AI is accelerating some of the worst abuses of surveillance capitalism. AI is more personal and more pervasive than even search engines. Big Tech companies are putting AI in everything, training their models on your data, and building even more detailed profiles of you without your consent. We need a private alternative.

Whether you’re asking a personal question, drafting sensitive work documents, or just exploring ideas, Lumo helps you without keeping any logs of your conversations. Unlike AI tools that store, share, and leak your data (as ChatGPT recently did with 100,000 chats), Lumo delivers truly confidential AI through a unique combination of features:

- No logs: Lumo doesn’t keep any record of your conversations.
- Zero-access encryption: Any chats you save can only be decrypted on your device.
- No data sharing: Lumo’s no logs and encrypted architecture ensure we don’t have data to share.
- Based in Europe: Our legal jurisdiction protects you from surveillance when US or Chinese AIs cannot.
- No training: We don’t use your chats to train the models.
- Open source: Lumo is open source so anyone can verify it's private.

Anyone in the Proton community can use Lumo for free or upgrade to Lumo Plus for faster responses, unlimited queries, and better reasoning with our most powerful models. Because Lumo will always be ad-free and powered by our community, Lumo Plus subscriptions enable us to cover the operational expenses of AI and ensure we can continue to put your privacy first.
