Lumo Description

Lumo is an AI assistant focused on privacy, designed to harness the capabilities of generative AI while ensuring complete confidentiality in your conversations. Created by the privacy specialists behind Proton Mail and VPN, Lumo guarantees that your discussions are private, with no logs stored on its servers, and all saved conversations encrypted with zero-access encryption, which means that even Proton cannot access them. With an open-source framework, the service is both transparent and verifiable, allowing users to engage with it confidently. You can inquire about various topics with Lumo, whether it's summarizing documents, rewriting emails, assisting with coding, translating text, brainstorming ideas, and much more, all without worrying that your data will be used for training models or shared with outside parties. Conversations are protected with end-to-end encryption, and if you enable the AI’s web search feature, it utilizes privacy-conscious search engines. Accessible without the need for registration and available through both web and mobile applications, Lumo provides options for both free and premium plans. With its commitment to user privacy, Lumo stands out as a reliable choice for anyone concerned about the security of their information while interacting with AI.

    Outstanding!

    Edited: Oct 06 2025

    Summary: Excellent 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.

    Positive: Easy 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.

    Negative: None found yet. Been using only a couple of months - but had tried ChatGPT, and CoPilot before.
