What it is

Exa is a developer-facing search engine: an API that returns semantically relevant web pages, extracted page text and research-agent runs, plus Websets for building lead and research lists. Billing is usage-based with a free monthly credit allowance and no seat pricing. It is a developer product, so non-technical users will need an integration (MCP server, ChatGPT plugin or a partner app) rather than a ready-made search interface.

Standout capability

Embeddings-based search that returns full page contents in one call, tuned for LLM pipelines.

Community sentiment

What people praise

Developers like that results come with relevance scores and page text in a single call, and that keys, SDKs and rate-limit headers make it quick to wire into an agent.

What people complain about

Reviewers note that semantic search can underperform plain keyword search on narrow technical queries and that highlights are not always accurate.
