Free AI search tools
No account, no card, no email. Each one answers a single question about how AI engines see your site, and each one gives you the whole answer rather than a teaser.

llms.txt Generator
Reads your sitemap, groups your pages into sections and drafts the file. Free, no account.
What the tools do not tell you
They cover whether the engines can read you. They do not tell you whether the engines name you when a buyer asks for a recommendation, or who gets named instead. Fulcru runs your buyer questions across ChatGPT, Perplexity, Gemini and Google AI Overviews every week and answers that. Compared against the alternatives, if you would rather read first.
