Lumo is a privacy first AI chatbot for users who value the security of their private chats. It handles the usual jobs you’d expect from a chatbot, like answering questions, summarising reports, drafting text, planning tasks, searching the web and generating images, but the difference is what happens to your conversations. Chats are stored with zero-access encryption, so only you can read them, and they are never used to train AI models or build ad profiles.
Lumo is also open source, so anyone can check those claims for themselves. To get started, just open the web app and start typing, or sign up for a free Proton account if you want your history saved. Projects are handy for keeping related chats together, and you can link files from Proton Drive to give Lumo extra context for your work. The Free plan offers all the essential features but comes with usage limitations. Lumo Plus is an optional paid plan that adds higher usage limits, longer chat history and unlimited Projects.
