Proton Launches Lumo: A Privacy-Focused AI Assistant with End-to-End Encryption
Privacy-centric tech company Proton has unveiled Lumo, its new AI assistant designed to put user privacy first. Unlike many mainstream AI chatbots, Lumo ensures that your conversations remain confidential and secure, setting a new standard for privacy in AI-powered productivity tools.
Key Features of Lumo
- No Account Required: Lumo can be used instantly without needing to sign up, making private access easy and frictionless.
- Zero Logging: The assistant keeps no logs of your conversations, so your chats aren’t stored or used for future training.
- End-to-End Encryption: All stored chats are encrypted, and only you can decrypt them on your device.
- Ghost Mode: For added privacy, Ghost Mode ensures conversations are deleted as soon as you close the chat window.
- File Upload Support: You can upload files to Lumo and receive insights or answers about their contents.
- Proton Drive Integration: Users with a Proton Drive account can connect with Lumo to access and interact with their cloud-stored files securely.
- Available Everywhere: Lumo is accessible via web client, Android, and iOS apps.

How Lumo Stands Out
Lumo is built on open-source language models and operates from Proton’s European datacenters. This provides users with a high level of transparency and aligns with strict European privacy regulations. Proton emphasizes that Lumo is not connected to U.S. or Chinese AI providers, so queries are never shared with third parties.
The company also highlights its commitment to privacy by stating that user data is never used to train its models. Instead, Proton relies exclusively on open-source models for research and development.

Seamless Privacy for Productivity
Lumo’s privacy features are designed for everyone, from business owners needing confidential document analysis to individuals seeking peace of mind in their daily digital interactions. The assistant’s integration with Proton Drive and its ability to process uploaded files make it a versatile tool for secure productivity.
Proton’s Growing AI Ecosystem
Lumo is the latest addition to Proton’s suite of privacy-first products. Previously, Proton introduced an AI-powered writing assistant for its Mail service that operates entirely on the user’s device, further demonstrating the company’s dedication to privacy in AI innovation.
