Save anything to NotebookLM — one click from any tab. Save anything to NotebookLM — capture, import, and generate — all from one side panel.
You're deep in research. You find the perfect article, Reddit thread, or YouTube video. Getting it into NotebookLM means opening a new tab, navigating to the right notebook, and losing your place. Then, once it's there, generating a summary or audio overview means another round of navigation.
Kaptex removes that friction entirely. A persistent side panel that lets you add sources and trigger Studio generation without leaving whatever you're doing.
One click. Back to work.
📺 YOUTUBE SUITE — NOT JUST SINGLE VIDEOS
Kaptex handles the entire YouTube research workflow:
📺 Add any video directly from the player 📋 Import an entire playlist — select all or pick specific videos 🔍 Search YouTube from the Kaptex panel, set a result limit, and add what you find — without visiting YouTube.com 📡 Paste a channel URL or @handle and pull the latest videos from any creator or course series
Ideal for lecture series, research playlists, and channels you follow regularly.
🤖 GENERATE FROM THE SIDE PANEL — STUDIO
No other NotebookLM extension does this.
Once your sources are in, Kaptex lets you trigger generation directly from the panel — without navigating into the notebook:
🎙️ Audio Overviews — generate a podcast-style summary of your notebook 📊 Infographics — create visual summaries from your sources 📝 Reports — generate structured text summaries 📑 Slides / Presentations — create slide decks ready for export
Pick a notebook. Choose what to generate. Done. The result appears in NotebookLM as normal.
🎯 ONE-CLICK CAPTURE ON YOUR FAVORITE PLATFORMS
Kaptex adds a capture button directly inside the sites you already use for research:
💬 ChatGPT — save full AI conversations as a cited NotebookLM source 🤖 Claude — archive your Claude sessions with a single click 🔎 Perplexity — capture AI research threads instantly 📺 YouTube — send any video straight from the player 👽 Reddit — pull the full post plus top comments in one action
The button reads the page context automatically and routes content to your selected notebook.
📥 EVERY SOURCE TYPE, ONE PANEL
🌐 Web URLs — paste any link or use "current tab" for instant capture 📺 YouTube — single videos, playlists, channel pages, or in-panel search results 👽 Reddit threads — fetch structured posts and top comments with full context ✂️ Text snippets — highlight any text on a webpage and clip it into the panel 📝 Custom text — paste notes, transcripts, or prompts with a custom title 📂 Local files — upload notes, transcripts, data files, or research docs (.txt, .md, .csv, .html, .json)
⚡ BULK IMPORT

More than just capture — Kaptex handles the full source and notebook workflow:
📋 Browse all notebooks and their sources without opening NotebookLM 🗃️ Copy or move sources from one notebook to another 📌 Duplicate any shared or featured notebook so you can edit it, add sources, and generate from Studio — shared notebooks are read-only, Kaptex breaks that wall 🗑️ Remove sources from the panel ➕ Create new notebooks (Pro)
