Description
Built this because I was tired of every AI tool shipping my data to someone else server n0x runs the full stack LLM inference via WebGPU, autonomous ReAct agents, RAG over your own docs, sandboxed Python execution via Pyodide all inside a single browser tab. No account No keys No backend Models download once, cache in IndexedDB permanently. Biggest challenge was context window budgeting for the agent loop and making the WASM vector search non-blocking. Happy to talk architecture.GitHub: https://github.com/ixchio/n0x | Live demo: https://n0x-three.vercel.app

Could you build this?
Yes The application combines pre-existing open-source web technologies (WebLLM for WebGPU inference, Pyodide for Python execution, and client-side vector/search libraries) in a static React frontend.

Same idea, different domain
Nobody's really built a model & infra tool for Fintech yet.
