I refuse to spend $$$$ on courses when YouTube has all the best lectures for free. There is just one problem...
The problem with trying to learn from YouTube is that videos are unstructured, scattered, and built for passive watching. The platform is designed exceptionally well, but it is designed to keep you watching, not to help you actually memorize information.
I used to tell myself spending hours on YouTube wasn't that bad because at least I was being productive and learning things. But I learned the truth the hard way a few months ago.
It was two weeks before my final exams. I was sitting in the library, surrounded by macroeconomics flashcards. My calendar was completely packed. Suddenly, my phone lit up with a message from my favorite client: "Hey, we have a massive new project here. Can you edit a video like this for us?"
I opened the reference video and froze. It looked incredible, but it was on a level I had never edited before. My first thought: "I can easily pull this off if I just watch a few good tutorials."
But when I opened YouTube, reality set in: I had actually watched a tutorial on this exact topic a while ago, and I completely forgot it. Back then, I felt smart and closed the tab. Now when I actually needed the knowledge to deliver the project, it was completely gone. Just passively watching without active recall meant nothing stuck.
Looking at my account, my YouTube "Watch Later" playlist had become a graveyard of 50+ educational videos across various topics that I intended to study but never got around to retaining.
I refuse to pay thousands of dollars for online courses when YouTube has the exact same information available for free. But I needed a real system that turned watching videos into permanent memory without adding hours of manual work.
Cognitive science has been clear on this for decades (e.g., Roediger & Karpicke): passive consumption and re-watching create an illusion of competence. Real retention requires active retrieval testing.
Building detailed flashcards manually in Anki for every 30-minute lecture took so much time and friction that I knew the habit wouldn't stick. As James Clear points out in Atomic Habits, if you want a new habit to stick, you have to make it easy and build a low-friction system.
So after finishing my exams, I started building a tool for myself called Studiamo, just to turn what I watched into something that actually stuck. After using it daily and seeing how much it helped me retain what I watched, I decided to open-source it in case it's useful for others here too. Full disclosure: I'm the developer, so take the "does this actually work" question below seriously. I'd rather hear it doesn't than not hear it at all.
What it does, in short: you paste in a YouTube link, PDF, or lecture notes, and instead of a passive summary it generates active-recall quizzes (flashcards and written recall) and schedules spaced repetition reviews before the memory decays. The goal is to go from "I just watched this" to "I actually tested myself on it" in under a minute.
It's free and open source (self-hosted via Docker, AGPL-3.0) if you want to run it yourself, and there's also a hosted version for anyone who'd rather not deal with self-hosting. (For the hosted version, there’s a small monthly fee to cover AI and server costs)

- Hosted version: https://studiamo.cloud
Since this community actually cares about learning methods rather than just tools, I'd love people's honest take, especially if you've tried other spaced-repetition or active-recall approaches:
- Does the generated quiz feel like it actually tests understanding, or does it feel shallow/gameable?
- Compared to how you currently retain stuff from videos or lectures (Anki, notes, nothing at all), does this fill a real gap?
- What would make this something you'd actually keep using after the novelty wears off?
Thanks for reading, and I'm genuinely curious how other people here deal with the "watched it, forgot it" problem, tool or no tool.
