Kai 9000's Interactive UI lets the AI generate full interactive screens — quizzes, dashboards, recipes, brainstorms, and more. Navigate by tapping buttons instead of scrolling through chat.
Features
Persistent memory — Kai remembers important details across conversations and uses them automatically
Customizable soul — Define the AI's personality and behavior with an editable system prompt
Multi-service fallback — 24 LLM providers with automatic failover
On-device inference — Run AI models locally on Android using LiteRT, no internet needed
Tool execution — Web search, notifications, calendar events, shell commands, and more
MCP server support — Connect to remote tool servers via the Model Context Protocol
Autonomous heartbeat — Periodic self-checks that surface anything needing attention
Settings export/import — Backup and restore all settings as a JSON file
Encrypted storage — Conversations stored locally with encryption
Text to speech — Listen to AI responses
Linux Sandbox — On Android, the AI can run shell commands, scripts, and tools in a secure sandboxed Linux environment
Image attachments — Attach images to any conversation
Linux Sandbox (Android)
On Android, Kai includes a built-in Linux environment that the AI can use to execute shell commands, run scripts, and operate tools on your behalf. This turns Kai from a chat-only assistant into one that can take real action — installing packages, processing data, running Python scripts, and more.
Powered by Alpine Linux — A lightweight ~3 MB download sets up a full Linux userland via proot, no root required
Optional packages — One tap installs bash, curl, wget, git, jq, python3, pip, and Node.js
Interactive terminal — A built-in terminal lets you run commands manually alongside the AI
Secure — Everything runs sandboxed inside the app with no access to the host system
Chat — User sends a message. The AI responds, calling tools (memory, web search, shell, etc.) in a loop until it has a final answer.
Memory — The AI stores and recalls facts, preferences, and learnings. Memories that prove useful (5+ hits) can be promoted into the system prompt permanently.
Heartbeat — A background self-check runs every 30 minutes. It reviews memories, pending tasks, and emails. If something needs attention, it notifies the user. Otherwise, it stays silent.

All popular servers are free and require no API key. MCP servers auto-reconnect on app startup.
Integrations
Splinterlands Auto-Battle (Android & Desktop)
Kai can automatically play Splinterlands Wild Ranked battles. Configure one or more LLM services in priority order, add your Hive account, and hit Start -- Kai will continuously find matches, pick teams using LLM-powered strategy, and submit them on-chain. Falls back to a simple greedy picker if all LLM services fail. Available in Settings > Integrations.
The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond.
A Claude Code plugin that automatically captures everything Claude does during your coding sessions, compresses it with AI (using Claude's agent-sdk), and injects relevant context back into future sessions.
