We built Arbiter because we 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.

Hi everyone! I’m Jordan, the developer behind Arbiter.
This project started as a weekend experiment to see how well on-device models could perform on my iPhone 14. From that small experiment, I quickly began to realize how big this space could become.
My goal with Arbiter is to show that AI doesn’t have to live in the cloud to be powerful. It can run locally, respect your privacy, and still feel fast and intuitive.
I’d love to hear how it performs for you and what features you’d like to see next. Appreciate your support and feedback!
