Agent-Readiness Assessment
Check what an AI assistant can read on your site, scored across six dimensions, in about 30 seconds.
Free tools
Tools we built, free to use
These are the utilities we reach for during an audit. They run entirely in your browser, so nothing you paste is uploaded, stored, or logged, and there is no signup or usage limit to work around.
If you came here to see what we do rather than to decode a token, start with the free Assessment below. It reads your site the way an AI assistant would and tells you what it found.

Where the audits come in
We keep these online because they are useful, and because they give you some idea of how we work before you have paid us anything. The audits are the paid side of the same practice: the same attention applied to your whole site, written up in a report you can hand to your developers.
