"Not stated" means the vendor does not publish it, or publishes it somewhere we could not read at the source. It is not a judgement, and we do not fill the gap with an estimate.
The accuracy the vendor claims
“99% accurate, with under 1% false positives”
Source: the vendor's own page.
No accuracy figure on this site has been independently audited, and every detector produces false positives on genuine human writing. Treat a detection result as a reason to look closer, never as proof.
No score yet, and here is why
A score on this site means a person used the tool, ran the fixed test texts through 6 detectors and published the numbers with a date. That has not happened for Detecting-AI. What has happened: we read the vendor’s own pages and recorded the price and the limits with a link and a date. Those are above.
Vendors can ask for a review. Buyers can ask for one too - tell us which tool you need checked.
