Neuro — Local Fine-Tune

Fine-tune AI models directly on your iPhone — fully offline, private, and free. Train real models on real data. Open source, no account needed.

Neuro lets you fine-tune real AI language models directly on your iPhone — no cloud, no servers, no data leaving your device. Pick a base model from the built-in catalog, choose a dataset (or bring your own), and train a specialized version tuned to your task. Everything runs locally using Apple's Neural Engine and GPU, powered by RWKV — an efficient architecture built for on-device use. FEATURES

• Browse and download open models and datasets • Five training intensity levels, from light head-tuning to deep fine-tuning • Real-time training progress: loss, accuracy, memory usage • Fully offline — your data never leaves your device • Free and open source

Neuro is built for people who want to experiment with real machine learning on real hardware, without renting a GPU or sending data anywhere. Whether you're a student, a researcher, or just curious how fine-tuning works, Neuro gives you a hands-on, private way to do it. This is an early release — expect rough edges, and expect it to get better. Feedback and contributions are welcome on GitHub.
