How to Use
Paste or type your text into the editor. Checking starts as soon as you stop typing, and your word count, reading ease and grade level appear on the right.
Read the suggestions. Each card names the problem, explains it in one line and offers a replacement. Click the replacement to accept it, or Ignore to keep your wording. Unknown names can be added to your own dictionary.
Use "Fix all safe issues" for the clear-cut ones, switch to Statistics for readability and reading time, then copy the text or download it as a .txt file.
About This Tool
Grammar & Writing Checker proofreads your text as you type and never sends it anywhere. It checks spelling against a built-in English dictionary of more than 170,000 words, applies around fifty grammar, punctuation and style rules, and explains every suggestion in plain English so you can decide whether to accept it. It flags the classics — its and it's, their, there and they're, affect and effect, should of, more then, double words, double spaces and a space before a full stop — along with wordy padding, tired cliches, filler words, the passive voice, sentences that have run too long and paragraphs that start the same way twice. Choose American or British English and it will accept either spelling, or convert the whole document from one to the other in a click. Writing goals for blog posts, emails, business reports and academic work change how strict the length and passive-voice checks are. Alongside the suggestions you get Flesch Reading Ease, Flesch-Kincaid grade, the Gunning Fog index, word, character, sentence and paragraph counts, and reading and speaking times. Fix everything safe in one click, copy the result or download it as a text file. Your draft is saved in your own browser, so nothing is lost if you close the tab.
Frequently Asked Questions
No. The whole checker, including the dictionary, runs inside your browser, so your writing never reaches our server. A copy of your draft is saved in your own browser so you do not lose it if the tab closes, and the Clear button removes it. That makes the tool safe for contracts, medical notes, coursework and anything else you would not paste into an online service.
This is a proofreader, not a rewriter. It looks for mistakes it can point to and explain, and it leaves your voice alone. Because the rules are fixed rather than generated, it will never quietly change your meaning, invent a sentence, or need an account or an internet connection after the page has loaded.
The ones people actually make: its and it’s, their, there and they’re, your and you’re, affect and effect, then and than, to and too, lose and loose, "should of" for "should have", "we was" for "we were", "a apple" for "an apple", repeated words such as "the the", contractions typed without an apostrophe, double spaces, a space before a comma or full stop, a missing space after one, missing capitals, unbalanced brackets and quotes, and about fifty rules in all. It also flags wordy phrases, cliches, filler words and the passive voice as style suggestions you can switch off.
Choose United States or United Kingdom at the top. Either way the checker accepts both spellings of a word it knows, so you will not be nagged for writing "colour"; it only flags a spelling that belongs to the other variant. "Convert spelling" rewrites the whole document into the variant you picked, covering around 295 word pairs such as colour/color, organise/organize, centre/center, travelling/traveling and favourite/favorite.
Reading ease is the Flesch Reading Ease score, from 0 to 100. Above 70 is easy, 60 to 70 is plain English, and below 50 is hard going. Grade level is the Flesch-Kincaid grade: the US school year a reader would need to follow the text on first reading. Most news writing sits around grade 8 to 10. The Statistics tab also shows the Gunning Fog index, your longest sentence, and how long the piece takes to read aloud.
Only the fixes that have one obviously correct answer: double spaces, a space before punctuation, a missing space after a comma, repeated words, "should of", "more then", a lowercase "i", "alot", and a few others. Anything that depends on your meaning - its versus it’s, their versus there, style and wordiness - is left for you to decide, one card at a time.
