Scores come from an established third-party detection service, not a homegrown scoring trick.

You get the passages that carry the signal, not one number with no explanation.

Revise flagged passages, rescan with the same detector, and compare what changed.
A trail, not a claim
Every saved version records the result and changes without pretending a score proves authorship.
A clear read, with a useful next step.

Questions
Is the AI detector free?+
Yes. You can run up to 3 real AI checks a day on 150-500 words each without an account. Create a free account for longer drafts, the complete report, focused rewrites, rescans, and version comparison.
Why is there a 150-word minimum?+
AI detectors, ours included, are unreliable on short text, close to a coin flip below roughly 150 words. We would rather ask for more text than give you a result we do not trust.
Can an AI detector be certain?+
No. A detection result is a signal, not proof. Review it in context, especially for short or heavily edited text.
What happens when I paste more than 500 words?+
We will ask you to create a free account before any analysis runs. Your full draft follows you into the detector and is checked after signup.
