Not prompted, not pasted — written. Proofwriter already verifies documents; this brings the same idea to everyday email, free, for every account.
Write
Compose like normal
The extension quietly watches your compose window — no setup, no extra window, no change to how you write email.
Flag
Pasted text gets flagged
The same paste-detection Proofwriter uses in its editor runs on Gmail’s compose box, so a pasted paragraph is recorded, not hidden.
Verify
A verified link lands in your signature
Once you send, the link resolves to a public page showing word count, time spent, and whether anything was pasted — never the email itself.
It's for the writer who wants proof, not a promise, behind every byline, submission, and now every email — free, unlimited, no catch. The extension never stores what you write; only the process, and only for the specific message someone clicks through to.
Sign up free — the extension follows once your account is ready.
