Agentic AI search in millions of documents
Originally built for lawyers who deal with real complexity. At its core — agentic search: AI agents explore your documents on their own, search by meaning, cross-check results, and return an answer with references to the source.
It doesn't match keywords. It understands legal context: the relationships between concepts, the weight of a clause, the structure of an argument. What lawyers spent days on — done in minutes.
A lawyer doesn't have to take the system at its word. Every answer links directly to the exact passage — hover any reference to preview it on the spot, or open the full document in one click.
This matters most where the cost of error is high: in arbitration, litigation, compliance. The AI handles the search — the human stays in control of the conclusions.
NeedleSearch provides a REST API and an MCP server — connect search, chat, and deep research directly to your app or AI agent with a single API key. Python and JavaScript SDKs included.
Give your product the power of agentic research across millions of documents — without building the infrastructure. Your users get cited answers in seconds. You ship faster.
