How detectors score text, how accurate they really are, who gets falsely flagged, and what to do about it.
Start learning →Detection is a guess. Provenance is evidence.
An AI detector looks at finished text and estimates how likely it is that a machine wrote it. A writing record shows how the text actually came to exist. Both have a place, but only one can back up a claim.
AI detection
- Works on any text after the fact
- Gives a probability, not an answer
- Wrongly flags some human writers, especially formal, simple, or non-native English writing
- Can be fooled by paraphrasing and light editing
Prove Human
- Records the writing process as it happens
- Shows typing, revisions, pastes, and time spent
- Gives the writer a certificate anyone can verify
- Protects honest writers instead of putting them on the defensive
