Deep Dive: Switching from Saner.AI to Open Notebook
Trade-offs, installation & data architecture
What you trade away
It is an upload-first source notebook, so quick capture, automatic connections, and everyday personal-knowledge workflows are weaker than Saner.AI's.
How to deploy Open Notebook
Download the official Docker Compose file, set an encryption key, and start the Open Notebook and SurrealDB containers
What it takes to run
Docker and 4 GB RAM are required, and the user must replace default secrets then configure at least one model provider or add an Ollama container
Where your data lives
Notebook metadata, notes, source records and encrypted provider credentials live in the self-hosted SurrealDB; uploaded source files live in the mounted notebook_data directory, with selected context sent to any cloud AI provider used
Why fork Open Notebook instead of vibe-coding a Saner.AI clone?
The visible AI personal knowledge loop is buildable, but a credible replacement needs more than the first screen. Saner.AI earns its keep through polish, sync, importers, so expect a weekend or multi-day build and a narrower personal scope.
