Arbiter

I built Arbiter because I believe that powerful and useful AI doesn’t need to live in the cloud, where it's controlled and monitored by billion-dollar tech companies. Arbiter is a privacy-first offline AI assistant that runs entirely on your iPhone. There are no accounts, no servers, and no data collection. Choose from a range of open-source models like Gemma and DeepSeek, chat instantly, and keep every conversation safe on your device.
