Proton's privacy-focused Lumo chatbot encrypts all your conversations

Proton has released a new AI chatbot called Lumo, which offers a private alternative to big tech's offerings. Lumo uses zero-access encryption, meaning only the user's device can unlock their content, and Proton cannot view or share their data. This ensures that user data is not misused or used to train future AI models. Lumo's features are similar to those of ChatGPT and Claude, but with a focus on privacy. It can search the web to answer questions, but this feature is turned off by default to protect user privacy. Users can also upload files, but Lumo won't save any information. Lumo is powered by open-source systems and filters requests through the best-suited model. The chatbot is free to use with a weekly query limit, and a $13 per month Plus plan offers unlimited usage and additional perks. Lumo is available on the web and as Android and iOS apps, and users don't need a Proton account to start a conversation. Proton aims to provide a private and secure AI assistant experience with Lumo. Overall, Lumo offers a unique blend of AI capabilities and privacy features that set it apart from other chatbots.
