Tavily
Tavily returns structured snippets and optional images so LangChain-style agents can cite fresh web data—built for builders wiring RAG or autonomous research loops, not casual chat.
Glean
Glean indexes Slack, Drive, Jira, and hundreds of other systems with ACL awareness so employees get answers that respect real access rules—not a naive crawl of everything.
Perplexity
Perplexity blends conversational prompts with live search, pulling citations into the reply so you can verify claims quickly—Comet and enterprise tiers push toward actionable follow-ups.
