Shelfy — Folders for NotebookLM

Folders and sub-folders for your NotebookLM notebooks. Your structure is stored locally and never lost.

Shelfy adds one thing to NotebookLM, and does it right: folders. ORGANIZE • Create folders and sub-folders, right in the NotebookLM home page • Drag and drop notebooks into folders — or right-click → "Move to" if you prefer • New notebooks land in "Unfiled" automatically, so nothing slips through • Instant search across your notebook titles • Works in grid view and list view, follows NotebookLM's light/dark theme YOUR STRUCTURE IS NEVER LOST Other folder extensions store your data in Chrome's sync storage, which has a 100 KB quota and merge conflicts — that's how people lose their folders. Shelfy is built the opposite way: • Everything is stored locally in your browser (chrome.storage.local — no quota issues) • Every change is journaled before it is written: an interrupted save can't corrupt your data • Automatic weekly snapshots, kept for 4 weeks • One-click JSON export and import for manual backups MINIMAL PERMISSIONS — BY DESIGN Shelfy only asks for access to notebooklm.google.com and local storage. No "read all your tabs". No account. No server. Your data never leaves your browser. FREE VS PREMIUM • Free: up to 5 folders — forever • Premium (one-time purchase): unlimited folders, sub-folders, and more to come Shelfy is not affiliated with Google.
