The pitch

No more NotebookLM.

Here's why. NotebookLM locks your sources in Google Drive, has no offline story, and can't touch the markdown vault you already keep. Sanji is the opposite of every one of those.

NotebookLM

✕Sources locked into Google Drive
upload-only, not your filesystem

✕Cloud-only, no offline mode

✕Closed source, your data is theirs

✕Per-use limits on Google's terms
