Transcribe Physics Lectures from YouTube
Get physics lecture transcripts by swapping one letter in the URL
Or just change youtube.com to 2outube.com in your browser
To transcribe any physics lecture from YouTube, just change 'youtube.com' to '2outube.com' in the video URL. You instantly get the full transcript — ideal for copying equations, key definitions, and derivations from lectures by MIT, Khan Academy, or any physics channel.
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 Physics Lectures from YouTube Channels to Transcribe
MIT OpenCourseWare
Full university physics courses from MIT, including classical mechanics, electromagnetism, quantum mechanics, and thermodynamics taught by MIT professors.
Khan Academy
Beginner-to-advanced physics lessons covering forces, energy, waves, optics, electric fields, and AP Physics prep.
Physics Explained
In-depth conceptual and mathematical physics videos covering topics like special relativity, quantum mechanics, and electrodynamics with rigorous derivations.
DrPhysicsA
University-level physics lectures on mechanics, thermodynamics, electromagnetism, and quantum physics aimed at A-level and undergraduate students.
Best Practices for Physics Lectures from YouTube Transcripts
Flag equations by keyword
Physics transcripts won't render LaTeX, but spoken cues like 'equals,' 'squared,' and 'over' appear verbatim.
Use timestamps to anchor your notes
Each transcript line includes a timestamp. When you pull a key derivation or definition into your notes, note the timestamp.
Copy definitions verbatim for flashcards
Physics definitions are precise — paraphrasing them risks introducing errors.
Paste into an AI model for problem breakdowns
Paste the full lecture transcript into ChatGPT or Claude and ask it to extract all worked examples, list assumptions made.
How to Use
Find your physics lecture on YouTube
Search YouTube for the lecture you need — an MIT OCW mechanics course, a Khan Academy electromagnetism video, or any.
Change youtube to 2outube
In the URL, replace 'youtube.com' with '2outube.com'. For example: youtube.com/watch?v=wWnfJ0-xXRE becomes 2outube.com/watch?v=wWnfJ0-xXRE. Hit enter.
Read, copy, or study the transcript
The full transcript loads instantly. Scroll through to find equations, definitions, or derivations.
Questions
Does this work with any YouTube video?
Yes, any video with captions.
Is it really free?
Completely free. No account, no limits.
Do MIT OpenCourseWare and Khan Academy physics lectures have captions?
Yes. Both MIT OCW and Khan Academy consistently provide captions on their YouTube videos, making them fully compatible with 2outube. Most major educational physics channels do as well.
Will the transcript include the math and equations from the lecture?
The transcript captures everything spoken aloud. Professors typically narrate equations as they write them — 'F equals m times a' or 'psi squared' — so the spoken math appears in.
Can I use the transcript to study for AP Physics or university exams?
Absolutely. Many students paste lecture transcripts into note apps or AI tools to generate summaries, extract key formulas, and create practice questions. It's especially useful for reviewing dense derivation-heavy lectures before exams.
What if the physics lecture doesn't have captions?
If the video has no captions — auto-generated or manual — 2outube won't be able to produce a transcript.
Can I get transcripts for an entire physics course playlist?
Yes, one video at a time. Open each lecture in the playlist, swap 'youtube' for '2outube' in the URL, and grab the transcript.
How is this different from YouTube's own transcript feature?
YouTube's built-in transcript is buried in a menu and formatted as a scrolling panel inside the video player.
