal verbs (put off, look into), slang (gonna, kinda), and direct address ("you"). If your cover letter contains "I'm gonna", the AI will flag it and suggest "I will" or "I am going to."

Why this matters for IELTS vs. Corporate Writing

IELTS Academic Writing Task 2 expects a band 7+ essay to sit at Formal tone with Moderate readability. It cannot be too simple (band 5-6 territory) and it cannot be so complex that the examiner loses the argument. Our AI tells you precisely which direction to adjust.

Corporate writing has a different target. Emails should read as Professional tone with Easy readability. Executives read hundreds of emails a day — long, flowery sentences get ignored. Short, action-oriented sentences get replies. Our AI pushes you toward that clarity.

Marketing and content writing has yet another target: Conversational tone with Easy readability. It should sound like a friend explaining something, not a lecture. When you paste your blog draft, the AI will tell you if you've slipped into academic mode.

Building a Tone Diary

We recommend an exercise to every serious learner: once a week, paste three versions of the same paragraph into the AI Grammar Checker. Write one version for a friend, one for your boss, and one for an IELTS examiner. Compare the tone and formality outputs side by side. Within a month, you'll start instinctively "hearing" your own writing from the reader's perspective — which is the single biggest leap any learner can make.

Tone is invisible until it's wrong. Our AI makes it visible.

Real Results

Three students. Three habits. One tool.

Every learner has a signature error — the mistake they make over and over without realising it. Here are three Paramarsh students who used the AI Grammar Checker daily to break their habits.

PS

Priya Sharma

IELTS Candidate · Band 7.5 achieved

The candidate who wrote every essay in present tense — even when describing the past.

When Priya first joined our IELTS Writing Task 2 batch, her essays read fluently at first glance. But every examiner flagged the same issue: she described past events in present tense. "In 2015, the government announces a new policy" instead of "announced." Her ideas were strong, her vocabulary was broad, and her arguments were well-structured — but this one habit kept her stuck at Band 6.

Priya started pasting every draft into the AI Grammar Checker before submitting it for review. The AI flagged every incorrect tense, showed her the correct past form, and — crucially — explained why: "Actions completed at a specific past time require past simple." After three weeks of daily checks, the flag count per essay dropped from fourteen to two.

"The AI didn't just tell me I was wrong. It showed me the pattern. I could see my own mistakes stacking up in the report, and after a while I started catching them before I even clicked the button."

Priya's final IELTS score: Writing 7.5 — a full band above her previous attempt. The examiner feedback specifically noted "confident control of past and present narrative tenses."

Rahul Kumar

Job Seeker · Placed at an MNC

The candidate who lost three interviews because of missing articles.

Rahul had technical skills that matched every job he applied for. He also had a cover letter that opened with: "I am writing to apply for position of Software Engineer at your company." The missing the before "position" — and a dozen similar absences — made his otherwise-strong application sound like it was written by someone whose English wasn't polished.

He didn't know what to fix. The sentences felt right to him. This is the article problem: in Hindi, you'd say "position ke liye apply kar raha hoon" — no article anywhere. English quietly demands the position, the role, the opportunity.

Rahul began running every cover letter, every LinkedIn message, every reply to a recruiter through the AI Grammar Checker. Within two weeks, he'd built a personal "watch-list" of ten article patterns the AI kept catching. He started reading his writing aloud with the article question in mind: "Does this noun need the?"

"The tool was like having a strict English teacher sitting next to me — but one who never got tired of explaining the same rule for the tenth time."

Rahul's next four applications all cleared the initial screening. He received three interview calls in a single week and accepted an offer from an MNC in Gurgaon.

Anjali Verma

Marketing Manager · Promoted to Senior

The professional whose emails were "very nice" but never convincing.

Anjali had been a marketing manager for six years. Her emails went out to clients, executives, and her own team — and while they were grammatically correct, they were also flat. Sentences like: "I think maybe we should try a different way" and "That idea is totally stupid" landed awkwardly. She was technically right about both, but the tone was either too apologetic or too blunt.

Her manager gave her feedback directly: "Your English is fine. Your professional voice needs work." Anjali started using the AI Grammar Checker not just for grammar, but for the vocabulary upgrades and improvement tips sections of the report. She'd paste an email draft and study the suggested alternatives.

"I think maybe we should" became "I recommend we". "That idea is stupid" became "That approach carries risk because…". "Very important" became "critical". "Really good" became "excellent".

"The AI didn't teach me new grammar. It taught me new confidence. I stopped apologising for my opinions and started defending them."

Within six months, Anjali was leading the largest client account at her agency. She was promoted to Senior Marketing Manager and now runs internal training on "writing for influence" for new hires — using the AI Grammar Checker as the primary tool.

Frequently Asked Questions

Everything you wanted to ask about the AI Grammar Checker.

Eighteen questions, each with a thorough answer. If yours isn't here, write to us — we update this page regularly with reader questions.

