What it takes to run
Docker is the first hurdle, followed by supplying at least one provider API key or setting up Ollama and assigning models to the required roles
Where your data lives
Uploaded sources, generated audio, and checkpoints live in the mounted ./data directory, while notebook records and indexes live in the mounted SurrealDB data directory
Why fork Open Notebook instead of vibe-coding a Lateral clone?
The visible research workspace loop is buildable, but a credible replacement needs more than the first screen. Lateral earns its keep through data, import reliability, so expect a weekend or multi-day build and a narrower personal scope.
