Lumo 1.1: Faster, Smarter AI with Unmatched Privacy

3 min read

Proton Lumo 1.1

Proton’s Lumo 1.1 delivers blazing speed, smarter context handling, and zero-access encryption. This is the privacy-first AI assistant businesses and individuals have been waiting for.

Why AI Needs a Privacy-First Alternative

Artificial Intelligence is now embedded in everything from customer support to research to personal productivity. But here’s the trade-off most people ignore: the majority of popular AI tools record your interactions, use them for model training, and sometimes even sell aggregated data to third parties.

For organizations handling sensitive data, that’s unacceptable. Privacy is no longer a luxury it’s a requirement. This is where Proton’s Lumo 1.1 sets itself apart.

Just like Proton Mail reshaped how we think about secure communication, Lumo is reshaping how we should think about AI: powerful, transparent, and truly private.

What Is Lumo 1.1?

Lumo is Proton’s AI assistant. It’s integrated into Proton’s suite of privacy-first tools and designed for people and businesses who need the benefits of AI without giving away their digital footprint.

With the 1.1 release, Proton focused on two things: performance and trust. The result is an AI that not only competes with big players like OpenAI and Anthropic but does so with a completely different philosophy.

Core Principles

No data harvesting: Your conversations are not used for training.
Zero-access encryption: Even Proton cannot view your data.
Open-source foundation: Built on models like Mistral Small 3, OLMO 2 32B, NEMO, and OpenHands 32B.
European hosting: Protected by GDPR and the world’s strictest privacy laws.

This is not just another AI chatbot it’s a statement: AI should serve you, not mine you.

Major Performance Upgrades in Lumo 1.1

Proton didn’t stop at making Lumo private it made it faster, smarter, and more reliable.

The 1.1 update comes with striking improvements:

170% stronger context comprehension → answers are sharper, more relevant, and far less generic.
40% more effective in programming tasks → better code suggestions and debugging support.
200% smarter at planning → multi-step reasoning, scheduling, and workflow execution.
Optimized reliability → reduced errors and faster response times.

In short, Lumo 1.1 is now capable of handling complex business use cases from project planning to analyzing sensitive documents without slowing down or leaking your data.

Why Lumo 1.1 Matters for Businesses

For professionals, the choice of AI tool is no longer just about cost or features. It’s about risk management.

Law firms can’t risk client documents being stored or reused by third-party AI providers.
Healthcare providers must comply with strict data regulations.
Finance and startups need strategic insights without exposing intellectual property.

With Lumo 1.1, companies gain an AI that’s safe to deploy in critical workflows because security isn’t bolted on as an afterthought, it’s the foundation.

Standout Features That Change the Game

Lumo 1.1 introduces features designed to give you full control over your AI experience:

Ghost Mode → Start a one-off conversation that’s immediately discarded. Perfect for ultra-sensitive queries.
Document Upload & Analysis → Upload contracts, reports, or research and get secure AI insights without leaks.
Encrypted Cross-Device Sync → Access your history across devices with zero-access protection.
Private Web Search Integration → Get enriched answers with Proton’s curated approach, not ad-driven scraping.

These aren’t gimmicks they’re practical features for professionals who need privacy as much as performance.

Pricing and Availability

Proton keeps things simple with two plans:

Free Plan: Core features, limited usage. Perfect for individuals exploring Lumo.
Lumo Plus: $12.99/month or $119.98/year. Includes unlimited chats, document uploads, history search, access to all models, and priority response times.

Compared to ChatGPT Plus ($20) or Claude Pro ($20), Proton offers competitive pricing but with the crucial addition of guaranteed privacy.

The Bigger Picture: Trust in AI

The release of Lumo 1.1 signals a bigger shift in AI adoption. As organizations begin to scale automation and decision-making with AI, the trust factor becomes non-negotiable.

Big Tech AI tools may offer speed, but they come with hidden costs: loss of control, loss of transparency, and loss of trust. Proton is positioning Lumo as the antidote an AI assistant that never compromises on user rights.

Bottom Line

Lumo 1.1 is more than an upgrade it’s a redefinition of what AI can be.

Smarter and faster with 170%+ performance gains
Safer with zero-access encryption
Transparent thanks to open-source foundations
Affordable with a free plan and a competitive premium tier

👉 If you value both performance and privacy, Lumo 1.1 is the AI worth trying today. And for teams that need more, upgrading to Lumo Plus unlocks the full suite of tools without sacrificing control.

With Lumo, AI finally works for you, not against your privacy.
