querion

Querion answers plain-English questions about a Postgres database and read-only web application programming interfaces (APIs). Each reply carries the number, a table, a chart when one helps, and the Structured Query Language (SQL) it ran, so the answer can be checked. It is built only to read. Give it a read-only database role and read-only API tokens, and a mistake cannot change your data. It runs on your local Claude Code command-line interface (CLI), with no API key to manage.
