Show HN: Lathe – Use LLMs to learn a new domain, not skip past it

In a sea of "let the robot do it," Lathe rolled into Show HN with the exact opposite pitch: use artificial intelligence to teach you step by step, not to do the thinking for you. The app creates hands-on tutorials on almost any topic, then makes you work through them in a local reading interface like it’s 2007 again — yes, complete with a little "back in the stone age" swagger from the creator. And honestly? The comments were surprisingly wholesome... with just enough side-eye to keep things spicy.

The biggest vibe in the thread was relief. One commenter called it a "sane way to use" AI in "this crazy time," which basically sums up the mood: people are exhausted by tools that promise shortcuts and are oddly excited by one that says, "Nope, you still have to learn." Others jumped in with quick-hit approval — "Love this idea" and "great, I’ll try this" — giving the launch strong "finally, an AI that doesn’t instantly replace my brain" energy.

But this wasn’t pure group hug territory. One commenter coolly shrugged and said they already use Google’s guided learning tools, a classic internet move: nice project, but my giant tech company already has that. Another pushed harder, questioning whether the creator really uses the tool enough and poking at the claim that having another AI verify a tutorial is even much of a feature. Translation: cute idea, but does it actually hold up in real life? That little burst of skepticism gave the thread its drama — not a flame war, but a very Hacker News version of one: polite doubt, faint suspicion, and a demand for receipts.
