Proton—the folks who brought us the ultra-secure Proton Mail—just unleashed something pretty awesome: a new AI assistant called Lumo. And trust me, this isn’t your average chatbot. It’s a privacy-first powerhouse that’s here to shake things up in a world where Big Tech often treats your data like it’s their personal piggy bank.

If you’ve ever used Proton Mail, you know Proton is all about keeping your stuff private. So, it’s no shocker that their new AI assistant, Lumo, follows the same vibe. Proton’s CEO, Andy Yen, isn’t pulling punches—he’s framing Lumo as a direct challenge to what he calls the “surveillance capitalism” of Big Tech. That’s a fancy way of saying companies like Google and others often profit by harvesting your data. Proton? They’re flipping the script, promising “AI that puts people ahead of profits.” Bold words, but Proton’s got the cred to back it up.

Based in Switzerland—yep, the land of strict privacy laws and neutrality—Proton’s got a solid foundation for this privacy-first mission. Lumo isn’t just a tool; it’s a statement. But what can it actually do? Let’s break it down.

Lumo’s no slouch when it comes to features. It’s got the chops to handle everyday tasks with ease:

• Summarizing documents: Got a monster PDF you don’t want to slog through? Lumo can give you the CliffsNotes version.
• Writing code: Need a quick Python script or some HTML? Lumo’s got you covered.
• Composing emails: Writer’s block hitting hard? Let Lumo draft that message for you.

But here’s where it gets juicy: all this happens without your data leaving your device. That’s right—everything stays local, locked down with some serious security magic. Proton calls it “zero-access” encryption, which means you get a unique key to your data. Without that key, it’s all gibberish—even to Proton. No advertisers, no governments, no AI training datasets. Just you and your info, safe and sound.

Upload a file for Lumo to chew on? Once it’s done, it forgets everything. Link something from Proton Drive? It stays end-to-end encrypted the whole time. For anyone who’s ever worried about their data being scooped up and sold, this is a game-changer.

Let’s talk about what sets Lumo apart: its privacy game is next-level. Here’s the rundown:

• Zero-access encryption: Only you hold the key. Proton can’t see your data, period.
• Local storage: No cloud shenanigans—your data lives on your device.
• File amnesia: Lumo analyzes your uploads and then wipes its memory clean.
• Encrypted integrations: Pair it with Proton Drive, and your files stay locked tight.

Oh, and that web search thing? It’s off by default to keep your privacy intact. If you flip it on, Lumo taps into “privacy-friendly” search engines—no Google or Bing tracking your every move. It’s little touches like this that show Proton’s not messing around.

Under the hood, Lumo’s running on some slick open-source large language models, hosted on Proton’s servers in Europe (where privacy laws are no joke). We’re talking Mistral’s Nemo, Mistral Small 3, NVIDIA’s OpenHands 32B, and the Allen Institute for AI’s OLMO 2 32B. These aren’t household names like ChatGPT, but they’re heavy hitters in their own right.

What’s neat is how Lumo plays matchmaker with your questions. Ask something code-related, and it hands the job to OpenHands, a coding whiz. Need a summary? Another model steps up. It’s like having a squad of specialists, all working for you—transparently, thanks to that open-source vibe.

Ready to try Lumo? You can hit it up on its website (lumo.proton.me) or grab the iOS and Android apps. Access comes in three flavors:

• No account: Dip your toes in with a few questions a week. No chat history, though—use it and lose it.
• Free account: Get encrypted chat history, small file uploads, and a handful of saved favorites.
• Lumo Plus ($12.99/month): The full monty—unlimited chats, longer history, unlimited favorites, and big file uploads. For power users, this is the sweet spot.

It’s a tiered setup that lets you test the waters or go all-in, depending on your needs.

So, how does Lumo stack up against the likes of ChatGPT or Google’s Gemini? Simple: it’s all about the data. ChatGPT, built by OpenAI, uses your inputs to fine-tune its models—great for them, not so great for your privacy. Google’s Gemini? Well, Google’s an ad giant, so you can bet your data’s getting a good look-over. Both are powerful, sure, but they thrive on collecting what you give them.

Lumo’s the oddball here. It doesn’t care about improving itself with your data—it’s built to serve you, not some corporate bottom line. Plus, with Proton’s Swiss roots and open-source models, there’s a level of trust and transparency you just don’t get with the proprietary giants.

Look, AI assistants are everywhere these days, but most come with a catch: your privacy takes a hit. Lumo’s different. It’s Proton saying, “You can have your cake and eat it too—powerful AI and peace of mind.” In a world where data breaches and tracking scandals are practically daily news, that’s huge.

Lumo’s not here to be the flashiest AI on the block—it’s here to be the most trustworthy. Whether you’re a coder, a busy professional, or just someone who hates the idea of their data being up for grabs, Lumo’s got something for you. It’s practical, it’s private, and it’s proof that AI doesn’t have to come at the cost of your personal info.
