Introduction
Search the web like a database.
Dataembed is an alternative to Exa Websets, built by Kaiyu Hsu. You describe what you're looking for in plain English — "YC companies building dev tools for Postgres" — and a durable agent turns it into a webset: a structured table of real web entities, each row verified against your criteria (with verbatim evidence quotes) and enriched with extracted data columns.
Under the hood, one run means: plan search queries + criteria + columns, fan each query out across every configured search provider, merge the ranked lists, then fetch and verify every candidate page with an LLM. Rows stream into your table live as they complete. See How it works for the full pipeline.

No account needed. Go to the homepage, type a query, and watch the webset build. Anonymous sessions are capped at 3 websets per hour (per IP), 3 search queries, and 10 results per webset — sign up to raise the caps to 6 queries and 25 results.
Export any webset as CSV or JSON from the results page, or via the REST endpoints.
