About AI Essay Checker

One job: show you the score before someone else does

AI Essay Checker checks a piece of writing for patterns typical of machine-generated text and shows you a score — with the flagged sentences or passages highlighted, so you know which lines raised a flag and which didn't. That's the whole product. It's free, it needs no signup, and the essay you paste in is not stored.

Students use it in the week before a deadline, usually late at night, usually nervous. The point isn't to help anyone fake authorship — it's the opposite. Human writing now gets flagged too: writing that's too smooth, too even, too carefully transitioned looks statistically like a machine. Seeing your own score before a reader does is the difference between fixing three sentences and explaining yourself to an admissions office.

How the check works — and where your essay goes

We don't run our own language model. Your text is sent to a third-party commercial AI detection service, which returns the scores. We do not save the text and we do not use your essay to train models; we ask the service for no-retention handling wherever it offers that option, and it processes the text under its own terms. The result comes back to your browser and is rendered on screen. We don't write it to a database, because there is no database of essays.

Two practical consequences you'll notice: essays must be between 500 and 12,000 characters (about 2,000 words; shorter text returns low-confidence scores — too little signal to judge), and each visitor gets a daily number of free checks. The limit exists because every check costs us real money, not to nudge you toward a paywall — checking is free and stays free.

Who runs this

AI Essay Checker is an independent project built and maintained by one developer. No agency, no investors, no content farm — which is also why the limits are modest and the tooling is deliberately boring.

If something is broken, wrong, or you want to know how a page was researched, write to support@aiessaychecker.io — it goes to a person, and it gets answered.

What we don't do

• We don't write essays. Nothing on this site generates text for you.
• We don't guarantee results. No detector, ours included, can prove authorship, and admissions outcomes aren't something any tool can promise.
• We don't sell data. There's no account and no essay archive to sell.
• We don't claim to be your school. Your institution's rules — and its own detector — are what actually apply.

How our guides are written

Pages like the 7-point essay grader rubric and the 12-point pre-submission check are assembled from primary sources: the published Common App prompts and word limits, provider documentation on how detection scores are calculated, and the published rubrics schools and counsellors actually use. Every page is written and edited by a human before it goes live, and claims about word counts or formats link to the source. If you find an error, the contact address above is the fastest way to get it fixed.
