Your AI conversations,
entirely yours
AI that learns you,
not from you
Kani is an AI chat assistant built from the ground up to be fully private. It builds context from all your conversations — exclusively on your device — delivering a richer, more personalized experience without ever exposing your data.
The uncomfortable truth: AI companies are increasingly using your private conversations to train models, target you with ads, and share insights with third parties. Your most personal thoughts become their product.
We built Kani differently. Your personalized context never leaves your device. No training on your data. No ads. No third-party access. Just powerful AI that respects your privacy.
Your data stays
on your device
Unlike cloud-based AI assistants, Kani keeps everything local. Your conversations, your thoughts, your privacy — all stored securely on your Mac, never on our servers.
Local-first storage
All data lives on your Mac
End-to-end encryption
Sync securely across devices
Zero server storage
We never see your conversations
Full transparency
See exactly what's sent to AI providers
Switch anytime
Your conversations and context travel with you — not locked to any single model or provider.
Every AI model,
one conversation
Every week, new AI models launch from labs around the world. Switching usually means losing all your conversations — or painstakingly exporting and importing your data. With Kani, your context stays local. Switch models anytime, even mid-conversation, without losing a thing.
- Switch models mid-conversation instantly
- Your context and history stay with you, not the provider
- Compare responses from different models side by side

Kani
Japanese for "crab"
Who is Kani?
Kani means "crab" in Japanese. Like its namesake, Kani carries your home — your memories, your context — wherever you go. And like a crab's shell, it protects what's vulnerable: your private thoughts stay yours, guarded by design.
We're a team of entrepreneurs, programmers, activists, and parents — convinced that technology can be a powerful tool to help us do amazing things. But we're also conscious and concerned about how it's currently being exploited in dangerous ways. That's why we built Kani.
A thinking partner that remembers everything and shares nothing.
