AI That Builds Screens, Not Just Text
An open-source AI powerhouse that runs locally in your pocket. With persistent memory, a heartbeat, tool execution, and an interactive UI that generates full screens — not just chat bubbles.
A personal AI assistant that remembers, acts, and adapts — across every platform.
Kai remembers facts, preferences, and learnings across conversations. Frequently used memories get promoted into the system prompt automatically.
Define Kai's personality with an editable system prompt. Choose from presets like Short & Direct, Tutor, or Creative Writer — or write your own.
Kai runs periodic self-checks in the background — reviewing memories, pending tasks, and emails. If something needs attention, it notifies you.
OpenAI, Gemini, Anthropic, DeepSeek, Groq, Mistral, xAI, and more. Configure a fallback chain — Kai tries the next provider on failure.
Web search, notifications, calendar events, shell commands, and alarms. Kai acts on your behalf, not just talks.
Connect to external tools via the Model Context Protocol. Fetch web content, query docs, check crypto prices, and more.
On Android, Kai runs shell commands in a secure sandboxed Alpine Linux environment. Install packages, run Python, process data.
Everything runs on your device. Conversations are encrypted locally. No cloud accounts, no tracking, no data collection.
Android, iOS, Windows, Mac, Linux, and Web. Pick your platform.
