Swiss-based company Proton, renowned for its secure email service, has launched Lumo, a standalone AI assistant designed as a privacy-first alternative to offerings from major tech giants.
Lumo is capable of summarizing documents, writing code, drafting emails, and responding to web queries. Built exclusively on open-source language models, the service is hosted in Proton’s European data centers. All interactions are protected by end-to-end encryption with a "zero-access" policy, ensuring that neither Proton nor third parties can access or store user messages.

Users can try Lumo without registration via its web client or mobile apps, though with usage limits. The Lumo Plus subscription, priced at $12.99 per month, removes these restrictions and allows for larger file uploads.
