FREE AI TEXT DETECTOR
AI text detection, made simple.
Paste your text. Get an AI percentage and sentence highlights. No sign-up, no extra steps.
AI detection is an estimate, not proof of authorship. Use the result as one part of your review, never as the only basis for a decision.
LESS GUESSWORK, MORE CONTEXT
An AI writing check in three steps.
- 01
Paste your text
Add an essay, article, or draft directly above. English passages of at least 100 words give the detector more context.
- 02
Check the AI signal
Get an overall AI percentage indicator. It reflects the detector’s signal, not how many words were written by AI.
- 03
Read the highlights
Review your writing sentence by sentence. Yellow marks stronger AI signals; green marks weaker signals.
GOOD TO KNOW
A few straight answers.
Is this AI detector free?
Yes. You can check text for free, with no account or sign-up. Paste up to 5,000 words into the detector on this page. Some unusually long or complex passages may need to be shortened.
What does the AI percentage mean?
It is a summary of the detector’s AI signal. A higher percentage means stronger AI-like patterns, not a calibrated probability or a measurement of how much text AI wrote. Sentence highlights help you see where those patterns appear.
Can an AI writing detector be wrong?
Yes. Human writing can be flagged, and AI writing can be missed. Short passages and edited or mixed writing can be harder to interpret. Compare the result with the writing’s context and the author’s process before drawing conclusions.
Do you save the text I submit?
We do not keep a scan history or log your submitted text. Your passage is held temporarily in a processing queue while the scan runs. Operational logs record counts, timings, and outcomes. Keep the page connected until the result arrives; if you disconnect, you will need to submit again.
