The honest brief

Exa

Built for AI/research retrieval: neural embedding search plus find-similar, where general search APIs key off keywords.

  • Semantic 'find pages like this' retrieval
  • Purpose-built for RAG and agents
  • Returns full page content, not just links
  • Free tier to test
  • Index narrower than Google-scale crawlers
  • Keyword queries can lag classic search
  • Usage-priced costs scale with volume

Perplexity

Pairs a consumer cited-answer engine with the Sonar API, so the same retrieval layer powers both.

  • Inline citations on synthesized answers
  • Cited search API for your own apps
  • Pro lets you pick a model per query
  • Strong on fresh, fact-based queries
  • Citations can misattribute or be wrong
  • Weak on niche topics with thin sources
  • Best features gated behind Pro
