Free tools
Two free tools, no account, nothing uploaded
Both run entirely in your browser. We do not receive your answers, we do not store them, and there is no form handler behind either page — which is the only honest way to offer a free tool that asks a business to type out its own facts.
llms.txt generator
Answer the questions buyers ask and get a valid file: Markdown, level-one heading first, real Markdown links, a named sign-off and a version. It emits the same format our paid engine emits — the form’s labels are read from the same schema file, and the build refuses to ship if the two drift apart.
llms.txt validator
Paste a file you already have. Every check names its authority: the conditions Google’s agent-readiness audit applies, the format the specification describes, or something we measured ourselves. Paste-in only, and the page explains why that is the honest shape for it.
why these are free
Because the file is the easy part
The fact sheet is one of eight surfaces in the paid package, and on the evidence it is the weakest of them as a mechanism: agents given no pointer to it opened it 0 times in 18 visits (Note 15), and in a census of nine real sites, seven published one and none placed it where it gets read (Note 09). It passes an audit — the package passes Google’s agent-readiness audit — and it does not answer a buyer.
So we give away the part that is easy to automate and charge for the part that was measured: the homepage fact block, which recovered 78% of fact checks against 30% in the control with agents stopping after 1.1 pages on average (Note 41), plus the before-and-after audit that shows whether it worked on your site specifically.

Generating the file takes two minutes. Finding out what a model can recover from your homepage takes one request.
One model fetches your homepage and answers buyer questions from it. You get the recovery score and the specific answers it could not find. That is the whole free tier: it shows you the problem, and the fix package is not included.
