Can AI assistants read intellij.net?

Measured on 2026-09-15 by asking the site 5 times — once as a browser, once as each of the 4 crawlers that feed ChatGPT, Claude, Perplexity, Gemini, Meta AI, Apple Intelligence and Doubao — and comparing what came back. The AI-training opt-out tokens that never crawl are read from robots.txt instead. Tranco rank #10,173.

B82 / 100

4 of 4 crawlers can read this page.

More readable than 67% of the 47,934 sites measured so far. Structured data: WebPage, SoftwareApplication.

What each crawler got back

Google-Extended (Gemini, AI Overviews) a robots.txt token, not a crawler: it controls how already-crawled pages may be used, and never makes a request of its own	—	not opted out	no-rule

AWS CloudFront answers for this domain. Where a crawler above is refused while robots.txt allows it, the rule is applied by that edge, not written by the site — see how often each edge does this.

What to change, in order

Publish sitemap.xml and llms.txt
sitemap.xml and llms.txt are missing, so an assistant has to discover the site by following links. llms.txt is the emerging convention for telling an assistant which pages actually matter.

Get told if this changes

One email only when a measured crawler flips on intellij.net, served to refused or back. No schedule, no newsletter; double opt-in, one-click stop.

Method. 5 live HTTP requests (one per crawler, one as a browser) plus robots.txt, llms.txt, sitemap.xml and security.txt, 12-second timeout each, from a single vantage point. Blocking AI crawlers is a legitimate choice, not a failure: this page records what is true, not what should be. Domain comes from the Tranco research list. One page per domain — the homepage — is audited.
