Proton has introduced Lumo, an AI chatbot designed with a strong emphasis on user privacy. Unlike many AI services that collect and utilize user data, Lumo ensures that all conversations are end-to-end encrypted and not stored on Proton's servers, preventing unauthorized access.
Key features of Lumo include:
Zero-Access Encryption: Conversations are encrypted in such a way that only the user can decrypt and read them, ensuring that Proton cannot access or utilize user data for training purposes.
Open-Source Technology: Lumo operates on open-source language models, providing transparency and allowing users to verify the chatbot's privacy and security measures.
European Data Centers: Hosted in Europe, Lumo benefits from robust privacy protections, free from Big Tech surveillance and outside of US jurisdiction.
Lumo is accessible via a web client and mobile applications for Android and iOS. Users can interact with the chatbot without creating an account, and it supports functionalities such as summarizing documents, generating code, and drafting emails. For enhanced privacy, web search capabilities are disabled by default, and if enabled, Lumo uses privacy-friendly search engines like Brave or DuckDuckGo.
Proton offers a tiered access model for Lumo:
Guest Access: Free, with limited queries and no chat history.
Lumo Free: Includes encrypted chat history, small file uploads, and limited favorites.
Lumo Plus: Priced at $12.99 per month, offering unlimited chats, extended chat history, unlimited favorites, and large file uploads.
By prioritizing user privacy, Proton aims to provide a secure and transparent AI chatbot experience, setting Lumo apart from other AI assistants in the market.
