text detector
Paste any text and get an honest estimate of how likely it was written with AI: a percentage, the signals behind it and how confident the check is. We show our working because no AI detector is reliable enough to be the final word.
Result
// How it works
Two checks, one honest number
- Writing statistics. How much sentence length varies, how varied the vocabulary is, and how often stock chatbot phrases appear. This part needs no AI and always runs.
- An AI reading. A language model reads the text and quotes the phrases that look machine-written or human-written.
- One estimate. We combine both (60% model, 40% statistics) and show a confidence level. Confidence is never "high": short texts and disagreements between the two checks are marked low.
// Limits
What an AI detector cannot tell you
- It is not proof. Every AI detector, including paid ones, flags some human writing as AI and misses some AI writing.
- Some writers get flagged more. Non-native speakers, formal or technical writing, short texts and heavily edited text often look "machine-like".
- Edited AI text is hard to spot. A few human edits can change the result a lot.
- Never the only evidence. Do not use it alone to accuse a student, reject a candidate or refuse to pay a writer. Talk to the writer, look at drafts and version history.

AI detector questions
Is this AI detector free?
Yes. No sign-up and no payment. Each visitor gets a few AI-assisted checks per day; after that the tool still answers from the writing statistics alone.
How accurate is it?
Treat the result as an estimate, not a verdict. No AI detector is reliable enough to prove who wrote a text. Our result shows a confidence level and the signals behind it so you can judge for yourself.
Why does it never say 100%?
Because nobody can know that from the text alone. Tools that claim certainty mislabel real people. We keep the estimate between roughly 5% and 95% and say when the evidence is weak.
Can I use it to check student essays?
You can use it as one signal, but never as the only evidence. Students who are non-native speakers or write formally are flagged more often. Talk to the student and look at drafts first.
How long should the text be?
At least 150 words for a useful estimate, up to 5,000 characters (about 800 words). Under 40 words the tool will not give a verdict.
Is my text stored?
No. The text is sent to our AI once and is not saved or used for training. Only the result is cached anonymously for up to 24 hours.
