Features
Everything you need to feed Gemini Notebook
Fifteen capabilities, one free extension. Every feature rides on your existing Google login, no extra account required.
⌨️ Quick-save shortcut
Ctrl+Shift+S sends the current page directly to your last-used notebook. No popup, no prompt, instant.
🖱️ Right-click menu
Add a page, selection, link or image to Gemini Notebook by right-clicking. Selections become text sources; everything else becomes a web source.
🗂️ Full-page dashboard
A dedicated dashboard with seven sections: overview, notebooks, all sources, import, audio overviews, prompt library, and settings. Grid and table views, search, and sorting included.
📥 Bulk URL import
Paste a list of URLs or pick from links detected on the current page, then import them into a notebook in batches with live progress.
📡 RSS and Atom feed import
Deftery auto-detects feeds on the current page or accepts a feed URL directly. Pick the items you want and send them in one click.
▶️ YouTube video in one click
On every YouTube watch page Deftery places a “→ Gemini Notebook” button next to Like and Share. One click adds the current video as a source.
📺 YouTube channel in one click
On a channel’s Videos tab the same button sits next to Subscribe. It scrapes every listed video (up to 500) and imports them in a single batch.
🎬 YouTube playlist import
On a playlist page open the popup and add every video in the playlist as a Gemini Notebook source with one button.
📚 Notebook management
List, create, and delete notebooks from inside the extension, now with a full source detail view in the dashboard. The list is cached locally so the UI stays responsive.
⭐ Local organization
Favorites, tags, and folders for your notebooks plus a personal prompt library. All assignments stay entirely on your device.
🎧 Audio overviews
Generate audio overviews from inside the extension, listen to them in the gallery, and export them as a podcast RSS feed for any podcast player.
✨ Optional on-device AI
If you opt in, the AI built into your browser suggests the right notebook, titles text sources, and makes a smart link selection during bulk import. All processing runs entirely on your device.
👥 Multiple Google accounts
If you use several Google accounts in the same browser profile, Deftery sets the account index so it talks to the right Gemini Notebook instance.
🌐 Fifteen UI languages
15 languages, including Arabic and Hebrew with right-to-left rendering. Defaults to your browser language and can be overridden in Settings.
🔒 Privacy first
No analytics, no telemetry, no third-party calls. Your settings live in your browser, never on minoka servers.

Frequently asked questions
Frequently asked questions
Everything you may want to know before installing.
What does Deftery cost?
Deftery is free. There is no paid tier, no advertising, no PRO upsell, and no usage limits. minoka.de keeps Deftery free as a utility for the Gemini Notebook community.
What happened to NotebookLM?
Google renamed NotebookLM to Gemini Notebook in July 2026. The application itself is still available at notebooklm.google.com; only the name changed. The extension is therefore now called Gemini Notebook Clipper – Deftery and works exactly as before.
Do I need a Gemini Notebook API key?
No. Gemini Notebook does not offer a public API. Deftery uses your existing Google session in the same browser profile to talk to Gemini Notebook on your behalf.
Which browsers are supported?
Every Chromium-based browser: Google Chrome, Microsoft Edge, Brave, Arc, and similar. Built on Manifest V3, so future-proof.
What data does Deftery collect?
None. Deftery contains no analytics scripts, no telemetry, and no third-party calls. Settings, your last-used notebook, your local organization, and the language choice live locally in your browser. The optional on-device AI also processes content entirely on your device. Details are in the privacy policy.
Which permissions does Deftery request?
activeTab, contextMenus, storage, and tabs. Plus host permissions for notebooklm.google.com and *.youtube.com. Every permission has a clear purpose, documented in the privacy policy.
What can the dashboard do?
The dashboard is a full-page view with seven sections: overview, notebooks, all sources, import, audio overviews, prompt library, and settings. You open it through the “Dashboard” button in the popup. Notebooks can be shown as a grid or a table, searched, sorted, and opened with a full source detail view.
How does the optional on-device AI work?
If your browser supports the built-in local AI, Deftery can suggest the right notebook for the current page, title text sources automatically, and separate navigation links from content links during bulk import. All processing happens entirely on your device, no content is sent to any server, and no API key is required. If the local AI is not available, Deftery simply hides these features.
What does Deftery do on YouTube pages?
Deftery places a small “→ Gemini Notebook” button into YouTube’s existing actions row: on every watch page next to Like and Share, on a channel’s Videos tab next to Subscribe. One click sends the current video or every channel video to your last-used notebook. On playlist pages Deftery detects the list as soon as you open the popup. No additional request is made to YouTube; Deftery only reads the page you are already viewing.
Does Deftery work with multiple Google accounts?
Yes. In Settings you can pick the account index (0 for the first account, 1 for the second, and so on). Deftery then talks to the Gemini Notebook instance of the matching account.
Which UI languages does Deftery support?
Fifteen: English, German, Turkish, French, Spanish, Italian, Dutch, Polish, Japanese, Korean, Russian, Brazilian Portuguese, Simplified Chinese, Arabic, and Hebrew. Arabic and Hebrew render right-to-left. Defaults to your browser language and can be overridden in Settings.
What happens when Gemini Notebook offers an official API?
As soon as Gemini Notebook ships a public API, we migrate the extension onto it. The switch is invisible to you and changes nothing about the features.
How do I activate Deftery for my workflow?
After install, open the popup once, pick a notebook as the default, and close the popup. The keyboard shortcut Ctrl+Shift+S and the right-click menu work from then on.
Where do I find help?
The dashboard’s Settings section has a “How to use” area that explains every feature. For other questions, reach minoka.de through the contact page.
