How is Lumo different from other AI assistants?

Lumo is built with privacy in mind. Unlike other AI assistants, it does not collect your data to train its models or keep any logs of your conversations. Your data is protected by Proton’s strong privacy principles.

What can Lumo help with?

Lumo can answer questions, help you write messages, summarize content, explain technical concepts in simple terms, and more. It is designed to support you without compromising your privacy.

How are my chats stored?

Your chats with Lumo are stored with zero-access encryption, so Proton can't see your chat history. Only you can securely access your conversations by logging in to your Proton Account.

What languages does Lumo support?

Lumo understands and responds in multiple languages, including English, French, German, Spanish, Italian, and more. We’re working to add support for even more languages.
