Record what you write, where you write it, and publish a record that a person typed it. Proof that you typed it. Click into a text box (an email, a LinkedIn post, a Reddit comment, a comment) and a small chip offers to record it. Click the chip and it records how the text came to exist: every change, and when. When you are done, it publishes the record on this-is-not.ai along with proof of the session and puts one line in the box: "Typed by hand in 12 minutes" and a link. Anyone who follows the link watches the writing happen. Post it, and the proof is linked back to the post, so the two point at each other. What it says is small and true: this text was typed by a person, live, in one sitting, on this date. It is not AI detection. Nothing inspects your words or guesses at their origin. Though every session is logged and could be inspected in the future. HOW IT WORKS 1. Write. The chip sits on the box you are writing in. Click it and the record begins, including the sentence you typed while deciding. 2. Publish proof. A small window opens on this-is-not.ai, a human check runs, and the proof line goes into your text. 3. Post. The extension sees the proof's link in what you posted and links the post to the proof. In Gmail, send; an email has no page to link. Pasting is refused while it records, as it is in the editor on the site. A quote tool lets other people's words in, marked as theirs. A web address on its own can be pasted. In Gmail, your signature and any quoted thread are cut out before the record is made. WHAT LEAVES YOUR MACHINE While it records, every thirty seconds the draft so far is sent to this-is-not.ai, which hashes it, signs the hash with the time, and keeps neither the draft nor the hash. That is how the record can later show the piece was typed over that time, and it is what the site's own editor does. Nothing is stored until you press Publish, and then the record goes to the site in front of a human check. WHAT IT DOES NOT DO It records one box at a time, only after you click its chip. Boxes without a chip, and single-line fields such as searches and passwords, are never read. There are no accounts and no tracking. The popup lists every proof made from this browser, with its link and its unique author code, which can take a piece down at any time; the site never keeps the code.
