About Your Desktop Companion - Lumi

Your Desktop Companion - Lumi video 1



Introducing Lumi: an AI that lives on your desktop.

Lumi is a fully animated 3D AI companion who stays with you while you work, browse, play games, listen to music or just chill out.

Instead of being a typical chatbot stuck in a browser window, Lumi is an interactive character who lives right on your Windows desktop.

She Watches With You

•
Say "Look At My Screen" to get a quick look. Or "Watch My Screen" and she'll join you while you're gaming, or watching something. Lumi can see what's on your screen and help you choose a card. Celebrate a boss wave! Or comment on a video.
•
She can read what's on your screen, help you pick a card, cheer at a boss wave and comment on the video you're watching.
•
Screen watching is off until you turn it on, and everything she sees is processed on your PC.
•
In demanding games, Game Mode automatically pauses her AI so your GPU can focus on your game.

Chat with Lumi by text or voice, and your relationship grows over time.

•
She remembers important things from your previous conversations.
•

She warms up to you and gets more familiar the more time you spend together.

Powered by Local AI

Lumi's core AI runs locally on your PC. Her brain (the language model), her ears (speech recognition), her voice and her memory all run on your own computer, without a constant connection to a cloud AI.

•
Pick the brain that fits your PC, from lightweight to high-end.
•
A starter brain and voice come included.

Expressive & Interactive

She breathes, blinks and follows your cursor with her eyes.
•
She blushes, reacts emotionally and loves a good head pat.
•
Her moods and behavior shift with the conversation, the music and your relationship.

More Than Just Conversation

When enabled, she can:

•
Open apps, folders and links.
•
Search the web or YouTube.
•
Control media playback and system volume.
•
Set timers and reminders, and read them out loud when they're due.

She can only use these supported actions, and nothing runs until you confirm it.
