Why Tiles?
For sensitive knowledge work or personal tasks, your AI shouldn’t require you to trust a third party with your conversations and intellectual property. Run models locally, sync chats peer-to-peer with end-to-end encryption, and use social features, such as sharing chats, built on AT Protocol. Tiles gives you user-owned keys for your digital life with DIDs and UCANs, so your data and identity truly remain yours.
Use cases
Coworking spaces
Turn shared compute into private AI infrastructure. Let members use local models from their own devices while keeping identity and data private.
Researchers
Review literature, analyze datasets, and run agents in preconfigured, resumable research sandboxes.
Enterprises
Deploy private agentic systems powered by open frontier models. Secure users and agents with zero-trust authentication and authorization, simplify team management, and reduce infrastructure and model costs.
What's inside
Run polished local models
Embedded Pi agent harness for knowledge work, built around OpenAI’s 
gpt-oss-20b, with plugin support for reusable, skill-based workflows.
Own your identity
Tiles uses locally generated DIDs and UCANs for zero-trust authentication and authorization. This lets you own and control your identity across your digital life.
Use local models on remote devices
Securely run local models on a remote device like your home lab, peer-to-peer, from any device.
Sync chats across your devices
Encrypted peer-to-peer chat sync across your linked devices.
Share chats with friends
Create a public or private link to a chat session, published on Atmosphere and stored on your own personal data server (PDS).
Every chat is a sandbox
Resume or share chats as sandboxed microVM environments with friends or agents across devices.
Open source and free forever
Tiles is open source and forever free to use, dual-licensed under MIT and Apache 2.0. It is designed to be future-proof and continue working forever.
Designed for the Atmosphere
- Your online data lives on a Personal Data Server (PDS), and you choose who hosts it.
- Apps connect to you, not the other way around.
- No starting over when apps change or disappear.
What's the Atmosphere?
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.
