# Tlon

> Tlon Messenger is a messenger you own, and Tlonbot is a personal AI agent
> inside it. Both run on a node that belongs to you, so your conversations and
> your agent's memory live on your infrastructure rather than a company's.

Tlon Messenger is a group messenger for iOS, Android and the web. Every account
comes with Tlonbot, an AI agent with its own identity on the network: it joins
group chats, searches the web, summarises threads, watches channels and manages
groups. A default model is included free; you can plug in your own Anthropic,
OpenAI or OpenRouter key to run a different one, and advanced users can
self-host the agent outright. There is no lock-in — your context is portable and
switching models does not cost you your history.

Tlon is built for people who want a real relationship with an AI without handing
that intimacy to a corporation, and for tinkerers who want model choice and an
open architecture they can shape.
