Stop playing
AI detective.

Signet gives your students a way to show their work — and gives you evidence instead of a probability score.

Your student writes in Google Docs the way they always do. Signet records the shape of the process — sessions, timing, typed versus pasted, sources tagged — never the words. They submit a verified certificate with their paper. You check it in seconds, from any browser, no account.

A full Signet Certificate render

What it does.

Students cite their AI use — in the record itself.

The most-requested feature from instructors, built in: when a student pastes anything from outside their document, Signet asks them to tag and declare the source — "ChatGPT — brainstorming," "quote from assigned reading." The declarations appear in the certificate’s Process & Sources appendix next to Signet’s own measurements, so disclosure is documented at the moment it happens, not reconstructed under pressure later.

It records the process, never the words.

Sessions, timing, typed versus pasted, revision patterns. The syncing code has no access to document text. The one exception is opt-in and plainly labeled: revision views a student chooses to include (see Rewind below) — rendered images of moments from their document’s history, shown to verifiers.

Two report types, honestly tiered.

Certify live-witnesses the writing as it happens — the strongest record. Rewind builds a report after the fact from the document’s Google Docs revision history — for papers written before Signet was installed. Rewind reports are clearly labeled Reconstructed tier, lower assurance than live witnessing, and say so on their face. The tier is never hidden from you.

Verification takes seconds and trusts no one.

Scan the certificate’s QR code, or drop the certificate — or the submitted paper itself — at getsignet.app/verify. The paper is matched to its certificate by a browser-side fingerprint, so you can confirm the exact file you’re holding is the certified one. No account, no upload, nothing leaves your browser.

One line in your syllabus.
That’s the whole lift.

Students install a free extension and write the way they always do. They submit one extra PDF with the paper. You verify it in seconds.

Syllabus snippet — copy and paste

Written assignments in this course are submitted with a Signet Certificate. Signet is a free Chrome extension for Google Docs that documents your writing process — sessions, timing, what was typed versus pasted — and produces a verifiable record. It is not an AI detector and never reads the content of your writing. Install it before you begin drafting: getsignet.app/academic/students. Submit the certificate PDF with your paper.

Convergence towards process records

The major integrity tools now agree that detection alone failed and the writing process is the evidence that matters. Where they differ from Signet is structural — and the structure is the whole question, because a process record is only as trustworthy as the party holding it.

As of July 2026, from each vendor's published documentation.

The pattern: every other process tool asks you to trust a party with a stake in the answer, holding a copy of the writing. Signet is built so there's nothing to trust — the witness can't see the words, sells no verdict, and the record verifies without us.

Open beta.

Signet Academic is in open beta and under active development — interfaces and record formats will keep improving, and you may find rough edges. One thing is fixed: certificates issued during the beta remain permanently verifiable at their verification URLs. Verification never depends on version-specific software.

Try it on one assignment this fall.
