Proton has rolled out a major upgrade to its AI assistant, Lumo — bringing substantial performance improvements while doubling down on user privacy.
Lumo 1.1 delivers faster responses, stronger reasoning, more accurate contextual understanding, and better code generation — all without storing or training on user conversations.
Performance That Rivals the Giants
Proton claims a:
- 200% improvement in multi-step problem-solving
- 170% gain in contextual understanding
- 40% boost in generating accurate code
These figures put Lumo firmly in the conversation with big-name AI assistants — but with one major difference: data privacy.
Private by Design
Most AI assistants come with an unspoken tradeoff: convenience for your data. But Proton refuses to play by those rules.
Lumo operates on strict privacy principles:
- End-to-end encryption by default
- No logging or storing of user conversations
- No use of user data for training the model
- Zero internal visibility — not even Proton can read your messages
It’s like having a conversation in a locked room only you can access.
Open Source for Transparency
To support its privacy-first claims, Proton has made its mobile apps for Lumo open-source. This move invites the security community to audit the codebase and verify that Proton is practicing what it preaches.
It’s not just about trust — it’s about proof.
The Price of Privacy
There is one caveat. While Lumo offers a free tier, the best performance is reserved for Lumo Plus, a paid plan that unlocks unlimited usage and full capabilities.
Proton’s bet is clear: some users will happily pay for powerful AI that doesn’t mine their conversations or sell their data.
A Growing Challenger in the AI Wars
Lumo’s latest update marks an important milestone. It shows that privacy and performance don’t have to be mutually exclusive — and that there’s room in the AI landscape for tools that respect both users and their data.
In a world where every search, message, and prompt feels like it’s being recorded, Proton is charting a different path — one that’s worth watching.
