Lumo 1.2 is here, and it’s all about tailoring your experience to help you be more productive. Feedback from our community shows you want a private AI assistant(ventana nueva) that’s more customizable to your needs — whether that’s switching to dark mode or asking Lumo to respond with a consistent tone or style.

Following our major knowledge and reasoning improvements with Lumo 1.1, the new Lumo 1.2 delivers on two highly requested features:

  • Choose your favorite look for Lumo with dark mode
  • Customize your experience by setting your preferred writing style for Lumo

As always, your chats in Lumo remain completely confidential. Any personalization options you enable retain Lumo’s zero-access encryption, meaning Lumo never keeps any logs and your chat histories are only accessible to you.

Dark mode is here

Dark mode has been one of our community’s most highly anticipated updates for Lumo. Throughout the Proton ecosystem, you can customize the look of all of your apps, and now you can customize Lumo, too, with a light or dark theme.

Customize Lumo’s writing style

Lumo already lets you integrate Proton Drive so that it’s easy to add or remove documents and PDFs from Lumo’s working memory. That’s a powerful way to give Lumo more context for your chats and get better results.

To personalize Lumo further, you can now specify your preferred writing style, tell Lumo your name, and share any other instructions you’d like Lumo to keep top of mind. Getting the answers you need in the way you want them helps you work faster and more seamlessly.

Finding the perfect voice for Lumo makes it easier to find the words you’re looking for, whether you’re writing a casual email or a formal research proposal. The traits you choose for Lumo and the information you want Lumo to remember about you can help you create the ideal AI assistant that always speaks your language.

Crucially, adding personalization doesn’t compromise your privacy: Your chats are still fully confidential and they aren’t used to train Lumo’s models. Even while you’re teaching Lumo how to speak more like you, your conversations are still private and secured with zero-access encryption(ventana nueva).

Get more from Lumo with Lumo Plus

These updates are free to all Lumo users, but you can unlock more space for chat knowledge, get faster responses, and unlimited usage with Lumo Plus. Upgrade to Lumo Plus to unlock its full power and invest in the future of privacy-first AI.

Because Lumo is expensive to operate, we are making Lumo Plus available as a standalone product or an add-on rather than raising prices and adding it by default to existing Unlimited, Family, and Duo plans. At Proton, we give you the freedom to only use AI if you want to.

Building AI that doesn’t exploit you

You don’t need to give your data to Big Tech in order to access powerful AI tools. Lumo was built to give you the power of AI without forcing you to submit yourself to mass surveillance.

With a business model that doesn’t rely on selling your data, Lumo is the privacy-focused alternative that’s changing what you can expect from AI and helping you make the most of it. As always, let us know your thoughts and feedback on X(ventana nueva) and Reddit(ventana nueva).
