What AI Detect is
AI Detect is a detector rather than a writing tool. You paste text and it returns a probability that the text was generated by a large language model, together with readability scores, without requiring an account.
What you can do with it
- Check a short passage before submitting
- See an AI probability score
- Review readability alongside detection
- Compare drafts for tone consistency
- Get a signal before human review
Who it is for
- Educators and editors doing first-pass checks
- Content teams screening submissions
- Writers curious how their draft reads
What to watch out for
- Detectors are unreliable in both directions: fluent human writing, formulaic professional text and non-native English get flagged as AI, while lightly edited AI text often passes
- Accuracy figures quoted by vendors are their own testing, not real-world reliability
- Never use a score alone as evidence of misconduct; pair it with process evidence, drafts and a conversation
- Text you paste is sent to a third party, so do not submit confidential or unpublished material

FAQ
Is a high score proof of AI use?

Who is most often misjudged?
Non-native English writers and people using formal or templated language.
What should I avoid pasting?
Anything confidential or unpublished, since text is processed externally.
