Proton’s new encrypted AI chatbot, Lumo, puts your privacy first

Proton, a privacy-focused company, has launched an encrypted AI chatbot called Lumo. Unlike most AI chatbots, Lumo prioritizes user privacy. All user data is stored locally and protected with "zero-access" encryption, ensuring only the user has access to their content. Lumo can perform various tasks, such as summarizing documents, writing emails, and generating code, while maintaining user privacy. Web search is disabled by default but can be manually switched on to use privacy-friendly search engines. Lumo's AI model is based on open-source models from various organizations, and the most appropriate model is chosen for each task. Lumo is available as both a web service and an app, with a free version and a paid version that offers unlimited use and more storage space.
