What you get in every set of notes
Chapter breakdowns
AI identifies natural topic boundaries and organizes the video into chapters with titles and start times — no manual scrubbing.
Core concepts
Each chapter surfaces the key ideas with plain-language explanations and evidence links to the exact second in the video.
Key terms and definitions
Important vocabulary is extracted with definitions grounded in what the speaker actually said — not invented.
Clickable timestamps
Every concept, term, and quiz answer links to the source moment. Click to open YouTube at the exact second.
Why timestamped notes beat plain summaries
You can verify everything
Every claim links to the source. If the AI got something wrong, you can check the original moment in one click.
You rewatch what matters
Instead of re-watching a 40-minute lecture, jump straight to the 30 seconds where a concept was explained.
You study actively
Notes pair with a practice quiz and flashcards, so you test yourself instead of passively re-reading.
