Chion
Broward County, Florida, United States
What it is
Chion is a paid web service that turns plain-English PostgreSQL questions into code-validated, read-only SQL and interactive D3 charts. The generated SQL appears below each chart. Chion connects directly to PostgreSQL without ETL or a warehouse copy, supporting Amazon RDS, Azure Database for PostgreSQL, Google Cloud SQL, Neon, Supabase, and self-hosted PostgreSQL. Validators reject statements that are not read-only SELECT queries before database access. Results are limited to 1,000 rows or 12,000 cells. Eight listed chart types include line, area, bar, and animated bar-race formats. Saved queries can be compiled into portable SQL skill files for Claude Code and Codex. Database credentials are kept in an AES-256-GCM vault, with plaintext held for at most 60 seconds or five reads before purging. Chion says the model receives the question, schema names, narrative result rows, and sampled column values. Starter costs $29/seat/mo, Pro $99/seat/mo, and Max $299/seat/mo; each includes a seven-day trial. Enterprise is custom per team.
