Proton has rolled out version 1.2 of Lumo, its privacy-centric AI assistant, delivering two frequently requested enhancements—dark mode support and customizable writing styles for conversations. The update reinforces Proton's commitment to user privacy while expanding functionality for both casual and professional workflows.
Visual Consistency Across the Ecosystem 🎨 Users can now toggle between light and dark themes, bringing Lumo's interface in line with Proton's broader product suite. This visual alignment creates a cohesive experience across Proton Mail, Drive, and other services while reducing eye strain during extended usage sessions.
Personalized Communication ✍️ The addition of custom writing styles allows users to tailor Lumo's conversational tone and output format to match specific needs. Whether drafting formal business communications or casual creative content, users gain precise control over how the AI assistant responds and composes text.
Enhanced Document Context 📄 Proton Drive integration remains a core feature, enabling users to attach or remove documents and PDFs from Lumo's working memory. This capability provides the assistant with relevant context, improving response accuracy for document-based queries and professional tasks requiring reference materials.
Building on Solid Foundations Version 1.2 extends the reasoning and knowledge improvements introduced in the previous 1.1 release, delivering more sophisticated analysis capabilities for both everyday inquiries and specialized professional applications. The cumulative enhancements position Lumo as an increasingly capable assistant across diverse use cases.
Privacy Without Compromise 🔒 All personalization features operate under Proton's zero-access encryption framework, ensuring complete privacy protection. The platform stores no chat logs and uses no conversation data for AI model training, maintaining Proton's foundational commitment to user privacy and data sovereignty.
Flexible Subscription Model The new features arrive free for all Lumo users, but Proton now offers Lumo Plus as both a standalone subscription and an optional add-on. This tier unlocks faster response times, expanded working memory capacity, and unlimited chat usage without requiring bundling with existing Unlimited, Family, or Duo plans. The standalone approach provides flexibility for users seeking enhanced AI capabilities without comprehensive Proton ecosystem subscriptions.
This release demonstrates Proton's strategy of combining robust privacy protections with practical feature development, addressing user feedback while maintaining the security principles that define the brand.
