Gemini Notebook Clipper - Deftery Chrome extension security report

Deftery — Save anything to Google NotebookLM in a single keystroke. NotebookLM Clipper - Deftery is a free Chrome extension that pushes web content directly into your Google NotebookLM notebooks. No copy-paste, no detour through a "saved clips" folder, no waiting for a public API. Deftery talks to NotebookLM the same way the NotebookLM web app does and adds your sources where they belong. WHY DEFTERY? Researchers, writers, students, and knowledge workers who use Google NotebookLM as a thinking environment know the pain: every interesting page, article, or video has to be opened in NotebookLM, pasted as a source, named, and saved — one at a time. Deftery removes the friction. One keystroke or one right-click sends the page straight to your last-used notebook. WHAT IT DOES 1. Quick-save shortcut Press Ctrl+Shift+S (Windows / Linux) or Cmd+Shift+S (Mac) to send the current page directly to your last-used NotebookLM notebook. No popup, no prompts, instant. 2. Right-click menu Right-click any page, selection, link, or image and send it straight to NotebookLM. Selections become text sources, everything else becomes a web source. 3. Popup capture Click the toolbar icon to see page metadata, the current selection, detected RSS feeds, page links, and YouTube playlist info — then pick a notebook and send. 4. Bulk import Paste a list of URLs (one per line) or pick from links detected on the current page, then import them all into a notebook in batches. Filter by YouTube, PDF, or external links. 5. RSS feed import Deftery auto-detects RSS and Atom feeds on the current page or accepts a feed URL directly. Pick the items you want and import them as NotebookLM sources in one click. 6. YouTube one-click on every page On any YouTube watch page Deftery injects a "→ NotebookLM" button next to Like and Share — one click adds the current video as a NotebookLM source. On a channel's Videos tab the same button sits next to Subscribe and imports every video on the channel (up to 500) in one batch. On a playlist page open the popup and use "Import Playlist Videos" to push the entire playlist. 7. Notebook management List, create, and delete NotebookLM notebooks from inside the extension. Notebooks are cached locally so the UI stays responsive even when the API is briefly unreachable. 8. Audio overview trigger Generate NotebookLM's audio overviews from the Notebooks tab. Export saved overviews as a podcast RSS feed for any podcast player. 9. Multi-account support Multiple Google accounts? Switch the Google account index in Settings — Deftery talks to the right NotebookLM instance. 10. 8 UI languages English, German, Turkish, French, Spanish, Italian, Dutch, Polish. The popup uses your browser language by default and can be overridden manually in Settings. FREE FOREVER Deftery is free. No paid tier, no PRO upsell, no in-extension purchases, no ads, no usage limits, no telemetry. It stays free because minoka.de builds it as a utility for the NotebookLM community. PRIVACY-FIRST Deftery does not track you. No analytics scripts, no usage events, no third-party calls. The only servers Deftery contacts are: - notebooklm.google.com — to send your sources to NotebookLM (uses your existing Google login) - youtube.com — to read playlist video lists when you import a YouTube playlist - RSS feed URLs you explicitly choose to import Your settings, last-used notebook, and language override live in chrome.storage.local on your own machine. Nothing is shipped to minoka.de. Read the full privacy policy at https://minoka.de/deftery/datenschutz/ (DE) or https://minoka.de/en/deftery/privacy/ (EN).
