oh, hello. Blue Luumi looking quietly pleased with herself

…

Blue Luumi wearing a pink bow and thinking

Small cat. Useful brain.

A useful little brain

Luumi can answer questions, help you work through ideas, remember things you ask her to remember, and create Apple Notes when you tell her to.

When she's thinking, you'll know—she takes the performance very seriously.

Quietly capable

More than an excellent circle.

Lives on your desktop

Drag her anywhere. She stays above your other windows and naps when you close the chat.

Actually useful

Ask questions, brainstorm ideas, create Apple Notes, and give her things to remember.

Make her yours

Change her colour and combine bows, collars, stars, and other accessories.

Local if you want it

Use the Luumi AI Gateway, or connect her to a local Ollama model.

Built with opinions

Helpful. Sassy. Suspiciously round.

Luumi has a brain, opinions, and an extremely strong position on whether she is a dog.

Hover over her and she purrs. Click her and she gets startled. Drag her around for too long and she may become furious and deploy a tiny claw.

Cloud or local

Your Mac. Your choice of brain.

Simple intelligence, included.Luumi is ready to help as soon as you open her.

Luumi works through the Luumi AI Gateway by default. Gateway conversations are sent to the selected cloud model for processing, but Luum doesn't track you or store your conversation history.

Prefer a fully local setup? Switch to Ollama in Settings and choose a model installed on your Mac. Luumi's saved memories remain on your Mac and can be inspected or erased.
