## Lumi AI Description
Looking for a more personal AI companion you can actually keep with you?

Lumi is a private, on-device AI companion built to work right from your pocket. Chat without relying on the cloud, shape Lumi’s personality to fit you, and enjoy conversations that stay on your device.

With Lumi, you can:

Chat with a personalized AI companion
Use Lumi offline when Wi-Fi or service is unavailable
Keep your conversations private and on-device
Choose a personality or create your own custom one
Talk with Lumi in a dedicated voice mode
Share photos and documents for Lumi to understand
Lumi now runs on Gemma 4, making it much more capable, more natural to talk to, and more useful for everyday conversation.

Because Lumi runs locally, it needs serious power under the hood. Lumi is a large download and requires a device with 6GB or more of RAM.

Supported devices include:

iPhone 12 Pro or later
iPhone 14 or later
iPhone 17 or later unlocks the more powerful Ascended Lumi
iPad and Apple Vision Pro are supported too

This major update for Lumi makes a big step toward making it feel truly useful every day. More improvements are on the way as Lumi becomes more agentic, and I’d love to hear how it works for you.
