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.

The idea behind Lumo is that while AI can provide significant opportunities for users and businesses, it also introduces new risks related to personal data collection.

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.
