# Which AI agents does Lalela detect?

From How it works, “Types of AI agent traffic”:

> - **User-triggered fetches:** an assistant fetches a page because a person asked it something just now. Examples: ChatGPT-User, Claude-User, Perplexity-User. These are the most valuable visits.
> - **Agentic browsers:** an AI agent drives a browser to complete a task such as comparing products or signing up.
> - **AI search indexers:** crawlers that build the indexes AI assistants search, such as OAI-SearchBot, Claude-SearchBot and PerplexityBot.
> - **Training crawlers:** crawlers that collect pages for training models, such as GPTBot and ClaudeBot.
> - **AI referrals:** people who click through to a site from an AI assistant's answer.
