The company behind Proton VPN, Proton Mail and Proton Pass, has released an open-source AI chatbot that it says isn't trained on user data.

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.

This ChatGPT alternative encrypts your conversations and won’t use them to train AI. Proton is getting into generative AI with an assistant called Lumo, which it pitches as a more private alternative to ChatGPT.
