Udemy Transcript Extractor

About

Download complete transcripts from any Udemy course you're enrolled in organized, searchable, and ready for note-taking, study or AI summarization.

━━━ HOW IT WORKS ━━━

1. Open a Udemy course you're enrolled in
2. Click the extension icon
3. Click "Extract transcripts"
4. Download a ZIP with one .txt file per lecture, plus a combined full-course transcript

A 200-lecture course takes about 2 minutes.

━━━ WHAT YOU GET ━━━

- One .txt file per lecture, named and numbered to match the course curriculum
- Chapter folders that mirror the course structure
- A single _full-transcript.txt for full-text search across the entire course
- Clean plain text — timestamps and duplicate caption cues removed
- English captions by default, with automatic fallback to available locales

━━━ PRIVACY ━━━

Everything runs locally in your browser. There are no external servers, no 
analytics, no tracking, and no third-party requests. The extension only talks 
to udemy.com using your existing logged-in session — exactly like your browser 
already does when you watch a lecture.

Transcript data is wiped from local storage the moment your download completes.

━━━ BUILT FOR SAFETY ━━━

- Manifest V3, strict Content Security Policy
- No eval, no remote code, no innerHTML
- Every network request validated against a *.udemy.com allowlist
- Rate-limited (500ms between requests) to be respectful of Udemy's servers
- Open source — audit the code at github.com/iamafram/udemy-transcript-extractor
