Privacy in AI assistants has become a growing concern for users, especially following the widespread adoption of tools that record huge amounts of personal information. In this context, Proton has presented a new proposal which, according to the company, breaks away from the dominant trend in the sector: Lumo, its own AI chatbot focused on safeguarding its users' confidentiality.
Lumo bursts onto the market with a clear philosophy: ensure that the information of those who interact with the assistant remains under your control, far from the risks associated with mass data collection typically employed by other large technology companies. This commitment responds to a growing demand for solutions in which Personal data should not be used as currency or training material for future versions of AI..
A new approach to privacy for AI chatbots
Lumo's strategy is based on offering an experience where Each conversation is confidential and not stored on external servers. Unlike many popular services, the messages and questions the chatbot receives are not used to feed or improve AI models, and If the user decides to save a conversation, it is encrypted and can only be decrypted on your own device.
Proton, known for services such as Proton Mail, Proton VPN, Proton Calendar or Proton Drive, extends this strong commitment to privacy in LumoIn fact, the company highlights that does not record or share information with advertisers, developers, or authorities, positioning itself as a differentiated alternative compared to the majority of current AI assistants.
How does Lumo work and what does it offer?
Using Lumo is very simple And it's also transparent regarding data handling. The chatbot only accesses the internet if the user authorizes it via a specific web search button, thus preventing the collection of information without explicit permission. When it doesn't have the answer to a query, it clearly indicates this and suggests alternative methods for finding solutions, without trying to fabricate information or resorting to dubious sources.
In its functional aspect, Lumo allows you to perform private queries and searches, as well as analyze and improve documents., link directly to Proton Drive to work on files stored in the cloud, or act as a virtual assistant answering questions and providing recommendations. All with the guarantee that Nothing is stored on the server, nor is it used for personalization or AI training purposes..
End-to-end encryption and user autonomy
One of Lumo's strengths is end-to-end encryption., implemented in such a way that not even Proton can access users' conversations. Each profile has a unique encryption key associated with it, and the company emphasizes that Its open source architecture has been audited and recognized by millions of users in other brand solutions.
La absence of records and local data management They avoid the risk of leaks or unauthorized access. Furthermore, the company emphasizes that the chatbot does not collaborate with other technologies or transfer information to third parties under any circumstances.
Transparent and European AI models
Lumo operates entirely on European Proton servers and employs several large open source language models (LLMs), such as Mistral Nemo, Mistral Small 3, OpenHands 32B, and OLMO 2 32B, adjusting the selected model according to the query performed. For example, for technical or programming questions, Lumo automatically selects the most specialized model..
Transparency is another of the maxims this platform strives to uphold, as it does not use unclear proprietary engines or delegate processing control to third parties. The architecture and operation of the models are thus exposed to greater public scrutiny.
Availability, languages and prices
Lumo can be used from the web lumo.proton.me and also through apps for Android e iOS. The chatbot is available in 11 languages, including Spanish, and offers three modalities to adapt to the needs of users:
- Free use without a Proton account, limited in number of queries and without access to conversation history.
- Free for registered users, with more weekly questions, encrypted history, favorites, and the ability to upload small documents.
- Lumo Plus, a premium service with a monthly fee, which allows unlimited access, advanced history, and uploading of larger files.
In the functions section, it is not yet possible to create images or videos from text, although The platform is planned to gradually evolve towards new tools.
Proton's position, reflected in several official statements and in statements by its CEO Andy Yen argues that the future of AI must respect user privacy. as a fundamental principle, especially when handling sensitive data that is much larger than that processed in traditional search engines.
Therefore, Lumo positions its proposal in a market in need of responsible alternatives, placing confidentiality and personal control of information at the center of the AI experience. The user can interact with a powerful and versatile assistant knowing that Your data remains at all times under your exclusive control.
