Every piece of writing that ENTRUST AI APEX releases carries a receipt signed with one key. This page checks a receipt against that key. The check runs inside your own browser: the receipt is fetched from APEX by its number, and nothing you paste here is uploaded, stored or sent to us.
This is APEX's fingerprint. Every genuine APEX result shows the same line, written as Signed by. A result showing any other fingerprint did not come from APEX.
Type the receipt number from the certificate — the line that begins Run ID: — and press Look up. APEX sends back the signed receipt and this page checks it here.
Or paste the certificate lines from your chat, from Certification: to the link, and press Check.
Certification — the judgement APEX reached. ENTRUST_CEILING means the work passed every gate APEX applies and was released. APEX releases nothing below that line.
Run ID — the single run that produced this text. It names that run and no other.
Signed by — the fingerprint above. It is what ties the result to APEX rather than to anyone claiming to be APEX.
ENTRUST AI APEX writes or checks text that matters, and releases it only when it survives an adversarial examination: independent drafts, blind comparison, a defect judge, a challenger trying to beat it, and a final arbitration. Whatever fails is withheld, with the reasons. Whatever passes carries the receipt you just checked.
It runs on entrustai.co and inside ChatGPT, and a new account gets 3 replies free.
