Wondering▲345Hey HN! I’m excited to show you my app that lets you learn any topic in a structured, bite-sized way. Each lesson has an audio version, some visuals, and interactive quizzes. They’re personalized to your background and goals, and you can pick a concept inside a lesson and ask it to go deeper. When my co-founder was at NotebookLM, he realized the biggest bottlenecks in learning are that people don’t have time or feel like they’re not smart enough. We wanted to see if software can take the mental load of figuring out what resources to use and what order to learn them in, and make lessons easy…

Given the fact that we are limited to seeing only one output at a time, it's kind of hard to compare outputs from different models, adjustments made to the prompting, and sampler settings. But even when keeping the generation parameters the same (e.g., to test for reliability in the output) and just going for multiple passes, there is no easy way to have a side-by-side comparison to keep track of the outputs from the multiple "rounds".

I made this experimental art project/game that's an LLM chat assistant, but where you're the AI. I wanted people to get a visceral sense of what it's like to answer the kinds of things that people prompt their chatbots day in and day out. If you're interested, I wrote up some more info on how I made it, including how the "user" prompts are generated with an eye for realism: https://bethechatbot.com/about Hope you enjoy it! I'd love to hear people's takeaways.

Hey HN! I've built Curiosity of the Day to help people increase their knowledge of the world, one day at a time. Each day, it presents the user with a new fact or piece of knowledge about anything from history and science to art and culture. I’d love to get some feedback on ways to make the app better, and any other ideas on how to make learning more fun and engaging.
