Your Professor's Lecture Has
No CaptionsNo Problem
NotebookLM only works if YouTube has captions. ChannelScout gets you the transcript regardless — then search it, clip it, or hand it off to any AI tool you already use.
No credit card. First transcript needs no signup.
The Caption Problem
Roughly 40% of YouTube videos have no caption track — including recorded lectures from older courses, visiting professors, conference talks, and creators who never enabled auto-captions.
Pulls YouTube's caption track. If it doesn't exist, you get:"Transcript not available for this video"No fallback. No workaround.
Falls back to Whisper AI — transcribes the audio directly at near-human accuracy. Works on any lecture, any language, any creator. You get the transcript.
The Student Workflow
ChannelScout is the extraction layer. It gets the transcript. Then it hands off to whatever AI tool you already use for deep Q&A.
Paste any lecture URL
YouTube, any professor, any channel — captioned or not. ChannelScout gets the transcript either way.
Search & clip what matters
Full-text search across every lecture you've saved. Clip the exact 90-second explanation for flashcards or study notes.

Built for Lecture Research
Works Even Without Captions
About 40% of YouTube videos have no caption track — including many recorded lectures, older uploads, and foreign-language courses. ChannelScout transcribes the audio directly using Whisper AI. NotebookLM returns an error. We return the text.
Clip Builder for Study Notes
Set A and B points around any lecture moment — a key definition, a worked example, a professor's summary — and download that exact clip. Shareable with your study group. No equivalent exists in NotebookLM.
Auto-Collect New Lectures
Follow a professor's YouTube channel and new lecture uploads appear in your library automatically every day. No manual pasting. Your transcript library grows while you sleep.

Permanent Transcript Library
Every transcript you extract stays in your library forever. Come back to a lecture a year later for citations or exam review — it's still there, still searchable.
AI Summaries per Lecture
Click Summarize on any transcript for a structured TL;DR, key takeaways, and notable quotes — powered by Claude AI. Great for building study guides quickly.
