Verdict
Exa is the right pick for agents doing semantic discovery, content-heavy research pipelines, or anywhere keyword search misses (novel queries, recommendation-style retrieval). Tavily is the right pick for the fastest path to working agent search — one API call returns an LLM-summarized answer with citations, ready to feed into the next agent step. Many production agents use Exa for deep research + Tavily for fact-checking.
