Hi HN! We built this to make "why AI works" feel tangible without drowning in math; feedback welcome!

- What it is

We built a structured AI-literacy platform to unpack core AI concepts with: bite-sized lessons + post-lesson quizzes, dozens of in-browser visualizers (neural nets, tokenizers, CNN, GPT-2, etc.), audio and curated videos, and daily AI news feed.

- Why we built it

Most AI courses right now felt either too math-heavy, too surface-leveled, too narrow (covers only a tiny side of AI), or just too expensive. We wanted a single place that balances rigor with intuition - accessible enough for high schoolers (and possibly younger), and structured enough to give adults a solid foundation.

- Who it's for

Anyone curious about AI (what it is, how it works, why it works, and when it doesn't), and in particular high school and college students who should really learn AI fundamentals like they do math and English, teachers looking for classroom-ready materials, adults who find themselves lost in jargons and just want to make sense of it all.

- What to try

Lessons + Thinking Corner & Teacher Notes + audio clip - start with Unit 1's first 5 lessons (after sign up, free); go through the slides, check out the Thinking Corner/Teacher Notes on each slide for additional insights, and pop up the accompanying audio clip to reinforce the slide material.

AI visualizers - GPT-2 Explorer, Tokenizer Playground, Neural Network Visualizer (free). Each visualizer includes sources and a brief 'how it works' section.

Assessments - take the short check-for-understanding at the end of each lesson.

Curated videos (YouTube) - browse through a library of handpicked short videos to reinforce concepts.

AI news feed - finish the day with a 2-minute skim of today's AI headlines; it uses AI to retrieve and rank the news with source-links.

- How we built it

React front-end + Python/Flask services (parts scaffolded with Lovable). Slides via Gamma. Visualizers are a mix of in-house and open-source (credited). Audio clips are generated using NotebookLM with context.

- Limitations

Balancing layman-friendly explanations with technical accuracy was not easy - corrections are welcome.

- Roadmap / feedback

Did we get anything wrong? Where does the difficulty curve feel off? What new content or features should we add? Our current plan is to add more lessons and visualizers. We are also exploring whether to add more practical lessons like building agents, vibe-coding app development, etc. Ideas and critiques are very welcome. Thanks!

Really impressive work! I wonder how easy would it be to support (a future open source version of) SORA using Groq's design. Will there be a Video Processing Unit (VPU)?

We have created a 3D asset marketplace that contains a set of (expanding) categories of AI generated 3D base meshes that are mobile compatible with free AI-texturing. You can change polycount and also turn mesh into voxels, pretty cool for putting together assets for Roblox and Minecraft type of games. Go check it out and we welcome any feedback!

AFAIK, model behind yiyan is Baidu's ERNIE. Yi-34B (and Yi model family) comes from another startup created by Kai-fu Lee earlier this year: 01.ai.
