Russet

Support Page

Russet is your private, customizable, and portable AI companion powered by Apple Intelligence. All chats run fully on-device by default. In addition to Apple Intelligence, Russet provides access to several other offline-capable AI models you can download that are optimized to run on Apple devices. And if you want, you can also bring over your OpenAI API key to access their cloud models like GPT-5.1 and GPT-5 mini—all within Russet. Chat; read, and write faster with Flow; manage your Calendar, Contacts, and Health data using powerful, offline Agentic tools; and dive into text-based adventures in Game—all without ever needing an internet connection. Just like the resilient russet potato, Russet thrives anywhere, anytime. No accounts. No ads. Completely free.

Start conversations with intelligent Templates that leverage deep system integration: get instant briefings populated with your actual calendar events for today, tomorrow, or the entire week ahead—all processed privately on-device. Russet combines conversational intelligence with your real system data to help you plan, prepare, and stay organized. Got a PDF? Drop it in chat! Russet can read it, pull out the important stuff, and answer your questions. Your file stays on your device and is never uploaded to the cloud, ensuring full privacy.

Customize how Russet thinks: adjust creativity, tune its style, and provide additional guidance to get what you need. Got a chat for your eyes only? Lock it instantly with on-device biometrics. Want to explore a different conversation path without starting from scratch? Simply branch the chat. Got some text that needs to be revised, labeled, debated, summarized, or rewritten? Use the powerful yet simple Flow mode.

Your calendar events, your contacts, your health, your files—whatever Russet sees stays yours and only yours: offline, off-grid, anywhere.

A clean, lightweight, and native interface designed for privacy, focus, and flow. Intelligence that works for you whenever, wherever you want.
