Not prompted, not pasted — written. Proofwriter already verifies documents; this brings the same idea to everyday email, free, for every account.
Install the extension
Click "Add to Chrome" above.
Click Connect
Click the extension’s icon in your toolbar, then "Connect." A new tab opens on proofwriter.app — sign in there if you’re not already.
Copy the one-time code
That page shows a short code, generated just for you. Copy it — the tab closes the extension’s popup when it opens, and that’s expected.
Paste it back in
Click the extension icon again and paste the code into the popup. That’s the whole connection — you’re done.
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.
Free with any Proofwriter account — the extension works with your existing sign-up.
