Proton, the Swiss company renowned for its privacy-focused services, has taken another significant step in the AI landscape.
Its product, called Lumo, stands out in a crowded field of AI chatbots by prioritizing user privacy above all else. Built on open-source language models such as Nemo, OpenHands 32B, OLMO 2 32B, and Mistral Small 3, it operates without tracking conversations, storing chat histories beyond what's needed for immediate use, or employing user data to train models.
Every interaction remains confidential, protected by zero-access encryption: a natural extension of Proton's long-standing commitment to data security.
This makes Lumo an appealing alternative for anyone wary of mainstream AI tools that harvest personal information.
And this time, it's releasing what it calls the 'Lumo 1.3.'
Announced via their official account on X, this update also introduces a standout feature called 'Projects,' which according to its support page, is a dedicated, fully encrypted workspaces designed to transform how users handle ongoing tasks with their private AI assistant.

The highlight of version 1.3 is the introduction of Projects, which allow users to create focused, persistent environments for specific endeavors.
Whether users are drafting a comprehensive report, managing university coursework over a semester, planning yearly goals, or tackling recurring workstreams, Projects bundle together related chats, uploaded files, custom instructions, and context in one secure space. This eliminates the frustration of repeatedly explaining background details or restarting conversations.
Everything stays in sync across devices and sessions, enabling Lumo to provide more relevant, continuity-aware assistance as your work evolves.
Integration with Proton Drive enhances the functionality further, letting users seamlessly upload and reference files or entire folders directly from their encrypted cloud storage.
This creates a cohesive, private workflow where sensitive documents can be analyzed, summarized, or built upon without ever leaving Proton's secure ecosystem. The emphasis on privacy remains unwavering: each Project operates as its own isolated, encrypted environment, ensuring no data leakage or unintended sharing.
Accessibility is another strong point of the update. Lumo 1.3 rolls out to all users immediately, with free accounts able to create one Project to get started. For those needing more flexibility, such as unlimited Projects, quicker response times, access to the most advanced underlying models, and unlimited chats, upgrading to Lumo Plus provides the full experience.
Businesses and teams can opt for Lumo Professional, which extends these capabilities to collaborative settings while maintaining the same rigorous privacy standards.
Since its initial launch in mid-2025, Lumo has steadily evolved to become a more capable and user-centric tool, with previous updates improving intelligence, speed, and real-world awareness. The addition of Projects in 1.3 feels like a logical progression, addressing a common pain point in AI usage: the lack of persistent memory for complex, long-term work.
By combining powerful open-source AI with unbreakable encryption and thoughtful organization features,
Proton continues to carve out a unique niche, offering an assistant that truly works for users, on their own terms, and without compromising their personal data.
While it may perform less powerful than some of its rivals, Lumo wants to offer privacy as the main selling point. And Lumo 1.3 with Projects wish to streamline productivity while keeping everything securely under users' control.
