## At a glance

| Dimension | Exa | Tavily |
|---|---|---|
| Search architecture | Neural embedding search | Web search + LLM-curation |
| Result quality | Best for novel / semantic queries | Best for fact-finding |
| Content extraction | **Full-text + highlights + summaries** ✓ | LLM-summarized answers + sources |
| RAG-shape response | Built for retrieval pipelines | **Pre-summarized answer + citations** ✓ |
| Developer experience | SDK + clear docs | **Simplest one-shot API** ✓ |
| Pricing | Free tier + per-search paid | **Generous free tier + paid** ✓ |
| Latency | Sub-second typical | Sub-second typical |
| Use case | Agent research + semantic retrieval | Quick Q&A + agent tool |
| Best for | Semantic discovery, content-heavy pipelines | Fastest path to agent web search |

## 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.

## When to pick which

- **Exa** — Semantic / neural search, content extraction depth, research-style agents.
- **Tavily** — Plug-and-play agent search, generous free tier, RAG-shaped responses.
