Grammar Checker
Fix Grammar Mistakes Instantly
Check grammar, spelling and punctuation: paste any text and Shakespell gives it back corrected, English or Russian detected automatically, with each fix shown next to your original.
Example
was: Their now: They’re going to the meeting on was: thursday now: Thursday, and we was: was now: were discussing the plan.
How do I check grammar in English text online?
Paste your draft into the checker above and run it — grammar, syntax, punctuation, spelling and common word-choice mistakes are corrected together in one pass, and the fixed text comes back in a panel beside your original so you can compare them side by side. There is no language picker; the checker detects English (or Russian, or another major language) on its own. It corrects form and clarity, not your meaning — nothing to sign up for, and no card needed to start.
The web checker is free, up to 5,000 characters per run, and the counter shows what's left. For DOCX or PDF files and your check history, @vustGrammarBot is the same checker inside Telegram.
- Subject-verb agreement and verb tense
- Articles — "a", "an", "the"
- Punctuation, including missing or misplaced commas
- Spelling and common word-choice mix-ups
See the difference
Three real texts, before and after the check — with a short note under each naming what changed.
When the text has to land
The offer goes out tomorrow. One wrong word could cost the deal.
Send Shakespell the letter, commercial offer, formal complaint or report that a deal or a decision depends on and ask for an audit. You get the corrections that matter, each with a short reason, and the places where the wording drifted from what you meant, such as a softened deadline or a sum that now reads differently. You accept or reject each change yourself, so the final text stays yours. For a set of documents, it marks where a key term reads differently from one file to the next.
Check the document that matters before it goes out.

What to expect from this tool.
What it checks
One pass covers grammar, syntax, punctuation, spelling, and common word-choice mistakes. Your original and the corrected version sit side by side — not a separate report you have to map back manually.
Privacy
Your text is sent only to run the check. Do not paste passwords, API keys, or other secrets into any online grammar tool.
Free on the web
The web grammar checker is free to try, no signup. Need more volume or saved runs? Use GrammarBot in Telegram.
Frequently asked questions
What is this grammar checker for?
It is a free, no-signup grammar checker for English and other languages — emails, essays, cover letters, messages, and posts. Paste text, run a check, and the corrected version appears next to your original, so you can compare the two and copy what you need. No account or card needed.
What types of mistakes does it catch?
Grammar, syntax, punctuation, spelling, and common word-choice issues in one pass. Your original text stays on screen next to the result, so you can compare them sentence by sentence.
Does it change my meaning?
No. It corrects form and clarity mistakes. Your facts, names, and intent stay the same unless a word-choice fix is required for correct English.
How is the web tool different from GrammarBot in Telegram?
The web checker is built for quick paste-and-fix runs (up to 5,000 characters): your original and the corrected text side by side, with a before → after change list under the result. GrammarBot in Telegram adds DOCX and PDF files and a history of your checks.
Is this grammar checker free, and is there a limit?
Yes — the web checker is free to try in your browser, no signup. When you need more volume, open @vustGrammarBot in Telegram.
Which languages are supported?
It detects the language from your text and checks English, Russian, and other major languages; Russian text with English fragments goes through in the same run. Non-native English writers get the same one-pass correction as native ones.
Is it a Russian grammar checker too?
Yes. Paste Russian text and it comes back with grammar, spelling and punctuation fixed, including commas, with your original beside it.
Can it audit an important letter or offer, not just fix commas?
Yes. On a vust plan, send @vustGrammarBot in Telegram an important letter, offer or report and ask for an audit. You get the material corrections with a short reason for each and the places where your wording says something other than what you meant, and you accept or reject each change yourself. In a set of documents, it marks where a key term reads differently from file to file. Your documents are used only for this audit and are not kept after it.
Why is it called Shakespell?
Shakespeare plus spell: it fixes spelling, grammar and punctuation so your text reads like it was proofread.
