Question
Does Perplexity use llms.txt?
There is no public confirmation that Perplexity uses llms.txt as a retrieval input. Perplexity relies on its own crawl and index (PerplexityBot) plus live fetches (Perplexity-User). Treat llms.txt as a bonus source map, not a Perplexity channel.
What actually drives Perplexity citations
