What Chion is
Chion turns plain-English questions about PostgreSQL into code-validated, read-only SQL and interactive D3 charts, with the SQL displayed under each chart. It connects directly to PostgreSQL without ETL or a warehouse copy, and lists Amazon RDS, Azure Database for PostgreSQL, Google Cloud SQL, Neon, Supabase, and self-hosted PostgreSQL as connection options. Validators reject statements other than read-only SELECT queries before they reach the database; results are capped at 1,000 rows or 12,000 cells. The service includes query explanations and schema context, and offers eight chart formats, including line, area, bar, and animated bar-race charts. Saved queries can be compiled into portable SQL skill files for Claude Code and Codex. Chion is a cloud service for the web. Starter costs $29 a month per seat, Pro $99 a month per seat, and Max $299 a month per seat; each includes a 7-day trial. Enterprise pricing is custom per team. Chion says database credentials are encrypted and notes it is not SOC 2 certified or intended for HIPAA-covered workloads.
