Description

Proton Lumo is a privacy-first AI assistant developed by Proton, the team behind Proton Mail and Proton VPN. Lumo is designed to provide the benefits of AI without compromising user privacy or data security. Lumo doesn't use chat data to train its models. All conversations are protected by zero-access encryption. Proton itself cannot decrypt or view the content.

Lumo is built on open-source technology. The AI models used by Lumo are open-source or at least open-weights. Lumo is accessible without requiring an account, though signing in with a Proton Account unlocks additional features such as encrypted chat history, unlimited chats, and the ability to create Projects.

Recently, Proton has faced criticism for false claims regarding the privacy claims for their new video conferencing service Proton Meet. While this issue does not directly relate to Lumo, it makes Proton and thereby Lumo less trustworthy.
