No detector-panel result exists for ZeroGPT. Anything on this page about detectors below is the vendor's own claim, not a measurement. Ask us to test it, or run the procedure yourself.

"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
“98.4% Detection accuracy; <1% False positive rate”
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 ZeroGPT. What is above is what the vendor says about itself.
Vendors can ask for a review. Buyers can ask for one too - tell us which tool you need checked.
