Lumo by Proton is a privacy-focused AI assistant designed to help users interact with artificial intelligence while maintaining full control over their personal data. Unlike many mainstream AI chatbots, Lumo operates on open-source language models hosted in Proton’s European data centers, ensuring transparency and minimizing reliance on third-party providers. The app does not log conversations on its servers, and all chats are protected with end-to-end encryption, meaning even Proton cannot access user discussions.
Users can engage with Lumo for a variety of tasks, including document analysis, email rewriting, code generation, and answering questions using its built-in knowledge base. For additional context, Lumo offers a web search feature that utilizes privacy-friendly search engines, and allows users to upload files directly for analysis—content that is not retained after the session ends. Integration with Proton Drive enables users to securely access and analyze files stored in their encrypted cloud storage, all while maintaining confidentiality.
A standout feature is Ghost mode, which ensures that any active conversation disappears permanently when the chat window is closed, offering an extra layer of privacy for sensitive discussions. When logged in, chat history is saved with zero-access encryption and is accessible only to the user across their devices. The app is available via web browser as well as dedicated Android and iOS applications, and no account is required to start using basic features. For those seeking extended functionality, a premium tier offers additional capabilities such as unlimited queries and support for larger file uploads.
Lumo is positioned as an alternative for individuals prioritizing privacy in their use of generative AI, providing powerful productivity tools without the data collection practices common to other major AI assistants. Its core appeal lies in combining accessible AI capabilities with robust, user-controlled privacy features.
