Description

Russet enables private on-device AI on iPhone and iPad, powered by the latest and greatest models. By default, chats run fully on-device with no accounts, no ads, and no tracking of messages. Russet's models are optimized for Apple hardware and downloadable, so they work completely offline. All in one clean, native interface designed for privacy, focus, and flow.

Features
• Flexible chats: Choose models, adjust response style, branch or lock chats, and analyze PDFs and images.
• Text-to-speech: Import speeches generated in custom voices from Russet for Mac.
• Agent: Work with health data, schedules, contacts, and files through system-aware automation.
• Flow: Summarize, rewrite, debate, label, and translate text, even offline.
• Intelligent Templates: Get instant briefings powered by your calendar.
• Interactive stories: Create and explore text-based adventures in Agent > Game.
• Offline-ready: Works without an internet connection.
• Multilingual: Supports 13 written and spoken languages.

- Export chats to open as view-only on other devices running Russet.

- New models: PrismML's Ternary Bonsai and Google's Gemma 4.
