Thanks! We have tried to make Ragnerock almost a drop-in replacement for Jupyter Lab's frontend, with some additional features to make it easy to pull in query results and run AI coding assistants directly in the notebook.

Yes, you can use your AI & DB with the 20 hours of compute. To use your existing AI provider just put the credentials (API key), model version, and endpoint in the AI config in the settings menu (lower left button -> settings -> AI). If you're just kicking the tires, you don't need to provide these integrations though (Ragnerock will use our Gemini endpoint by default).
