Check if an essay reads as AI-written
Paste an essay and get an analysis of how AI-like it reads, with the specific patterns explained.
For the best results: Paste the complete essay rather than a fragment, verdicts on short excerpts are much less reliable. The result is a stylistic estimate, not proof.
What is AI Essay Detector?
AI Essay Detector is a free AI writing tool that analyzes an essay for the writing patterns typical of AI-generated text and explains exactly what it finds. Your brief is routed to a model suited to writing work and comes back as polished, original writing drafts tailored to your tone and purpose in seconds. No account stands between you and the draft, and what you write is cleared when you close the tab, not banked.
- ✦Write immediately, with no account standing between you and the draft
- ✦Every request is routed to a model suited to writing work
- ✦Drafts and prompts are cleared when you close the tab
Models: It routes across leading models including Gemini, Llama and Mistral families, picking the best available one per request. The exact model used is shown after every response.
See it in action
A tutor gets a submitted essay whose tone feels a little too even and wants the specific patterns flagged before raising anything with the student.
What you type
[pasted 900-word essay on climate policy]
What you get
Likelihood of AI involvement: high What drove it: - Uniform sentence length across all 14 sentences (little of the natural variation human drafts show) - Repeated scaffolding phrases: "Moreover", "It is important to note", "In conclusion" - Every paragraph opens with the topic and closes with a tidy restatement - No hedging, asides, or specific personal examples anywhere in the text Caveat: this is a probability signal, not proof. A careful writer can trip these same flags.
Tip: Treat a high score as a prompt to look closer, never as a verdict. Detectors flag patterns, so paste the whole piece rather than a paragraph, since consistency across the full length is where the real signal lives.

How it works
- 1Describe what you need written, with tone and audience.
- 2A writing-tuned model drafts it to your brief.
- 3Copy the draft, or ask for a tighter, longer, or different-tone version.
Tips for the best results
- Paste the complete essay, since the patterns show across paragraphs rather than in a single line.
- Read the explained patterns to learn which habits, even pacing and hedged, formulaic phrasing, read as machine-made.
- Remember a human-written essay can still flag, so treat the analysis as feedback, not proof.
- Rework the flat, uniform sentences with specific detail and a natural change of pace.
- Re-run after revising to confirm the writing now reads as your own.
FAQ
Frequently asked questions
Can a teacher use this to prove a student used AI?
No, and that's a design position, not a disclaimer. The analysis is a stylistic estimate, not a validated classifier, and stylistic evidence alone can't establish authorship in either direction. Formulaic writers and students working in a second language get flagged by pattern-based analysis disproportionately. Use the findings to open a conversation and compare against the student's known writing, never as the basis for an accusation.
I wrote every word myself, so why does it read as AI-like?
Because taught academic style overlaps heavily with machine style. The five-paragraph structure, stock transitions like 'furthermore', evenly weighted sentences and hedged conclusions are exactly what schools reward and exactly what AI produces. The analysis shows you which of those habits your essay leans on, which is useful to know even when the explanation is simply that you write the way essays are taught.
Will Grammarly or heavy editing make my essay look generated?
Light corrections, spelling, punctuation, the odd word swap, barely move stylistic patterns. Full-sentence rewriting tools are different: accept enough of their suggestions and your prose genuinely drifts toward machine phrasing, because machine phrasing is what produced it. The analysis can't tell you which tool caused a pattern, only that the pattern is present, so keep your drafts if you lean on editing software.
How should I revise an essay that comes back reading AI-like?
Work on the patterns the analysis names rather than swapping synonyms. Vary sentence length deliberately, replace stock transitions with ones that carry your actual logic, commit to positions instead of hedging everything, and let one genuinely specific example interrupt the abstractions. Then run the revised essay through again to see which of the original flags have cleared.
A detector at uni flagged my work. Will this clear me?
No tool can certify that you wrote something, this one included, and anything claiming otherwise is overselling. What it offers an accused student is comprehension: a plain-English account of which stylistic features look machine-typical, so you can respond specifically instead of just denying. Your stronger evidence lives elsewhere, in draft versions, document edit history and notes, so gather that first.
Is the essay detector free with no sign-up?
Yes. Paste an essay and get an analysis of how AI-like it reads at no cost, with no account or payment. Run as many checks as you need while revising. Nothing is held back behind a paid plan and there is no watermark on anything.
Is my essay stored when I check it?
No. Your essay is analyzed for the check and not kept afterwards or added to any database, so pasting your own work here will not cause it to resurface elsewhere. Once you close the tab the text you checked is gone. Copy out any notes you want to keep.
Does it work on essays in other languages?
It is tuned for English, where the machine-writing patterns it explains are clearest. You can paste other widely used languages, but read the analysis as a looser guide there, since the signals are less reliable outside English. Treat any result as feedback, never as proof.
What are the usage limits?
Writing tools are unmetered during the current free launch phase, draft, redraft, and polish without counting requests. Only a short per-minute anti-abuse limit applies, which normal writing never touches. Paid plans with higher limits and priority model access are coming soon.
