Perplexity

PerplexityBot, Perplexity-User

Perplexity is an AI “answer engine”: it searches the web and writes an answer with links. PerplexityBot indexes pages; Perplexity-User fetches a page when someone's question needs it.

Worth knowing: in 2024 and 2025 journalists and Cloudflare said Perplexity also read pages that had blocked it, using visitors that didn't give its name. Perplexity disputed this.

Why? Writing and pictures are the raw material for training AI models, and AI search and assistants fetch pages to answer people’s questions. The answer is given inside the chat, so the person asking often never comes to the site itself.
