A simple way to show a human wrote it.

We check your writing independently, then give you a certificate, a page in our public registry, and a trust mark you can put on the work.

The case

Why should you certify?

Editors, clients and readers are increasingly sceptical of whether a person wrote something. Certification gives you something to point at, instead of asking to be taken at your word.

Three ways in

What you can certify

One article, essay or post

A single piece

Paste its URL or upload the file. You pay once and the certificate is permanent.

One newsletter or blog

A publication
