Paste English and every issue is underlined where it happens, labelled spelling, grammar, punctuation or style, with the reason attached. English is written in the Latin alphabet, and subject–verb agreement, articles, tenses, commas and apostrophes are what a checker has to get right in it. This one shows the rule each time, not just the change, so you can accept the fix, ignore it, or learn from it.
Three steps. The third is the one most checkers leave out.
Type, paste or drop in a document. English is already selected as the language on this page; the menu above the editor also offers the variants described below. If the text turns out to be something else, the detector says so and you can change it.
Every flag is underlined in the text and listed beside it. Spelling and grammar flags are errors; punctuation and style flags are judgements, and the label tells you which is which before you decide.
Click a flag to see the fix and the rule behind it, then accept it or ignore it. English has rules that speech does not reveal, and the reason is there so the same error is not made twice.
The parts of English grammar and spelling where a checker has to know the language, not just the words.
Five errors English readers notice at once, and what the checker does with each.
It's is always it is or it has; its is the possessive, like his. Your is possessive, you're is you are. The pairs sound identical and the checker reads the sentence, not the word, to decide which is meant.
The results were clear, the board approved the plan. Two complete sentences cannot be joined by a comma alone: use a period, a semicolon, or a conjunction (clear, so the board …). This is the error most often marked in student and business writing alike.
The range of options are limited — the subject is range, so it is is limited. When a plural noun sits between the subject and the verb, the ear follows the nearer noun and the grammar follows the subject.
English needs an article before most singular countable nouns (I bought a car, not I bought car) and none before general plurals and uncountables (information, advice, research). Writers whose first language has no articles, and native writers in a hurry, both drop or add them; the checker flags each with the reason.
Colour in one paragraph and color in the next, or organise beside analyze, reads as carelessness. Choose US or UK in the language menu and the checker holds the document to that system.
Formal English avoids contractions (do not, rather than don't), phrasal verbs where a single verb exists (examine rather than look into), and the second-person you in reports; it prefers full sentences to fragments and keeps exclamation marks for direct speech. Informal English does the opposite and is right in messages, marketing copy and much of the web. The checker never forces one on you; it flags a contraction in a formal document or a Latinate construction in a chat message as style, with the register named.
The checker flags a mixed register as style rather than as an error, so the decision stays yours. If a whole text needs to move from one register to the other, the tone changer rewrites it in one pass.
Students writing essays, dissertations and applications in the variety their university expects.
People writing English at work as a second language, where an article or a tense slip is the difference between fluent and foreign.
Native writers polishing reports, emails and web copy where a comma splice or a stray apostrophe costs credibility.
Yes. Check English without an account, within the per-check and daily word allowances shown beside the editor. Signing in raises them, and Pro removes the guest limits and the ads. The pricing page lists what each plan includes.
American English is preselected on this page; change the language menu above the editor if the text is a different variant.
Yes, and in English the two overlap. American and British spelling differ in a few regular patterns — color / colour, organize / organise, center / centre, traveling / travelling, defense / defence — and a document must follow one system throughout. English (US) is preselected on this page; English (UK), Canada, Australia and India are in the language menu, and each applies its own spelling, dates and quotation conventions. Canadian usage takes British -our and -re with American -ize; Australian and Indian English follow British spelling. Each of these is underlined where it happens, labelled spelling or grammar, with the standard form and the rule beside it.
Not unless you ask it to. A check corrects what is wrong and leaves your sentences as you wrote them; every change is a separate flag you accept or ignore. The Improve and Rewrite passes, which do change wording, are separate buttons, and the paraphraser is a separate tool.
Yes. Paste the text or drop in a .docx, .pdf or .txt file; the document is checked paragraph by paragraph and the corrected version can be copied or exported. Long documents are checked within the per-check allowance and continue as you scroll.
That is where the reason attached to each flag earns its keep. English has almost no inflection left, so agreement shows in only a few places and errors there stand out: a singular subject takes -s on the present-tense verb (the report shows), a plural does not (the reports show), and a subject separated from its verb by a long phrase — the list of items are — is where native writers slip most. A learner sees which rule was broken, not just the corrected word, and can accept the fix or read why it was raised before deciding.
Translate the corrected English, change its tone, or shorten it. One plan covers every tool.
Each page opens the checker with that language already selected and explains what it looks for in it. The picker above the editor covers more than seventy languages in all.
