Proton’s Privacy Defender has deployed an upgrade to AI assistant Lumo, which promises faster, more intelligent responses.
AI assistants can be extremely helpful in drafting emails, planning trips, or satisfying random curiosity, but there is always a nagging feeling that every question you ask, every idea you explore is recorded, analyzed and fed into a large corporate machine. I’m trading a bit of privacy for a bit of convenience.
Lumo is now much smarter. Proton calls it version 1.1, and the main point is that almost everyone has better AI assistants. It offers faster, more detailed answers and is much more up-to-date on what’s going on in the world.
For certain indicators, Protons claim a 200% improvement in Lumo’s ability to “infer” through complex problems. It’s a tricky multi-step thing that other AIs tend to get lost. Plus, Proton says that AI assistants are 170% better at realizing the context of what you’re looking for. For coders there, there’s a 40% boost to generating the correct code.
But here’s a really important part. It does all this without sn-searching you.
Unlike major players, Proton’s entire approach to AI is built around privacy. When you chat with most AI, you are having a conversation in a room full of people taking notes, essentially. With Lumo, you are in a locked room. There is a key. Your conversations are encrypted so that no one in the proton can read them. They don’t save your chats and don’t train AI using your personal conversations.
To prove its privacy claim, Proton has opened sourced the code for its AI Assistant mobile app. This means that Proton is looking under the hood and making sure everyone is running in the way the Lumo engine claims. It’s about building trust, not just demanding it.
So, what’s the catch? Well, I recommend signing up for Lumo Plus for absolute best performance and unlimited use. And that’s exactly the point. Proton bets some of us pay some quids for services that respect our privacy rather than getting a “free” service where our data is the real price of admission.
This latest update from Lumo is a statement from Proton, who argues that there is no need to choose a powerful AI and a privacy-respecting AI. They are still underdogs fighting the tech giants, but with this update, they have shown they are candidates worth watching.
