Hey HN, my name is matt. I built "i typed it" as a platform agnostic proof for human typed text. I've been frustrated recently by posts and comments (on hn and elsewhere) that feel obviously ai generated. I don't mind using AI to brainstorm/edit/revise, but it's a bit painful when it seems like a human didn't even bother reading it before positing.

The tool today measures high level signals (typing consistency, paste %, edit rate ,etc.) to give a score. After writing your message you save an attestation link and include it in the post/comment. This basic approach is deeply flawed, but hopefully better than nothing. I'm curious what current state of the art is for _guaranteeing_ that something is human typed. Perhaps some sort of hardware integration?

I'm working on a browser extension, and a quick way to integrate attestations with comment sections so users don't need to include the link copy/pasted. Would love any and all feedback.
