A native AI desktop environment with persistent semantic memory, 118 built-in skills, voice control, and automation workflows. Local-first. Privacy by architecture.
Kai is a persistent AI companion that lives in your macOS menu bar. It remembers everything, automates anything, and learns how you work over time — entirely on your Mac.
- Persistent Memory — Every conversation, preference, and detail is indexed and searchable by meaning, not keywords.
- Your Notes Train Kai — Everything you write becomes part of what Kai knows. No manual setup.
- 118 Built-in Skills — Media processing, PDF tools, web utilities, data conversion, system control, and more.
- Voice Control — Speech-to-text, text-to-speech, wake word detection ("Hi Kai"), continuous conversation mode.
- Automation Workflows — Visual Zap builder with conditional logic, triggers, and branching.
- Screen Awareness — Kai sees what you're working on for context-aware assistance.
- 100% Local — Your data lives in a local SQLite database. No cloud sync. No third-party storage.
Kai supports both cloud and local AI models:
- Cloud Providers: OpenAI, Anthropic, Google Gemini, Groq, Mistral, DeepSeek, and more.
- Local Models: Download and run models from HuggingFace on Apple Silicon via MLX. Fully offline, token-by-token streaming.
- Multi-Provider: Switch between models or providers at any time.
- Semantic Search — Find past conversations by meaning, not keywords.
- Fact Extraction — Kai automatically identifies and saves facts about you (name, profession, preferences, and more).
- Auto-Extraction — Every 10 messages, Kai runs a deeper analysis to capture key insights.
- Context Compaction — Long conversations are automatically summarized to keep responses sharp.
- Deduplication — 30-second window prevents duplicate entries.
