Launch HN: Keet (YC S24) – An app to create video courses on anything

At first glance, Keet seems like just another edtech tool—an app that creates video courses on any subject. But look closer, and you'll see the ghost of something profoundly weird. The app is essentially a *generative curriculum engine*, a machine that doesn't just organize existing content but actively constructs a course from the aether of the internet. Zack and Tommy, who met in a linear algebra class, have built a tool that turns the ancient, human-crafted arc of education into a fluid, algorithmic flow. This is the commodification of the syllabus, and it's a little like watching a black hole form: all the familiar structures of learning get compressed into a singularity of pure information. The deeper, more fascinating implication here is about the nature of knowledge itself. For centuries, we've assumed that a curriculum is a kind of map—designed by experts, sequenced for cognitive absorption, and validated by institutions. Keet's approach suggests that a curriculum is just a pattern, a set of logical dependencies that an AI can infer and then narrate. When learning becomes an on-demand, generative process, we have to ask: what is the *authority* of knowledge? If the AI can generate a course on quantum mechanics or the history of the Ottoman Empire in seconds, does the human expert become obsolete? Or does the AI simply become a new kind of librarian, one that can read a library in a second and then tell you a story about it? The "games for reinforcement" aspect is the most sneaky subversive part. It turns the learning process into a kind of cognitive training loop, much like how our brains form habits. This is where Keet aligns with the weirdest findings in neuroscience: learning isn't the transfer of facts, but the strengthening of neural pathways through repetition and reward. By gamifying the course, Keet is essentially performing a little digital neuroplasticity on you. The curriculum isn't just presented; it's *drilled* into your brain through game mechanics. The result is a hybrid of a Socratic dialogue and a slot machine. Of course, this is all speculative. Keet is a mobile app, a YC S24 company, and we haven't seen the quality of the generated courses yet. But the *principle* is what matters. We are in the midst of a revolution where the medium of instruction is becoming the same as the medium of generation. The future of learning might not be a classroom, but a mirror—an AI that reflects not what you know, but what you *could* know. And that's a little bit terrifying and a little bit wonderful.
