FAQ
How do I take notes on a YouTube video with Cosminds?
Paste the link. Cosminds fetches the video's captions, extracts the specific claims, and organizes them by idea alongside everything else you have learned. You never watch the video twice to find the one point you wanted.
Does it work for any video?
It works for any YouTube video that has captions, which is most of them, and for podcasts that publish a transcript. It reads the captions rather than transcribing audio, so there is nothing to upload and no wait.
