This has nothing to do with Qubes-os, but I know that many here use ProtonVpn and/or protonMail.
I just found that proton is developing its own AI. It seems available even if we don’t have a proton account.
I recently had the chance to use Lumo, and I think it’s a solid tool. However, I don’t believe it can compete with OpenAI or DeepSeek at this point. From my experience, the model feels a bit limited, which makes sense given that it hasn’t been trained on our specific data. I really like the concept, though, and I’m curious to see if it can evolve in the future to match or even surpass its competitors.
People should be aware that chats with the LLM can only be processed in clear text, and that this processing is done in the EU, not in Switzerland.
That’s why I’m happy that an AI tool comes from Switzerland.
And what’s more, from a society like proton.
What I mean is that Lumo is hosted in the EU, not Switzerland
What do you mean about that? I heard some voices that EU want to implement a chat control but I don’t know if the law is passed or not.
All conversations are encrypted and there is no log.
If I have to trust an online AI compared to gpt, mistral, llama or deepseek. I think I would be at lumo.
Nothing is perfect online, but AIs offered by companies like Proton appeal to me much more than others
Like their vpn’s servers in china or russian lol
In any case, to put it simply, I think it’s rather good news in the world of artificial intelligence

I’m not saying people shouldn’t use Lumo, I’m only sharing privacy considerations that Qubes users may want to be aware of:
- Text used as input to an LLM, as well as the text the LLM produces, must be in clear text (unencrypted) at the time of processing. Proton states that chat history is then encrypted using the same “zero-access” encryption that is used to store emails that were received unencrypted. This also means that any documents you attach in-chat from Proton Drive or via upload are also processed unencrypted. Proton promises that chats are never used for training and that logs are destroyed, but this is only a promise and not a cryptographic guarantee.
- Lumo processing is done on servers in the EU, and so EU privacy law applies, rather than Swiss privacy law.
As long as users are aware of these details, Lumo is a much more private option than other LLM web services.
I’ve already reviewed the main page of Lumo AI before I used it, so I’m familiar with Proton’s statement. However, thank you for reiterating it.
Hi @Tezeria, as you recognized yourself this thread is off-topic. Please refrain from starting off-topic threads. Will close this thread now.
