Grammar & Style Checker
Catch common grammar, spelling and punctuation slips, with one-click fixes.
How to use: Type or paste your text. Issues are underlined by type and listed below with suggested fixes. Press Fix on one issue or Fix all.
Rule-based checker covering frequent mistakes (a/an, repeated words, common misspellings and mix-ups, capitals, spacing, punctuation) and style hints. It is not a full AI proofreader, so it will not catch everything.
How to use the Grammar & Style Checker
A quick check before you send an email, post or assignment catches the small mistakes that are easy to miss when you have read your own words many times. This checker runs in your browser, so even confidential drafts stay on your device.
As you type, the text is scanned with a set of rules. Grammar rules catch “a” before vowel sounds and “an” before consonants, doubled words such as “the the”, a lowercase “i”, sentences that start without a capital and mix-ups like “should of” instead of “should have”, “more then” instead of “more than” and “your welcome”. A spelling list catches frequent misspellings such as definately, seperate, recieve and occured. Punctuation rules flag spaces before commas, missing spaces after them and repeated exclamation marks.
Style hints, shown in a different colour, point out possible passive voice, filler words like “very” and “really”, and sentences longer than 30 words. These are suggestions, not errors. Each issue explains why it was flagged, and most have a one-click fix; Fix all applies every safe correction at once.
Rules cannot understand meaning, so this tool will miss some errors and occasionally flag correct text. Use it as a helpful second pair of eyes, not a final authority.
Frequently asked questions
Does it check spelling for every word?
No. It checks a list of commonly misspelled words. Your browser’s built-in spell check underlines other unknown words.
Is my text sent to a server?
No. All checks run in your browser.
Why is passive voice flagged?
Passive sentences are not wrong, but active voice is usually clearer and shorter. It is a style tip you can ignore.
