ChatGPT, Google Gemini, Microsoft Copilot, Grok… that’s just scratching the tip of the iceberg. There are now so many AI chatbot services out there, most of them run by American tech giants, and most of them are monitoring our conversations, collecting our inputs, and possibly even sharing that data with others.
Is there an alternative for the small remnant of society that still cares about privacy and personal data? Yes! That alternative is called Proton Lumo, which we first learned about back in July.
Proton is a Swiss company that’s best known for Proton Mail, the encrypted email service that started back in 2014. Since then, Proton has expanded its portfolio with all kinds of other privacy-focused alternatives to mainstream apps, including Proton VPN, Proton Drive, Proton Calendar, and Proton Wallet.
Proton Lumo is the latest addition to the company’s arsenal, an AI that runs on servers in Europe and incorporates models from companies such as Mistral and Nvidia.

Like its competitors, Lumo can answer questions, summarize documents, and generate text. But the difference is that everything you do is private and no one else can access your history. The drawback to Lumo is that it’s more limited than its competitors, which comes with the no-tracking and privacy-centric territory. It also can’t create images or videos.
You can try Lumo for free without registering, but you can unlock additional features by logging in. You can also lift the usage limits with a Lumo Plus subscription for $12.99/month.
