llms.txt Health Report

Scan any site for AI readability and catch fake llms.txt files

Problem

Someone scanned 1,000 Chinese sites and found only 3% had a real /llms.txt. 164 returned HTTP 200 but were just HTML shells, 412 were 404, and the rest were blocked or timed out. Site owners think they are AI-ready, but AI crawlers get nothing but shells.

Solution

Enter a domain and get an automatic report on /llms.txt presence, reachability from major AI crawler user agents, page text quality, and structured data quality, with a score and fix suggestions. Scheduled rescans and change alerts keep the site honest over time.

Users

SEO and growth leads, indie site owners, corporate website operators, AI product teams

MVP

Single-page web tool; fetch llms.txt and classify real file / HTML shell / 404; reachability test with major AI crawler UAs; score plus 3-5 fix suggestions; PDF export

Revenue

Free one-off scan, subscription for batch monitoring, scheduled rescans, and change alerts ($19-99/mo by domain count)

Why now

AI crawlers are becoming a major traffic source, yet site owners have almost no observability into AI readability and big tools have not covered this niche
