For sensitive knowledge work, from client strategy to research you cannot put in the cloud: run models locally, sync with P2P encrypted sync, and share via ATProto while your data and identity stay private.
Sensitive knowledge work stays private on your machines, with secure collaboration built in.

The Atmosphere is the growing network of apps built on the AT Protocol (ATProto), an open decentralized protocol for social applications and portable identity.
For Tiles, this means social features do not need to live inside a closed platform. Shared chats, group conversations, public memory spaces, and community extensions can plug into an existing social graph already used by tens of millions of people. Instead of creating another siloed network, Tiles can build on open identity, portable accounts, and interoperable social interactions across the wider ATProto ecosystem.
For the full picture, see the official ATProto stack overview.
