La Privacy concerns about artificial intelligence assistants is growing, especially due to the way several large technology companies store and use their users' data. In this context, a particularly significant development has emerged: Lumo, the new chatbot launched by Proton, the same team responsible for Proton Mail and other products focused on protecting personal information.
Proton presents Lumo as a AI assistant that operates under strict confidentiality and security standardsSince its launch, the platform has been defined by not requiring any type of personal data to operate, thus avoiding exposure to exploitation or data collection practices by third parties.
Privacy first: encryption and total control
One of the pillars of Lumo is the use of zero-access encryption technologyThis system ensures that only the user has the necessary password to read their conversations and files, excluding even the Proton team itself. Unlike other assistants, here no logs are stored on central servers; everything saved can only be decrypted and accessed from the user's devices.
This privacy architecture also extends to the documents and files that are analyzed or managed from Lumo. The data are not shared with advertising companies, governments, or third-party vendors, nor are they used to improve AI language models. Furthermore, Proton's own servers located in Europe reinforce its commitment to data sovereignty.
Lumo's main functions and unique features
Lumo allows you to perform tasks such as summarize documents, program code, write emails y search for information on the webAll of this without sacrificing any privacy: even the search function is disabled by default and, when used, uses search engines that respect user information.
Among its advanced capabilities, Lumo integrates directly with Proton Drive to analyze files without compromising security. It also features Ghost Mode, which makes conversations disappear completely after closing the chat, adding an additional layer of anonymity. It's also possible to share and view files without the platform retaining any information about them.
Based on open-source AI and European technology
The technology behind Lumo is based on large open source language models, such as Mistral Nemo, Mistral Small 3, Nvidia OpenHands 32B, and OLMO 2 32B developed by the Allen Institute for AI. Depending on the type of query (e.g., programming or writing), Lumo automatically selects the most appropriate model to deliver accurate answers, all while running on Proton's infrastructure in Europe.
Different ways to access and use Lumo
It is possible to use Lumo accessed from lumo.proton.me (link) or through their apps for Android e iOS. You don't need to have an account to try the assistant, although the number of weekly questions will be limited and chat history won't be saved. Those who already have a Proton account can enjoy an encrypted chat history, small file uploads, and other benefits, while the Lumo Plus subscription expands the boundaries of querying, storing, and analyzing large documents.
Since its launch, Lumo is already capable of answer queries in 11 different languages, including Spanish, and enriches Proton's offering alongside other services such as Mail, Drive, VPN, and Pass, all with the common denominator of privacy protection.
Responding to growing concerns about the use and exploitation of data by big tech companies, Lumo It is presented as a reliable and simple alternative For those looking for a useful and secure AI assistant, experts recommend continuing to use common sense and avoid sharing extremely sensitive information via AI, no matter how secure its encryption.
The development of Lumo responds to the objective of offer an effective tool without sacrificing privacy, thus setting itself apart from other assistants on the market. Proton's clear commitment to confidentiality, transparency, and total user control positions Lumo as a benchmark for those who value the protection of their personal data in today's digital environment.
