Transcribe Online Course Videos on iPhone
Udemy, Coursera, and similar platforms show captions in the player — and the player is where the text stays. There's no export path for the transcript on iOS, no summary, and no translation of the lecture for non-native speakers. Studying an online course means replaying video, which is the slowest possible way to take notes.
Ground rules first, stated honestly: course videos belong to the platform, and you may only keep them per its terms. Coursera and Udemy offer in-app offline viewing, not file export, so the file path exists only where the platform permits it — your own recordings of live sessions, offline files you're entitled to keep, or screen recordings of material you're entitled to view. This page never recommends bypassing access controls.
Within those rules, the workflow is the one we use for transcribing video to text on iPhone: get the lecture into Files, import it into Audio Notes AI, and study from a searchable transcript with summaries and translated notes.
How to Transcribe Online Course Videos on iPhone
Three steps: get the lecture into Files, import it, study the text. The app sits in the middle and does the transcription.
1. Get the lecture into Files, within the platform's rules
Use in-app offline viewing where the course app allows it and you're entitled to keep the content; screen-record material you're entitled to view; or record your own live session. A lecture exported from a platform you're allowed to download from, or recorded during a live session you attended, both qualify — the entitlement question is yours to answer, and the app doesn't second-guess the file. Export your own clips from Photos to Files — our lecture recording guide covers keeping the audio clean. What you must not do is bypass DRM or violate the platform's terms; the honest version of this workflow stays inside your entitlements, and it's plenty.
2. Import the file and Whisper transcribes it
Choose the video in the Files picker inside Audio Notes AI, or use the iOS share sheet. The app extracts the audio track on-device to M4A and uploads it; openai/whisper-large-v3-turbo transcribes it server-side, with large-v3 as fallback, auto-detecting the language from 99 Whisper languages plus Cantonese. For foreign-language courses, set the language explicitly rather than trusting auto-detect — it makes the biggest accuracy difference for the least effort. Course audio is studio-recorded in most cases — one speaker, no background noise — which is Whisper's best condition, so accuracy on course videos is typically at its strongest. Internet required, iOS only, 90 minutes per recording; modules usually fit in one import.
3. Study from searchable text
The transcript is searchable and copyable — search the concept, not the timeline. When the lecture language differs from your preferred language, the app automatically translates and summarizes it into your preferred language, which is the key feature for non-native learners: read the summary in your language, check the original transcript underneath. The transcript and summary stay attached to the same note, so a module's key points are reviewable in one screen the night before an exam. Copy sections into your notes app, export a PDF, or share through an encrypted link (AES-256-GCM, key in the URL hash, 24-hour expiry). These are the same file-first mechanics as the rest of the video-to-text guides, applied to recorded lectures, YouTube-hosted material, and webinar sessions.

FAQ
Can I download Udemy or Coursera videos?
Only what the platform permits. Both offer offline viewing inside their own apps — that's not a file you can import — and neither documents a transcript export path on iOS. The practical routes are screen-recording material you're entitled to view or using files you legitimately have. If a platform offers a download option within its own terms, use it; the file import accepts whatever legitimate format that produces. We don't recommend, and won't describe, ways around platform terms.
What if the course is subscription-gated?
Transcribe what you're entitled to view, and stop there. Subscription-gated content stays in the player; the honest workflow applies to your own recordings and material you may keep. The app is a file importer, not a course ripper — it never connects to any course platform, which is also what keeps the process clean and simple.
Does it translate lectures into my language?
Yes, automatically. When the lecture's language differs from your preferred language, the transcript is translated and summarized into your preferred language — the pipeline documented in our any-language guide. That's the feature non-native learners rely on: read the English summary, check the original-language transcript underneath.
Can I summarize a whole module?
Module by module, yes: each lecture imports and transcribes on its own, and the summary lands per recording. With a 90-minute cap per file, a module made of hour-long lessons is one import each. The full 10,000-minute monthly allowance on Pro covers heavy course loads without counting — and the free tier's 60 lifetime minutes still fit a few lectures to try it.
How long can a lecture be?
90 minutes per recording, and about 50 MB per upload. Longer sessions split at a natural break — the app's extraction handles mp4, mov, m4v, avi, and mkv, so the format rarely matters. The free tier gives you 60 minutes of lifetime transcription, a one-time allowance, not a monthly one. Audio-only course audio, like language drills, imports through the voice-message workflow.
Audio Notes AI imports video files — mp4, mov, m4v, avi, and mkv — extracts the audio, and transcribes it server-side with Whisper (large-v3-turbo, large-v3 fallback) in 60+ languages. Every account includes 60 minutes of lifetime transcription for free; Pro ($5.99/month) unlocks 10,000 minutes per month with a 90-minute cap per recording. Transcripts are translated and summarized automatically into your preferred language, and shared notes are encrypted with AES-256 on your iPhone before upload.
