  description

  You're reading a great article. You want to save it to NotebookLM. So you open a new tab, navigate to NotebookLM, find the right notebook, paste the URL, and switch back — and now you've lost your place.
  
  Kaptex fixes this. It sits in a persistent side panel so you can add any source to NotebookLM without leaving the page you're on. One click. Done.
  
  
  📺 YOUTUBE TO NOTEBOOKLM
  
  Watching a video you want in NotebookLM? Hit the "Add to notebook" button on the player. No tab-switching, no copy-paste — it's in your notebook before the video ends.
  
  
  🎯 ONE-CLICK CAPTURE ON YOUR FAVORITE PLATFORMS
  
  Kaptex adds a 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 videos — add any video without leaving the player
  👽 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

  📋 Paste a list of URLs and send them all in one go
  🧠 Import every open tab with a single click
  ✅ Select all or pick and choose before sending
  
  
  🗂 NOTEBOOK MANAGEMENT

  🆓 FREE AND PRO
  
  Free plan: 10 captures per day — enough to try every feature.
  
  Pro plan: Unlimited captures, unlimited bulk imports, and notebook creation from the panel. For serious researchers, students, and creators who need it all.
  
  
  WHO IS KAPTEX FOR?
  
  🎓 Students — you have 12 browser tabs open and an essay due tomorrow. Clip every source into NotebookLM in seconds, so you can actually start writing.
  
  🔬 Researchers — stop breaking your reading flow to file sources manually. Capture anything while you keep reading.
  
  🎥 Content creators — your best ideas come from across the internet. Give them a home in NotebookLM before you forget them.
  
  💼 Professionals — feed market research, reports, and links into NotebookLM for faster analysis. No tab-juggling required.
  
  
  🔒 PRIVACY
  
  Kaptex uses Google sign-in. Only your notebook metadata and daily usage counts are stored in your account. No browsing history is collected and no page content is scraped in the background.
  
  
  Add anything to NotebookLM without switching tabs. Install Kaptex — it takes 30 seconds to set up and works everywhere you already research.

  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.
