Assay

Answers with receipts, or no answer at all.

What it does

Ask a question over a set of documents, like company annual reports or internal policies, and get an answer where every claim cites the passage it came from. If the documents can’t support an answer, it says so instead of guessing.

Who it’s for

Teams that can’t afford an AI that makes things up: legal, compliance, finance, support.

How it’s built

Hybrid search over Postgres, Claude for answers, and a second model that checks every citation before you see it. A scored evaluation suite runs on every change and blocks any release that makes answers less grounded. Once you have access, any AI client can connect to it through its MCP server.

Built with

  • PostgreSQL
  • Hybrid search
  • Claude
  • MCP server
  • Eval suite

Key decisions

Refuse rather than guess. A strict check blocks any answer the documents can’t back up, and the evaluation gate blocks any release that would weaken it.
