Photo Paste Pounces In. Paste photos straight into your message on iPhone. Copy an image anywhere, then long-press the composer to open the native edit menu and drop it in. No Cat Naps Mid-Answer. The screen stays awake while Lumo writes, so you can read along without tapping to keep it alive. iPad Sidebar Clawed Back. In windowed mode on iPadOS 26, the system window controls no longer cover Lumo's sidebar button, so it's easy to reach again. Security Fur-tified. Behind the scenes hardening to keep your data where it belongs. Nothing for you to do.

About
Lumo is a zero-access encrypted AI assistant that keeps every conversation private. Your data is never logged, shared, or used to train models. Your chats are yours, and yours alone. Built by Proton, the privacy brand trusted by over 100 million people and the team behind Proton Mail, VPN, Drive, and Pass. THOUGHTFUL HELP FOR ANY TASK Lumo handles everything from quick questions to more complex work. Choose Fast for quick answers or Thinking for multi-step reasoning. FAST, POWERFUL WEB SEARCH Get precise, real-time answers in seconds. Lumo cites live sources so you can verify facts, dig deeper, and stay current on news, events, financial data, and more. CREATE AND REFINE IMAGES AND FILES Work with images and files just by telling Lumo what you need, from generating and editing images to analyzing documents. Connect your Proton Drive account for seamless access to stored files. AI THAT EVOLVES OVER TIME Lumo gets better every time you use it. Memory retains context and preferences across sessions, and you can set tones and styles to get the exact Lumo experience you want.

Switch between light and dark modes for a more comfortable experience throughout the day. GHOST MODE For conversations where you want maximum privacy, choose Ghost Mode.

PRIVACY YOU CAN VERIFY Lumo is founded on zero-access encryption with no server-side chat logs, and never uses your data for profit or model training.
