Is this AI output
really sealed?

Paste any AI-generated text, or a Crovia seal ID. We verify, cryptographically and in your browser, whether Crovia actually issued a seal for it — and if so, when, by whom, with what generator.

01 · Input

The seal id is a short identifier returned by every /v1/sign call. If the text came from a Crovia-sealed source, the id is also hidden in the output via zero-width CIM markers — use the other tab to extract it.
If the text contains a Crovia CIM (Conversational Inline Marker, zero-width Unicode characters), we will extract and verify it here. Invisible CIMs survive copy/paste through almost any app.
