Proton, the company behind the encrypted email service Proton Mail, has launched an AI assistant aimed at preserving user privacy. This helps ensure that Proton can’t share user data with advertisers or governments, or use it for training large language models, Proton says. Users can link Proton Drive files to Lumo as well, which are supposed to stay end-to-end encrypted when interacting with the chatbot. Proton positions its AI chatbot as an alternative to the ones offered by larger companies, like OpenAI’s ChatGPT, Meta AI, Google’s Gemini, and Microsoft Copilot. The AI chatbot will field requests through different models depending on which is better-suited for the query.
