Now live: Lumi 3.0

Voice Mode. Image + document chat. Core + Ascended. Private AI, finally done right.

Lumi

Your AI belongs on your phone.

Lumi 3.0 is private, on-device AI for iPhone and iPad with voice chat, image and document understanding, and a personality you’ll actually want to talk to.

Why Lumi hits different

  • Private means private. Lumi runs on your device, not in a browser tab pretending to be personal. No cloud chat logs. No account required. No data collection.
  • Talk to it like a person. Voice Mode makes Lumi feel conversational instead of transactional.
  • Show, don’t just tell. Drop in photos, screenshots, PDFs, and files and let Lumi work from what’s actually in front of you.
  • Choose your speed. Core is fast and lightweight. Ascended goes deeper when you want more nuance and reasoning.
  • It has a point of view. Lumi can be warm, sharp, sarcastic, coach-like, or fully customized to your style.

Built for Apple hardware

Lumi 3.0 is optimized for Apple Silicon and built around local-first AI. It feels fast, stays personal, and keeps working when the cloud isn’t the point.

Made by an indie developer

Lumi is built by one developer with a simple belief: the future of AI should be useful, local, and under your control.
