Proton Lumo
Proton Lumo is a secure generative AI environment that operates independently of Proton's email service. It provides a private, standalone interface for interacting with large language models, ensuring that chats remain encrypted and are never used for model training.

About
Proton Lumo positions itself as a direct, privacy-preserving competitor to ChatGPT, offering a standalone workspace rather than just a plugin for Proton Mail. Users can access Lumo via a dedicated web interface or mobile app to brainstorm ideas, draft content, or analyze text without their data ever feeding the algorithm. This flexibility makes it suitable for a wider range of use cases beyond email, such as coding assistance, creative writing, or confidential business strategy.
Central to Lumo is Proton's signature "Zero-Access" encryption architecture. Even though the AI processes your queries, the session data is encrypted on the client side before being stored, meaning Proton cannot read your conversation history. The platform aggregates various open-source models (allowing users to toggle between engines like Mistral or Llama depending on the task) and acts as a secure shield, stripping away IP addresses and personal identifiers before the query reaches the model.
By decoupling the AI from the mailbox, Lumo caters to users who need a general-purpose AI assistant but refuse to accept the data-harvesting terms of US-based tech giants. Whether used for personal queries or sensitive professional work, Lumo guarantees that your inputs vanish from the processing pipeline the moment they are answered, ensuring total data sovereignty.
