Open-source database diagram editor with AI-generated ER diagrams
Paste a single read-only query result and ChartDB renders the whole schema as an ER diagram, with no direct database access or local agent required.
Describe a database idea in plain language and get a fully editable, optimized ER diagram that you can refine and export straight to SQL.
Export clean DDL scripts in your preferred SQL dialect or download diagrams as images and embeddable previews for documentation.
On Cloud plans, diagrams stay in sync with the live database automatically, with change logs and version history to track every schema drift.

Draft, summarize, translate, and answer questions inline, or build custom agents that automate recurring workflows around the clock.
Find answers instantly across Notion and connected apps, with citations so you can verify where each answer came from.
Use relations, rollups, views, and a large template gallery to model anything from a CRM to a content calendar.
