🧰 25 AI projects

Each app pairs a real local engine (SQLite in WebAssembly, a d20 game engine, a Web Audio synth, a crossword constructor, OKLCH color math, Elo ratings…) with LLM features. Everything runs in your browser: open one and try it in demo mode, or paste a free Groq key for live AI. One key works across all of them.
