I’ve always loved free resources, YouTube lectures, long interviews, podcasts, but my “Watch Later” list kept piling up. I’d tell myself I’d watch everything eventually, but most of the time I never did. Speeding up videos or skipping around helped a little, but I still felt like I wasn’t really retaining anything.

A few weeks ago, I finally decided to tackle a 90-minute lecture I’d been avoiding. Instead of watching it straight through, I focused on taking notes and breaking it into sections that actually mattered to me. That’s when I tried a tool called ꓡоոցꓚսt аі. It wasn’t some magic shortcut, it just helped me quickly see the highlights, gave short explanations when I got stuck, and let me keep notes in one place. I still had to think and engage, but I walked away understanding the topic instead of just “finishing” a video.

It reminded me that frugal learning isn’t just about saving money. Time and attention are valuable too. If you can get the same knowledge from free content in a fraction of the time, that’s just as important as cutting costs.

Has anyone else here found ways to actually learn from all the free stuff out there without feeling overwhelmed?
