AI Detector: estimate whether text was written by AI
Paste a passage and get a likelihood score with a short explanation.
Likelihood score
A 0 to 100 estimate of how likely the text is to be AI-written.
Plain explanation
A short note on the writing patterns behind the score.
Honest limits
Detectors are estimates, not proof. We show that on every result.
Frequently asked questions
How does it work?
An AI model reads the text and judges patterns such as uniform tone, repetitive structure, and generic phrasing.
How accurate is it?
Not perfectly. AI detection is unreliable, especially for short, edited, or non-native writing. Treat the score as one weak signal, never as proof.
How much text can I check?
Between 50 and 10,000 characters per check.
What does it cost?
Each check costs 2 credits. New accounts start with 500 credits.
