Chion vs NatureQuery

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.

NatureQuery turns natural-language questions into SQL, runs them against a connected database, and exports results as Excel spreadsheets or CSV files. Its AI is described as understanding database schemas, and the product can create bar, line, and pie charts from results. Listed database support includes PostgreSQL, MySQL, SQLite, SQL Server, MariaDB, and Amazon Redshift. Teams can invite members and share connections and saved queries using role-based access. The cloud service is available through the web and API. Its free plan costs nothing and includes 50 queries per month, one database connection, and 30 days of query history. Pro costs $20 a month and includes unlimited queries, 10 connections, collaboration for five members, API access, and priority support. Enterprise costs $79 a month and lists unlimited queries, connections, and members, plus SSO / SAML, audit logs and compliance, and dedicated support with an SLA. NatureQuery says credentials and connections are encrypted and query results are not stored.
