proton is a company famous for its encrypted email service proton Mail, and has just launched Lumo, a new AI chatbot that puts user privacy first.
Unlike popular chatbot such as ChatGPT, Gemini or Copilot, Lumo commits not to collect or store user data on remote servers.
The highlight of Lumo is the complete local storage of data on users' devices and the use of "zero- access" encryption, meaning even Proton cannot access data.
Users are provided with a separate encryption lock, ensuring that all personal information, chat content, and messages are completely protected from third parties.
Lumo is powered by many large open source language models, including Mistral's Nemo, Nvidia's OpenHands 32B, and OLMO 2 32B from Allen Institute for AI. Depending on the request, this chatbot will choose a suitable model to process the request quickly and accurately.
In terms of features, Lumo not only creates code, composes emails, summarizes documents but can also analyze submitted files without storing content.
Ghost Mode mode helps delete all chat session data immediately after the end, even on local devices.
If you need to search for information online, users can activate the web search feature that is turned off by default so that Lumo can use privacy-friendly search engines.
In addition, this chatbot also integrates seamlessly with proton Drive, allowing users to share end-to-end encrypted files directly into the conversation without worrying about data leakage.
Regarding the usage model, Lumo has both free and paid versions. People without accounts can ask 25 questions a week but cannot access their chat history. Free users can ask up to 100 questions/week.
The Lumo Plus package, priced at $12.99/month, unlimited chat uncks, encrypted history access, and other premium features.
As concerns about privacy are mounting, Lumo has emerged as a safe and responsible AI solution, suitable for users who prioritize security.
