Lumo AI by Proton is a privacy-first AI assistant built for secure, confidential interactions. Key features include end-to-end encryption for all chats, ensuring data remains private and inaccessible to Proton. Unlike many AI tools, Lumo does not store conversation logs or use them for model training, upholding a strict zero-access privacy policy. It’s accessible via web or mobile apps, with or without a Proton account, and offers both free and paid plans to suit different user needs.
