🎯 100 Local LLM Projects

A curated collection of 100 production-level AI applications — all running locally with Gemma 4 + Ollama. Zero cloud costs. 100% private.

🎬 Demo

Each project includes a Streamlit or FastAPI web interface. Launch any project and interact with it through a clean, modern UI — all powered by a local LLM with zero API calls.

🔥 Why This Exists

Cloud AI APIs are expensive, rate-limited, and your data leaves your machine. This collection proves you can build production-quality AI applications that run entirely on your hardware. From healthcare to legal, education to creative writing — 100 real-world tools, all powered by a single local model.

Whether you're a developer exploring LLM capabilities, a privacy-conscious professional, or someone who wants to build AI tools without recurring API costs — this repo is your launchpad.
