Sealed hardware
Open-weight models answer inside sealed hardware. Not even Thinkr can read the chat.

Private AI built on encryption and zero knowledge.
How your chat stays private
AI is where you think out loud. Every chat takes this path by default, and not even Thinkr can read it.

Your chat is locked on your phone or laptop before it goes anywhere.

The model runs inside sealed hardware. Your device checks the seal before it sends a word.

Thinkr never holds your keys. Your history stays on your device, encrypted with a key only you hold.
Models
Open-weight models run in sealed hardware by default. The rest run with zero data retention, and every label says who can read the chat.

Claude, GPT, Gemini, and Grok run with zero data retention on every request. Their label says that the provider can read the chat.
By design
No trackers, no ads, no training on your chats, and no chats on our servers.
Thinkr
Your thoughts stay yours: sealed from the first word, labeled for every model, and zero by design.
