Videos, lectures and podcasts
Turn what you watch and listen to into materials, with captions or on-device transcription.
Much of what people learn now is watched rather than read. So when a window you approved starts playing, CogniPage captures what is said instead of the page around it — and the lecture becomes a material like any other, with the same flashcards, the same recall schedule and the same place on your knowledge map.
How it works
-
Play something in a window CogniPage can see
A lecture, a course video, a podcast episode — in a browser or a local player.
-
Approve that specific piece of media
You are asked per video, not per site. Approving a lecture says nothing about the next video on the same platform: that gets its own question.
-
The words become a material
Captions are read where the service publishes them — instantly, and at no cost. Where none exist, CogniPage can listen and write the transcript itself, on your computer.
-
Adverts are left out
Ad breaks are detected and skipped, so a sponsor read never turns into a flashcard.
What is recognised
| Course platforms | Coursera, Udemy, edX and any university running Open edX, Udacity, FutureLearn, Khan Academy, Alison, NPTEL |
| Professional | LinkedIn Learning, Pluralsight, Skillshare, O'Reilly, MasterClass, Teachable, Thinkific |

The pages you read around a course — the syllabus, the notes, the quizzes — keep being captured as reading, exactly as before.
On-device transcription
Transcribe when there are no captions is off until you switch it on. Turn it on and CogniPage listens to the audio the approved application is playing and writes the transcript itself. Everything happens on your computer:
- No audio and no transcript ever leaves the machine.
- It costs no AI credits.
- No audio file is written to disk — only the resulting text is kept.
- Nothing is downloaded, ripped or saved from the service you are watching.
Choosing a speech model
Switching transcription on reveals the model list: Fastest (32 MB), Balanced (57 MB, the default) and Most accurate (181 MB). A bigger model is more accurate and slower. Each shows whether it is downloaded, and you download or delete them here — nothing is fetched until you ask for it, and you can delete a model again at any time to reclaim the space.
CogniPage requests no microphone permission at all. It taps the audio that one specific application you approved is already playing — a call, a notification or anything else on your machine is not part of it.
Turning it off
Switch off Capture what you watch and listen to and CogniPage goes back to reading only what is written on screen. Transcription can be left off independently, in which case captions are still used wherever they are published.
