Lumo

Zero-access encrypted chats

Conversations are stored with zero-access encryption so that only you can read them; Proton says it cannot access them.

No training on your chats

Proton states that conversations are never used to train AI models, to target ads or to build a personal profile.

Web search

Built-in web search brings real-time information into answers. It is included in the free plan.

Files and Proton Drive

Link files and folders from Proton Drive to give Lumo context. The free plan uploads individual small files; Plus allows multiple large files.

Image generation

Turns a description into an image and lets you refine it through follow-up prompts.

Open-source code

Lumo's code is published as open source, which Proton says lets anyone verify that it is private and secure.
