Privacy‑First AI that Keeps Your Secrets Safe

Proton’s new Lumo 2.0 builds on the success of its first AI helper, attracting millions last year, but takes a bold step away from cloud‑based models.

Core Design

Zero‑Access Engine – All chats, images, and context are locked in end‑to‑end encryption. Only the user can decrypt them; Proton never sees the data, so it cannot be reused for training or sold to advertisers.
Swiss Hosting – The system resides in Switzerland, shielded by strict privacy laws rather than U.S. government requests.

Performance Modes

Mode	Speed	Function
Fast	~75 % quicker on everyday queries	Quick answers
Thinking	Step‑by‑step reasoning for complex problems	In‑depth explanations

Image Capabilities

Upload photos for analysis or generate new images from text prompts.
All image processing remains encrypted.

Enhanced Web Search

Real‑time news, market data, and weather.
Sources are cited to reduce misinformation.

Product Evolution

Proton began in 2013 as a privacy‑focused email and VPN provider. Extending those values into AI aligns with the company’s mission: “As AI becomes part of everyday work and creativity, keeping privacy non‑optional is essential.”
