If you want to turn any lecture video into clean notes (and diagrams) in minutes, start with WhispriNote and paste a link into YouTube-to-notes.
This post lists strong lecture channels by subject, then shows the exact workflow to study from them.
Quick verdict (2026)
- Use "structured lecture" channels (full lessons, playlists, courses) for serious studying.
- Turn each video into a one-page revision sheet: headings → 3-6 bullets → key terms → practice questions.
- Add one visual (mind map / flowchart / timeline) for the hardest section.
- For longer videos, visual notes, PDF exports and voice chat with your notes, check pricing.
At a glance: great channels by subject
| Subject | Channels to try | Best for |
|---|---|---|
| General study | Khan Academy, CrashCourse | Clear fundamentals + exam review |
| University courses | MIT OpenCourseWare | Full-length lecture series |
| Math | 3Blue1Brown, Professor Leonard | Concept intuition + long lectures |
| Computer science | CS50, freeCodeCamp.org | Intro courses + practical projects |
| Physics | Walter Lewin Lectures (MIT), Khan Academy | Problem solving and intuition |
| Biology/medicine | Amoeba Sisters, Ninja Nerd | Processes and high-yield review |
| Chemistry | The Organic Chemistry Tutor | Worked examples + practice |
| Economics | Marginal Revolution University | Models explained simply |
Note: channel availability changes over time, and some topics are split across multiple playlists. Use this list as a starting point, then follow the workflow below.
