Last year we launched ChartDB OSS (https://news.ycombinator.com/item?id=44972238) - an open-source tool that generates ER diagrams from your database (via query/sql/dbml) without needing direct DB access.

Now we’re launching the ChartDB Agent.

It helps you design databases from scratch or make schema changes with natural language.

You can:

- Generate schemas by simply describing them in plain English

- Brainstorm new tables, columns, and relationships with AI

- Iterate visually in a diagram (ERD)

- Deterministically export SQL script

Try it out here - https://chartdb.io/ai - no signup required.

Or sign up and use it on your own database

Would love to get your feedback :)