Yes — completely free, with no signup, no email address, and no hidden character limit. You can check up to 1000 characters per submission, which comfortably covers a typical email, a paragraph of an essay, a cover letter opening, or a social media caption. If you need to check longer documents, break them into paragraphs and check each one separately. We built this tool as a free resource for our spoken English and IELTS students at Paramarsh Education, and we intend to keep it free indefinitely.

Our tool sends your text to a large language model hosted by Groq (one of the fastest AI inference providers in the world). The model has been trained on hundreds of billions of words of English text — grammar books, newspapers, novels, academic papers, and millions of conversations. When you submit your sentence, the AI compares it against this enormous body of correct English and generates a corrected version along with explanations for each change. It does not use a fixed rule book — it uses pattern recognition across the full statistical shape of the English language. This is why it can catch subtle issues that basic spell-checkers miss, like tone inconsistencies, awkward phrasing, and register mismatches.

We do not store your text on our servers. The text goes directly from your browser to the Groq API, receives a response, and is discarded. We have no database, no logging, and no analytics on what you submit. This is a deliberate design choice — we believe anyone should be able to check sensitive content (a personal email, a legal clause, a business proposal) without worrying about whether it's being recorded. That said, please use good judgement: never submit passwords, bank account numbers, or other confidential credentials. Grammarly and similar services work the same way; treat online AI tools as you would a stranger reading your draft.

There are four big differences. First, context awareness: Word's checker sees words in isolation; our AI sees entire sentences and paragraphs, which means it can catch issues like wrong prepositions ("married with" vs. "married to"), awkward phrasings, and inconsistent tenses. Second, explanations: Word just underlines something red; our AI tells you why the original was wrong and what rule applies. Third, tone and readability analysis: Word has no concept of professional vs. casual register; our AI does. Fourth, vocabulary upgrades: we suggest stronger, more precise, or more formal alternatives to the words you actually used — Word does not. If you're using this for IELTS or professional writing, Word will help you with typos. This will help you write better.

Yes — this is actually the use case we hear about most. IELTS Writing Task 2 essays are graded on four criteria: Task Response, Coherence & Cohesion, Lexical Resource, and Grammatical Range & Accuracy. Our AI directly helps with the last two. Paste your paragraph into the checker and you'll see exactly which grammatical structures are problematic (helping Grammatical Accuracy), plus vocabulary upgrade suggestions that raise your Lexical Resource score. The readability and formality outputs tell you if the register is appropriate for an academic essay. Do not paste an AI-generated essay — the tool is for checking your own writing. Use it as an examiner-in-your-pocket: write, check, revise, repeat.

Absolutely. PTE's Write Essay and Summarize Written Text tasks both value grammatical accuracy and appropriate vocabulary, just like IELTS. The main difference is that PTE is scored by an algorithm rather than a human examiner, so it's particularly sensitive to surface-level errors like subject-verb agreement, article usage, and verb tense consistency. Our AI catches all of these. For the Writing task in PTE, we recommend checking your essay paragraph by paragraph, paying special attention to the "Corrections" section of the report — PTE algorithms penalise grammatical errors more than IELTS examiners do.

Yes, and this is one of the tool's strongest features for our audience. The AI has been trained on a huge amount of Indian English text — Indian newspapers, business communication, and social media. It recognises the typical Indian-English constructions ("myself Rahul," "do the needful," "prepone," "out of station") and — critically — knows when to leave them alone and when to correct them. "Do the needful" is officially Indian English and appears in Indian Supreme Court judgements — the AI won't flag it in casual contexts. But in an international business email, it will suggest "please take the necessary action." This cultural calibration is something basic spell-checkers cannot do.

Only if you use it wrong. There are two ways to use an AI grammar checker. The lazy way is: paste, hit check, copy the corrected version, move on. You learn nothing, and you'll make the same mistakes forever. The right way is: write your draft, check it, read the "Corrections" section carefully, understand why each change was made, and then — this is the key step — rewrite the sentence yourself without looking at the corrected version. Then check again to see if you got it right. Used this way, the tool becomes a personal tutor that gives you instant, targeted feedback. It accelerates learning dramatically. Used the lazy way, it becomes a crutch. Our recommendation: set a rule for yourself. Never submit or send anything without first trying to fix it yourself. Use the AI as a second opinion, not a first draft.

1000 characters — roughly 150-180 words, or about one long paragraph. This limit exists because the AI needs to return a detailed report (corrections, tone analysis, vocabulary upgrades, tips) for every submission, and longer texts produce reports that are too long to read comfortably. For a full essay, we recommend checking it paragraph by paragraph. This is actually better for learning — you get focused feedback on one section at a time. If you're writing a really long piece, work through it slowly, one paragraph per check.

Both — and punctuation too. The AI catches spelling errors (definately → definitely, recieve → receive, acommodation → accommodation), punctuation mistakes (missing commas, misplaced apostrophes, comma splices), and grammatical issues (subject-verb agreement, tense errors, article misuse, wrong prepositions, run-on sentences). Each correction is labelled with a category — Grammar, Spelling, Punctuation, Word Choice, Style, Articles, or Prepositions — so you can see at a glance what kind of mistake you're making most often. This is incredibly useful for identifying your personal error pattern.

