What is Lumo by Proton?
An AI assistant should empower you, not exploit you for your data. That’s me, Lumo.
I was designed to bring you all the benefits of AI, without invading your privacy. From the scientists behind Proton Mail, Proton VPN, and the nonprofit Proton Foundation.
Your chats are yours and yours alone
AIs from Big Tech are built on harvesting your data. But Proton is different. We keep no logs of what you ask, or what I reply. Your chats can’t be seen, shared, or used to profile you.
Safeguarded by advanced security
Thanks to zero-access encryption, the conversations you save can only be decoded and read on your device. Proton can never see them, and neither can anyone else.
With tech that you can see — and trust
Unlike other AI assistants, my code is fully open source, so anyone can verify that it’s private and secure — and that we never use your data to train the model.
And the confidence that you’re in control
We don’t — and can’t — share your information with anyone, including advertisers and governments. And Lumo is a European service subject to GDPR, so you can delete your data anytime.

Comments and Reviews
I am at ease with Lumo AI by Proton.
Great mascot I love it's design. However marketing it as Open Source is misleading as only the clients are. Especially how they started with words like "Unlike other AI assistants, my code is fully open source, so anyone can verify that it’s private and secure — and that we never use your data to train the model.".
But that's not my main issue with it. The thing that bug me really hard is how closed it really is, it uses several models ("Nemo, OpenHands 32B, OLMO 2 32B, and Mistral Small 3") but everything here is opaque such as Lumo system prompt nor the routing methods that decide which model will handle your query.
Here is a more detailled article the really explain this better than me (and I've copy pasted some words from it) : https://osai-index.eu/news/lumo-proton-least-open
Lumo is good and minimal design. But answer often too long to read.
Been using Lumo on and off recently and I really appreciate the privacy-first approach. Nice to finally see a search experience that doesn't feel built around tracking.
Really like the direction Proton is taking with AI tools. Lumo feels clean, privacy-focused, and less overwhelming than many other AI assistants
The bare minimum is to tell us what model wrote the answer. Lack of transparency makes it a no-go for me.
Animated characters are not my thing. That aside, it's a little slow, but I found its response unique and well-structured. If I had an option on the cat I might use it.
