Chion vs SQLAI.ai

Chion turns plain-English questions about PostgreSQL into code-validated, read-only SQL and interactive D3 charts, displaying the SQL beneath each chart. It 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 execution. Results are limited to 1,000 rows or 12,000 cells. Eight built-in chart types include line, area, bar, and animated bar-race formats. Saved queries can become portable SQL skill files for Claude Code and Codex. Chion runs in the cloud through the web. Starter costs $29/seat/mo, Pro $99/seat/mo, and Max $299/seat/mo, each with a seven-day trial; Enterprise uses custom per-team pricing. Credentials are encrypted in an AES-256-GCM vault, while Chion says it is not SOC 2 certified and does not support HIPAA workloads.

SQLAI.ai is a web and API toolbox for generating and working with SQL and NoSQL queries. Its text-to-SQL generator turns plain-language requests in many languages into queries; other tools optimize, validate, format, explain, and convert them. The SQL optimizer offers index-aware rewrites and explains performance changes. Database rules, schema autosuggest, a VS Code-style editor, side-by-side diff view, and large-schema support provide additional query tools. Its directory lists 28 database engines, including MySQL, PostgreSQL, SQL Server, Oracle PL/SQL, and MongoDB; some support live connections and others schema-only workflows. Users can run natural-language queries against connected databases, and the site recommends read-only connections for improved security. The company says it stores schemas rather than actual database data and encrypts credentials routed through a proxy. The public API uses an access token in a request header; API requests cost 3 credits per query or 5 for very large schemas. Hobby costs $4 a month and includes 50 queries per month; a 7-day trial is listed, but no free plan.
