Saw recommended in PC Mag and just used for YouTube download to experiment with AI transcription and summary tools – worked like a charm.
From PC Mag article:
Its no-frills interface belies a lot of power (you can change many settings and should do so before you first download). It’ll download just audio if you want MP3s. For video, it supports 8K on down. It will even do something called “remuxing,” (yes, with a “u”) in which it changes a video file that may be damaged by putting it into a new file container, potentially repairing it. Cobalt is operated by one developer who has made the site free of trackers, analytics, and ads. It’s open source, so others can take the code and host it themselves. And it’s all free—though donations are appreciated. Here’s hoping it will stand the test of time.
