A plain, honest checker that is not AI. It uses a large dictionary and written pattern rules to flag spelling, confusion pairs and common slips, and it tells you what it cannot do.

This Grammar Checker is not AI, and it does not pretend to be. It works from a dictionary of about 379,000 words held in the page plus a written set of pattern rules. It flags common slips, shows the reason for each one, and offers a one-click fix.
Paste your text and run the check. The dictionary side covers spelling with ranked suggestions, and it flags US and UK spellings with the matching form for the variety you picked. The rule side covers repeated words, could of, should of and would of, a and an agreement, and double spaces or a space before punctuation.
It also checks common confusion pairs in context, among them their and there, your and you are, its and it is, to and too, then and than, and loose and lose. It catches alot and eachother, missing capitals at sentence starts and for the pronoun I, missing ending punctuation, and basic subject and verb patterns such as he do not or they was. A comma splice warning appears as a heuristic warning, not a certain error, because some splices are a style choice.
Each finding shows why it was flagged and offers a fix you can apply with one click. An apply all button handles the full set in one pass. If a flagged word is right, you can ignore it into a personal dictionary kept in your own browser, so names and terms you use often stop nagging you.
Writers run a last pass here before sending work they cannot afford to get wrong: a job application, a client email, a school essay or a post that will carry their name. The checks suit that final sweep because the slips it hunts are the ones tired eyes skip.
Non-native speakers use it for the pairs that spell check alone cannot sort. Loose and lose both sit in the dictionary, so only a rule that looks at the words around them can raise a hand. Students use it to learn the patterns behind their own repeat errors, since each finding states its reason instead of just rewording the line.
Teams without a paid suite use it as a shared first check. AI suites often cap guest use at 500 to 1000 words per check and a few checks per day. This page has no length limit and no daily cap, so a long report can be checked in one go.
Fixes are always your call. The tool suggests, you decide, and nothing in your text changes until you click. Apply all is fast for a clean draft, while one by one review suits text with names, quotes or dialect that a rule may read wrong.
The personal dictionary lives in your browser only. Add your name, your town, product names and trade terms once, and later checks on this device will pass them. Clear your browser storage and that list goes with it, which is worth knowing before you rely on it for a long project.
It cannot understand meaning. It cannot catch every error, or even most errors, and it makes no claim about accuracy and shows no accuracy percentage. It cannot judge style, tone or whether a sentence says what you meant. A comma splice flag is a prompt to look, not proof of a fault.
A typo that lands on a real word passes a dictionary without a sound. If you type form where you meant from, or loose where you meant lose in a spot the rules do not cover, the check may stay silent. Read your work aloud once after any checker, human or software. That slow read still catches the sense errors no pattern rule can reach.
No. It uses a dictionary of about 379,000 words and a written set of pattern rules, all held in the page. There is no language model, no training data and no server call. That is why its limits are stated so plainly.
Spelling with suggestions, US and UK mix-ups, repeated words, could of type slips, a and an errors, confusion pairs like their and there, missing capitals, double spaces and basic subject and verb faults.
Sometimes, when a rule covers the pair and the context matches, as with their is at a sentence start. Often it cannot. A dictionary passes any real word, so read the final draft yourself once.
No. Check text of any length as often as you like. Paid suites often limit guests to short checks a few times a day. This page runs fully in your browser, so no such meter is needed.
A list of words you choose to ignore, such as names and trade terms, stored in your own browser. Later checks on the same browser pass those words. It is not shared, uploaded or synced.
No. It flags pattern based slips and explains each one. Word choice, tone, flow and whether the argument holds together stay with you and your readers. Treat it as a first sweep, not an editor.