Yes — this is the feature we're most proud of. Every correction comes with a short, plain-English explanation of the rule at work. For example, if you write "I didn't went to the party," the AI will show you "didn't went → didn't go" and explain: "After the auxiliary verb 'did,' always use the base form of the verb. The past tense is already marked by 'did,' so the main verb stays in its base form." This is exactly the kind of explanation a good teacher gives. It turns each check into a micro-lesson, and over time you internalise the rules without ever looking them up.

Absolutely — and if you're writing to clients, senior management, or international colleagues, you should. The tool is particularly good at catching the subtle issues that make Indian business English sound slightly "off" to international readers: overuse of "kindly," awkward apologetic phrasing, missing articles in formal contexts, and register mismatches. It also suggests more confident alternatives to weak phrases. "I think maybe we could possibly consider" becomes "I recommend we consider." "Sorry to disturb you" becomes "Thank you for your time." These small shifts build up to a much more authoritative professional voice.

No AI is perfect, and this tool is no exception. In rare cases, the AI may suggest a change that isn't actually needed, or may miss a very subtle error. Always read the corrections critically — if a suggestion doesn't feel right for your meaning or context, trust your own judgement. Think of the AI as a very well-read friend offering feedback: extremely helpful most of the time, but not infallible. If you notice the AI flagging something that was correct, it's often because the sentence was ambiguous or could be read two ways. Rewriting the original to be less ambiguous usually fixes the issue.

Yes — the tool is fully responsive and works on any modern browser, including Chrome and Safari on iOS and Android. The layout stacks the input and output panels vertically on small screens, so you can paste text in the top panel, tap "Check Grammar," and read the report in the bottom panel. This is genuinely useful during commutes or lunch breaks — many of our students check their practice essays on the train home.

No. Absolutely not. Using AI to generate content and submit it as your own is (a) plagiarism, (b) likely a violation of your institution's academic integrity policy, and (c) counterproductive to your actual learning. What this tool is designed for is checking your own writing — you write the essay, you check it, you learn from the corrections. The improvement happens in the gap between your draft and the corrected version. If you skip writing the draft, you skip the learning. Think of it this way: a calculator is a legitimate tool for checking your maths homework, but it's not legitimate to submit a page of calculator output as your own work. Same principle here.

Indirectly, yes — and the connection is stronger than it sounds. Written grammar and spoken grammar use the same underlying rules, and correcting one strengthens the other. When you use the AI Grammar Checker regularly, you build conscious awareness of rules like subject-verb agreement, article usage, and tense consistency. That conscious awareness gradually becomes unconscious — and it shows up in your speech. The reverse also works: students who take our spoken English classes find they make fewer grammatical errors in writing, because the correct patterns have become automatic in their mouths first. The two skills reinforce each other. For the fastest improvement, combine this tool with daily spoken practice — check your written drafts, then read them aloud.

Because they solve different problems. The AI Grammar Checker gives you written feedback — the "what" and the "why" of every error. Spoken English classes give you real-time human interaction — pronunciation correction, natural intonation, the confidence to speak without freezing, and immediate social context for when a phrase sounds formal or casual. The AI is your reference book; the class is your practice ground. Students who use both progress roughly three times faster than students who use only one. At Paramarsh Education, we've built the AI Grammar Checker as a free tool that complements our spoken English, IELTS, and communication courses. Whether or not you enrol in a course, we hope it helps you write — and speak — with more confidence.

The tool is designed for English — British English and American English both, with slight preference given to standard international English. If you paste text in Hindi, Marathi, Tamil, or any other language, the AI may attempt a translation or refuse to check it. This is not the tool's purpose. Our students occasionally use it to check their Roman-script Hindi ("Hinglish") messages before sending them to English-speaking colleagues, and the AI generally handles that well, but the primary and intended use is Standard English. For regional language support, we recommend dedicated translation tools.

We have no plans to introduce a paid version of the AI Grammar Checker. It exists as a free community resource for our students and the wider English-learning community in India. What may happen in the future: we might expand the character limit, add more tone dimensions, or offer specialised versions tuned for specific exams (IELTS Academic vs. General Training, for example). If we add any of these features, they'll be free additions. Our business model is built around our spoken English courses, not around paywalling language tools. Free stays free.

Five habits will make the biggest difference. One: always write your draft before checking — don't use the tool as a first-pass writer. Two: read the "Corrections" section carefully and try to understand each rule. Three: rewrite the sentence yourself after reading the correction, then check again to confirm. Four: keep a personal "error diary" — note which categories come up repeatedly (if you always have article errors, that's your training focus for the month). Five: check both casual and formal versions of the same paragraph to build tone awareness. Do this for three weeks and the improvement will be visible. If you want structured guidance, consider joining one of our spoken English or IELTS courses — the checker works best as a companion to live instruction.
