Introducing Lumo, the AI where every conversation is confidential
Proton, the company behind the encrypted email service Proton Mail, has launched an AI assistant aimed at preserving user privacy. The new chatbot, called Lumo, can summarize documents, generate code, write emails, and more, while storing data locally on users’ devices. Proton says it will protect this information using “zero-access” encryption, which grants users an encryption key that only they can use to view their content, preventing third parties, including Proton, from accessing the information. This helps ensure that Proton can’t share user data with advertisers or governments, or use it for training large language models, Proton says.
