Show HN: I built a Free "Masterclass" from YouTube clips

https://opencademy.com/
6•longerpath•3mo ago
The idea: what if you could get a “Masterclass”-style experience, but free, using existing YouTube content?

So I made OpenCademy — right now it only has two quick startup "courses" (101 & 102), built from curated YouTube clips, all embedded and organized into modules.

It’s still early (no accounts, no backend), but it’s bingeable.

Would love thoughts on whether this concept feels useful or just... redundant.

HardwareLust•3mo ago
Who curated the clips, and what was the criteria used for choosing them?
longerpath•3mo ago
I curated the clips (but didn't create them).

Criteria was: is the person a successful startup founder? And does the clip contain practical advice?

HardwareLust•3mo ago
That's kinda what I had assumed, just wanted to make sure you weren't using AI or something like number of views
longerpath•3mo ago
AI might have been a disaster here, I think.

I agonized for a long time about which clips should go in vs. which should be left out.

But it's subjective. For example, if I want to add a basic cooking course - who should I choose to be the authority on cutting vegetables? Ideally, I'd want a professional in that domain to do the curation.

Tactical45•3mo ago
Just saw a few of the clips from 101 and think you've curated pretty good content here. Even beyond initial learning, I like to revisit good content / lessons every now and then.

Any plans to add other subjects?

longerpath•3mo ago
Hey thanks for checking it out!

I will add more subjects in the future, hopefully based on feedback - would you like to see more Business courses or more fun/creative ones (e.g. Home Cooking 101)?

Tactical45•3mo ago
I could see creative being fun, but if I had to upvote another area it would be health (nutrition, sleep, diet, etcl
