Lumen
A bright, easygoing everyday companion.
CharactersA familiar on your desk
Give your AI Agent a body on your desktop
Hermes is the included mind; DeskFamiliar is the body — a 3D companion that reads, writes, waits, and reacts. Codex and Claude Code connect out of the box, and developers can add any Agent through the open-source bridge.
An independent project — not affiliated with Nous Research or the official Hermes Agent team.

Tool calls you can see
Instead of hiding an AI agent behind a chat box or a plain activity log, DeskFamiliar brings the agent's work onto your desktop as a living visual presence.
Idle
Calm presence while nothing runs.
Reading files
Opens a book when the connected Agent reports a file read.
Writing files
Casts a writing spell when the connected Agent reports a write.
Waiting for confirmation
Looks to you when the built-in Agent asks for approval.
Completed
A clear, gentle finish.
Error
Visible feedback when something goes wrong.
The goal is simple: you should be able to glance at your desktop and understand what your agent is doing.
From tool call to character action
- 01
An Agent performs an action or tool call.
- 02
An adapter or bridge translates the event.
- 03
DeskFamiliar sends a shared character command.
- 04
The 3D character plays the matching action and returns to idle.
Key features
Built for people who want an AI agent that feels present, understandable, and accountable while it works.
Ready-to-use Agents. Open bridge.
Hermes Agent, Codex, and Claude Code work out of the box. Developers can add any Agent through the open-source bridge.
Tool calls you can see
Agent activity becomes readable character states — idle, reading, writing, waiting, completed, error — visible at a glance.
Permission-aware built-in Agent
The built-in Agent uses read-first defaults, asks before file writes and commands, and never offers an all-access mode.
