Can AI assistants read archive.li?

Measured on 2026-09-19 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.

What each crawler got back

What to change, in order

1. Let in the 4 crawlers your own robots.txt already allows+4 crawlers
   ClaudeBot, GPTBot, OAI-SearchBot, PerplexityBot are turned away before reading the page (answered, but with far less text than a browser gets; answered with an HTTP error), while robots.txt permits them — so this block is not written in your site. No CDN signature was found in the response headers, so the refusal comes from the origin server itself or from a WAF this index does not recognise. Fixing it takes this domain from 0 to 4 of 4 crawlers.
2. Put the text in the HTML, not only in JavaScript
   The HTML that arrives is nearly empty and the content is painted by JavaScript. None of these crawlers run it, so even the ones that are served read a blank page. Server-rendering or prerendering the main content is what changes their result.
3. Declare the facts in JSON-LD
   There is no JSON-LD on the page, so every fact — who you are, what you sell, the price — has to be guessed out of the prose and the layout. A schema.org block is the difference between being quoted correctly and being paraphrased.
4. Publish llms.txt
   llms.txt is 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.
5. Fix the plain structure: one <h1>, a title, a description, alt text
   The structure check scores 50/100. These are the cheapest signals on the page and the first ones an assistant uses to decide what the site is.
