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's new AI assistant Lumo promises to keep user data private with zero-access encryption, no logging, and an incognito mode.

Proton's new AI chatbot Lumo does something the other top AI chatbots don't -- keeps its grubby paws off of your private data.
