Really useful on a daily basis!
I've fallen into a habit of watching YouTube videos for information, and TubeOnAI is exactly the tool I've been looking for: Instead of having to watch a whole 15- to 30-minute video to see if there's anything worthwhile in it, I can get a good summary *really* quickly. Then I can decide whether or not to watch the video, to delete it from my feeds, or to save a Markdown-friendly version of the summary to keep in my "second brain".
(Devs: I'd like it if the summary contained a link to the original video, just for later reference.)
I haven't tested the content-creation functions yet, but I cranked this up to Tier 3 just because I really enjoy using the tool and prefer not having to think about credits or limits. I've been generating summaries like mad for a week now, and I've barely made a dent in my credit allowance.
I've run into a tiny glitch here or there, but I'm really not bothered by them; they're drastically outweighed by how amazing this tool is at taming YouTube.
