The new part says models predict words rather than retrieve facts, and that all AI-generated content, metadata included, should be fact-checked by hand before publishing.

PerplexityBot and Perplexity-User: what each one fetches, and what the stealth crawling report means for your robots.txt

Perplexity documents two user agents. PerplexityBot indexes pages for Perplexity search and obeys robots.txt.

In August 2025 Cloudflare reported an undeclared crawler it tied to Perplexity, and Perplexity denied it.
