Privacy-first technology company Proton, known for its encrypted email service Proton Mail, has launched Lumo, an AI-powered assistant designed with privacy at its core. Lumo stands out in a sea of generative AI tools by offering end-to-end encrypted conversations, giving users a secure and private alternative to mainstream AI chatbots such as ChatGPT and Google Gemini.
The move represents Proton’s growing ambition to expand its secure ecosystem beyond just email and calendar services and create trustworthy AI utilities tailored for users who prioritize data security and digital rights.
What makes Lumo unique in today’s booming AI landscape is its commitment to zero-access architecture and full message encryption, designed to ensure that no third party including Proton itself can access user conversations.
As concerns grow over how mainstream AI models collect and store data from millions of global users, Lumo sets a new benchmark. Unlike ChatGPT or Google’s Gemini, which log conversations (often for model training or performance improvements), Lumo does not store user queries in a retrievable form.
Lumo is currently available in beta for users on Proton’s paid plans (Proton Unlimited and Proton Visionary), with a wider rollout expected later in 2025. The assistant is accessible via the web and mobile apps and will soon be added to Proton Mail and Drive with contextual smart features.
With Lumo, Proton continues reinforcing its status as a leading European tech brand fighting back against Big Tech’s data-hungry dominance. The launch aligns with the company’s long-standing mission to build an internet where privacy comes first and not just as an afterthought.
As AI tools become a daily utility, Proton’s Lumo offers a refreshing and responsible way to use them without giving up control over your personal data. For those who prioritize confidentiality, security, and digital ethics, Lumo might be the AI assistant worth switching to.
