What is Lumo?
Lumo serves as a privacy-centered AI assistant that leverages generative AI's potential while prioritizing the confidentiality of your discussions. Developed by the privacy experts behind Proton Mail and VPN, Lumo ensures that conversations remain confidential, with no logs kept on its servers and all stored interactions protected by zero-access encryption, which prevents even Proton from accessing them. Boasting an open-source architecture, this service offers transparency and verification, enabling users to interact with it freely and securely. You can discuss a wide range of subjects with Lumo, from summarizing documents and rewriting emails to aiding in coding, translating text, brainstorming ideas, and more, all while maintaining peace of mind that your data won't be utilized for model training or shared externally. The platform secures conversations through end-to-end encryption, and, if you activate the AI’s web search feature, it relies on privacy-focused search engines. Lumo is easily accessible without requiring registration and is available on both web and mobile platforms, offering users a choice between free and premium plans. Its strong emphasis on safeguarding user privacy makes Lumo an appealing option for those who prioritize the security of their personal information when engaging with AI technology. Additionally, Lumo continually updates its features to enhance user experience and maintain the highest standards of privacy.

Outstanding!
Updated: Oct 06 2025SummaryExcellent experience. Their "kitty kat" mascot is cute and there whenever I open it, and their answers are very conversational and on target for what I was seeking.
PositiveEasy to use and ask questions. Answers are easy to understand, helpful and on target. Totally PRIVATE, they are NOT earning money by selling my data - thus I pay for it.
NegativeNone found yet. Been using only a couple of months - but had tried ChatGPT, and CoPilot before.
