Can AI assistants read coursera.org?

Measured on 2026-09-20 by asking the site 9 times — once as a browser, once as each of the 8 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 #1,201.

A91 / 100
7 of 8 crawlers can read this page.

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

  1. 1 crawler is named and refused in robots.txt — a deliberate choice
    Meta-ExternalAgent is blocked by a rule that names it. Nothing to fix here: this page records what is true, not what should be. It is listed so the deliberate part of the block is not confused with the accidental part above.

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

coursera.org AI readability: A 91/100 
<a href="https://aivis.lumnika.com/ai-readiness/coursera.org"><img src="https://aivis.lumnika.com/ai-readiness/coursera.org/badge.svg" alt="AI readability"></a>
Method. 9 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.
