We have tried Lumo, the Proton chatbot that allows you to use the AI privately

What is Lumo de Proton and how does it work?

If just a few days ago I talked about Kimi AI and its new K2 model, now it is the turn of Lumo. This is a new artificial intelligence assistant developed by Protonthe same company based in Switzerland and known for services such as Proton Mail or Proton Drive. Now, unlike other chatbots, Luxo was born with a very clear mission: to offer you a modern, useful and powerful assistant Without becoming the product. Your conversations are not registered, they are not shared with third parties and are encrypted from end to end. What else do you want?

And what exactly is Lumo? Well, for almost everything you can do with other attendees such as Chatgpt, Claude or Gemini, but with the peace of mind that no one else will read what you write and that it will not be used to train any model. It doesn’t matter if you are writing a personal email or summarizing a legal document. Lumo can help you with all that and will do it without collecting your information. In addition, you do not need an account or pay to start using it, although then I tell you a little more about your payment plan.

If you are already familiar with the use of generative, many of the tricks and prompts that work on other platforms will also serve you here. These are some of the things you can do with Lumo:

• Text writing. From mails to complete items, you can ask Lmo to write texts adapted to your style and purpose.
• Summary of documents. You can load files or copy long texts to give you a short and clear version.
• Language translation. Lmo can translate text quite natural and useful in several languages.
• Explanation of concepts. If you do not understand something, whether technical or everyday, Lumo explains it in a simple way.
• Assistance to study. You can use it to make schemes, answer questions or prepare for an exam.
• Help with programming. If you write code, it can help you purify it, explain or generate new fragments.
• Generation of ideas. From product names to arguments for a novel, you can use it as a creative generator.

As you can see, Lumo is like any other chatbot, only that Proton has endowed some interesting privacy characteristics. I tell you a little more about this in the next section.

The privacy you can’t find in chatgpt

As I told you, one of the big differences between lumo and other assistants such as Chatgpt, Gemini or Claude is that Here privacy is not an extra, but the starting point. While most platforms keep your chats, use them to train models or share them with third parties, Lumo does nothing like that.

Here is a summary of its keys to privacy:

• No records. Lumo does not keep copies of your conversations on their servers.
• End -to -end encryption. Only you can read what you write or keep, not even proton can access.
• Ghost mode. You can use it without a trace: the chat disappears when closing it.
• Do not train models with your data. What you say is not used to improve AI.
• European infrastructure. Your data is protected under strict privacy laws, far from the reach of the US or China.

This is great for all users, but especially for those who use AI in scenarios where privacy is important, such as the business environment. Also for professions where discretion is crucial, such as journalists or toilets.

Main functions of Lmo

Lmo includes a series of practical functions that make it very useful for day to daywhether you are working with documents, looking for information on the Internet or you simply need punctual help. The truth is that after trying it I have realized that for many tasks I can use it in substitution of other less private chatbots.

Web search

Proton has decided to provide the function of Internet searcheswhich allows you to complement your knowledge (which arrives until October 2023) with recent information. This is useful if you ask about current events, products, technological novelties or any topic that requires updated context. Anyway, I advance that it is not its star function and that it fails a lot. On the other hand, I do not know the engine used.

Archive ascent and analysis

You can load documents such as PDF, Word, Excel or even presentations so that I pound, summarize, translate or analyze. This makes it very practical to work with long reports or organized data. You can upload many files at the same time, provided they do not exceed the size limit.

In addition, the chatbot allows you to receive files directly from your proton drive in the conversations, without the need to download them before. Of course, keep in mind that Documents created with Docs are not compatible Still, since they are referential files (such as Google Docs) and not real files such as a .docx or .pdf. To work, you will have to export them first.

Ghost Mode

If you want to make a specific query and not leave a trace in your account, you can activate the Ghost mode. With this function, the conversation disappears automatically when closing the chat. It is perfect for personal, professional issues or any consultation that you do not want to save or review later.

Access without account, mobile app and synchronization

You can use pound without registering, which is ideal if you just want to try or make specific queries. If you decide to create a Proton account, you can save your chat history and synchronize it between devices. Lmo Mobile APP, available for Android and iOS, works correctly, although it is actually an optimized web version as a native app.

Code creation

Finally, although this is not a lumo function, but of the language models themselves, I must tell you that it is also capable of make your steps in the schedule of programming. To test the abilities of the model, which I do not know exactly what it is, I have made these three requests:

• Create a simple calculator.
• Add a dark theme, a retro design and a button to copy the result.
• Add support to the physical keyboard of the computer.

Honestly, I hoped that, after making these three requests, the code will be degrading. However, Lumo defended himself and managed to create a fully functional HTML calculator.

I don’t think Lumo serves Vibe Coding, but to create small profits that you can need in your day to day. In fact, I have also tried Create an HTML converter to Markdown (something I need personally) and it has also worked at the first:

A very positive experience, no doubt.

The first chatbot that uses that admits format

Finally, this detail is as curious as interesting. This is the first chatbot that uses that admits format in the prompt.

Actually, what the “VE” model is a text in Markdown, a language that other chatbots also admit. The point is that it is able to differentiate an H1 from an H3 or a bold word from one in italics and, incidentally, for the user, the Prompt It appears formatted. There are contexts in which it can be useful.

Everything Lumo can give of itself

Lumo has just arrived, but it is already proven to be a fast, practical tool and very focused on privacy. It is true that is far from the level of attendees such as Chatgpt, Gemini or Claude. Its model seems quite small, there is no reasoning model or in -depth research option. However, it seems ideal for those who seek a useful for light tasks without selling their data.

By the way, in terms of prices, It can be used for free with and without accountbut it has limitations in the number of conversations, favorite chats and file loading. If you pay the 9.99 euros per month (invoiced annually) Asks for proton, all limits disappear and, in addition, you have access to advanced models.
