Context Listener 是什么
Live AI notes, transcripts & stock cards for any video or podcast — built for students, investors & researchers. Live AI notes, transcripts, and entity cards that appear in your sidebar as you watch — without pausing, scrubbing, or copy-pasting transcripts into ChatGPT, Claude, Gemini, or Grok.
Context Listener listens to any audio playing in your browser and explains people, companies, stocks, and concepts in real-time. The only AI notes tool that works LIVE — not after the video ends.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🎓 FOR STUDENTS & LIFELONG LEARNERS Turn any lecture, YouTube explainer, or educational podcast into study-ready notes. Concepts are defined as they're mentioned. Key takeaways and techniques are extracted automatically. Export study guides to clipboard or file.
📈 FOR INVESTORS & FINANCE NERDS Watching finance YouTube, earnings calls, or investing podcasts? Live stock cards pop up the moment a ticker is mentioned — with real-time prices, 52-week ranges, and daily change. Never pause to look up a company again.
🎧 FOR PODCAST LISTENERS & RESEARCHERS Get a live transcript with every person, company, and concept highlighted. Click any entity for an instant explainer. Review past sessions anytime in your history.

WHY DOES CONTEXT LISTENER NEED "ALL WEBSITES" PERMISSION? Context Listener works on any tab playing audio — YouTube, podcasts, Zoom, lectures, livestreams, news sites. Chrome's permission system requires "all websites" access for the extension to detect audio across any site you use. Context Listener never reads page content beyond what's needed to capture audio for transcription.
