Or just change youtube.com to 2outube.com in your browser
To transcribe a YouTube lecture, just change 'youtube.com' to '2outube.com' in the video URL and press Enter. The full transcript appears immediately — no signup, no copy-paste. Transcripts let you search for exact concepts, study key terms, and build notes without rewatching the entire lecture.
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
Why Transcribe Lectures from YouTube
Video lectures don't have Ctrl+F.
Copying key explanations directly from a transcript is far faster than rewinding and retyping.
Libraries, offices, and shared spaces make watching lectures impractical.
Technical lectures in subjects like mathematics, economics, or science often move faster than you can absorb aurally.

Tips for Transcribing Lectures from YouTube
Use the transcript to create a lecture outline
Paste the full transcript into a document and break it into sections by topic.
Check auto-captions against the speaker
YouTube's auto-generated captions are accurate for most lectures, but technical jargon, foreign names, and mathematical notation sometimes get mangled.
Timestamps let you jump back to specific moments
The transcript is timestamped.
Combine transcripts from multi-part lecture series
Many courses publish lectures in parts.
Sample Workflow
Find the MIT lecture
Find the MIT lecture on YouTube (e.g., 18.01 Single Variable Calculus), copy the URL, and swap 'youtube.com' to '2outube.com'
Scan the transcript for key
Scan the transcript for key definitions and worked problem steps, copying them directly into a structured Notion page organized by topic
Use the timestamped transcript
Use the timestamped transcript to revisit only the sections you didn't fully grasp, saving 40+ minutes versus rewatching the full hour
Questions
Does this work with any YouTube video?
Yes, it works with any video that has captions. Most YouTube videos have auto-generated captions.
Is it really free?
Completely free. No account, no subscription, no limits.
Do university and academic YouTube channels have captions on their lectures?
Most do. Major academic channels like MIT OpenCourseWare, Yale Open Courses, Stanford Online, and Khan Academy consistently have captions — either auto-generated or manually added. Independent professors vary, but the majority of full-length lecture videos on YouTube include auto-generated captions.
How accurate is the transcript for technical lecture content?
YouTube's auto-captions are highly accurate for standard spoken English. Technical terms, field-specific jargon, and equations are the most likely sources of error. Always cross-reference unfamiliar technical terms against the video before using them in assignments or exams.
Can I transcribe a lecture that is several hours long?
Yes. 2outube loads the full transcript regardless of lecture length. Long lectures — including multi-hour seminars or recorded class sessions — are handled the same as short clips.
Can I get the transcript in a language other than English?
2outube displays whatever captions the YouTube video has available. If a lecture has manually added captions in another language or auto-generated captions in the video's spoken language, those will appear.
Does the transcript include the professor's exact words, or is it a summary?
The transcript is a verbatim record of what was said in the video — not a summary, paraphrase, or AI-generated interpretation. You get every word spoken, with timestamps, exactly as the lecture was delivered.
Can I use 2outube transcripts for citation or academic reference?
Transcripts from 2outube reflect the spoken content of the video, which is citable as a YouTube lecture in standard academic formats (APA, MLA, Chicago). Always cite the original video rather than the transcript tool.
