Free AI detector for essays
Paste your essay, discussion post or report and our AI Scanner marks every sentence: red where it reads AI-generated, amber where it's worth a second look, green where it reads human. Free for up to 500 words, no account needed.
How it works
Paste your text
Drop in a paragraph or a full draft — the free scan covers the first 500 words.
Click Scan
Each sentence is scored for AI-style writing, and you get an overall AI likelihood.
Fix the flagged lines
Rewrite the red and amber sentences in your own voice, then scan again.
Why sentence-level results matter
A single percentage tells you there's a problem but not where it is. Highlighting each sentence shows exactly which lines carry the AI patterns, so you can revise a few sentences instead of rewriting the whole paper.
What the colours mean
Red sentences read strongly AI-generated: predictable phrasing, filler transitions and generic claims. Amber sentences show some of those signals and deserve a reread. Green sentences read like a person wrote them.
Before you submit to Turnitin
Universities increasingly run submissions through AI detectors such as Turnitin and GPTZero. Scanning first lets you catch the passages most likely to be flagged while there's still time to revise them.
No detector is perfect
AI detection is an estimate, not proof. Formal academic writing can occasionally score higher than it should, and heavily edited AI text can score lower. Use the result as a guide to what to revise, not a final verdict.
Frequently asked questions
Is the AI detector really free?
Yes. Every scan covers up to 500 words at no cost and without an account. For longer documents, message us on WhatsApp for a full report.
Do you store the text I scan?
No. Your text is sent to the scoring model and the result comes straight back to your browser — we don't save or log it.
Will my paper pass Turnitin if it scores low here?
A low score is a good sign, but different detectors use different models, so no tool can guarantee another tool's result. Stricter detectors like Turnitin and Pangram may still flag text that reads as mixed here.
Can you rewrite the flagged sentences for me?
Yes. Send us the text on WhatsApp and one of our writers will revise it in a natural, human tone while keeping your argument and citations intact.
