Turn any math YouTube lecture into searchable notes instantly
Or just change youtube.com to 2outube.com in your browser
To transcribe a math YouTube video, replace 'youtube.com' with '2outube.com' in the URL. You instantly get the full transcript—perfect for capturing equations, proofs, and step-by-step explanations from calculus, algebra, and statistics lectures.
The Trick
youtube.com/watch?v=VIDEO_ID
2outube.com/watch?v=VIDEO_ID
Just change 'y' to '2'
Works with any YouTube video that has captions
Top Mathematics YouTube Channels to Transcribe
3Blue1Brown
Visual, intuition-first explanations of linear algebra, calculus, neural networks, and number theory using animated 'manim' graphics.
Khan Academy
Comprehensive K-12 through college-level math covering arithmetic, algebra, geometry, trigonometry, calculus, and statistics.
Professor Leonard
Full university-level calculus, differential equations, and statistics courses taught in real classroom sessions, often 2–3 hours long.
blackpenredpen
Fast-paced calculus, differential equations, and competition math problems solved live with black and red markers.
Best Practices for Mathematics Video Transcripts
Use Ctrl+F to jump to specific concepts
Once you have the transcript open, search for terms like 'derivative,' 'eigenvalue,' or 'proof by induction' to skip directly to.
Supplement with your own notation
Math transcripts capture spoken words, not symbols. Paste the transcript into your notes app and manually add LaTeX or standard.
Transcribe worked examples, not just definitions
The highest-value content in math lectures is the step-by-step problem walkthrough.
Compare transcripts across multiple instructors
The same topic—say, integration by parts—is explained differently by 3Blue1Brown, Professor Leonard, and Khan Academy. Pulling transcripts from all three and reading them side-by-side reveals which framing clicks best for your learning style.
How to Use
Find your math video on YouTube
Search YouTube for the calculus lecture, algebra tutorial, or math competition walkthrough you want to study. Copy the full URL from your browser's address bar.
Change youtube to 2outube
In the URL, replace 'youtube.com' with '2outube.com'—for example, youtube.com/watch?v=WUvTyaaNkzM becomes 2outube.com/watch?v=WUvTyaaNkzM. Press Enter.
Copy the transcript into your math notes
The full transcript loads instantly. Select all, paste into your note-taking app, then annotate with proper math symbols, highlight key theorems, and add your own worked examples alongside the instructor's explanations.
Questions
Does this work with any YouTube video?
Yes, any video with captions.
Is it really free?
Completely free. No account, no limits.
Do math video transcripts include equations and formulas?
Transcripts capture the spoken audio, so you'll get the verbal description of equations—for example, 'x squared plus two x minus three equals zero'—rather than rendered LaTeX.
Can I transcribe long university math lectures?
Yes. There's no length limit. Channels like Professor Leonard post 2–3 hour calculus lectures, and 2outube handles them just like any other video. The full transcript loads in seconds regardless of video length.
Which math subjects have the best YouTube transcript coverage?
Calculus, linear algebra, statistics, and pre-calculus have excellent coverage because channels like Khan Academy and Professor Leonard auto-generate accurate captions. More niche topics like category theory or number theory may have sparser or less accurate auto-captions depending on the creator.
Can I use math video transcripts for studying exam problems?
Absolutely. Worked example transcripts are especially useful—search the transcript for 'example' or 'problem' to jump straight to practice problems, then use the step-by-step verbal explanation alongside your own notation to build a problem-solving reference sheet.
Does 2outube work on mobile for math lectures?
Yes. Just edit the URL in your mobile browser the same way—replace 'youtube.com' with '2outube.com.' The transcript page is mobile-friendly, so you can read and copy the transcript directly on your phone or tablet.
Can I translate a math transcript into another language?
Yes. Once you have the transcript text, paste it into any translation tool (Google Translate, DeepL, etc.).
