Popt Founder Gregorio Zanon on Redefining Mobile Note-Taking
Gregorio Zanon, founder of Popt, is pioneering a new approach to mobile notes. Popt, a mobile application, focuses on seamlessly connecting ideas, contacts, places, and time, all while prioritizing user privacy. This interview delves into the core principles behind Popt, its unique features, and its vision for the future of personal knowledge management.
Key Takeaways:
- Popt offers on-device processing for notes, ensuring maximum privacy and security.
- The app automatically recognizes and links people, places, and dates as you type.
- It aims to provide the depth of networked note-taking on mobile without compromising speed or simplicity.
- Popt allows for flexible note-taking, catering to various user workflows without enforcing rigid structures.
The Genesis of Popt: Addressing Mobile Note-Taking Gaps
Zanon identified a critical gap in the mobile note-taking space. Unlike desktop applications designed for deep work and knowledge organization, mobile note-taking often requires capturing fleeting thoughts on the go. Popt aims to bridge this gap by leveraging smartphone power for enhanced utility without the complexity.
The app distinguishes itself by turning plain text into interconnected data. Instead of relying on manual tags or cloud-based AI like ChatGPT, Popt uses an on-device text analysis pipeline. This ensures that user data remains private and secure, a core tenet of the app’s philosophy, influenced by Swiss privacy culture.
Designing for Intuition: “Note taking should work the way your mind works.”
Popt’s design philosophy centers on adaptability. Users can employ it as a simple scrapbook for quick lists or engage with its more advanced features like page creation and stickers. The app supports diverse workflows, allowing users to accept tagging suggestions or ignore them, and offers flexible reminder settings.
The core functionality involves automatically recognizing entities such as people, places, and dates within notes. For instance, typing “Lunch with Flavia at Mam from Hanoi Dec 11 1pm” can automatically tag Flavia as a contact, the restaurant, and the date, turning a simple note into an organized entry with potential reminders and links.

This interconnectedness allows users to easily navigate their notes. A note about a Paris trip, for example, can link to restaurant details, movie recommendations (integrated with The Movie Database), and contacts, with all relevant information accessible directly from the note.
Privacy and Data Ownership: A Swiss Approach
Popt’s commitment to privacy is unwavering. All processing occurs on-device, meaning notes never leave the user’s phone. When external services are integrated, like maps or movie databases, Popt uses clearly labeled search boxes to ensure users are aware that their input is no longer entirely private.
Data ownership is also paramount. Users can export their notes in bulk as plain text files, with compatibility for applications like Obsidian, ensuring data portability and freedom from vendor lock-in.
Real-World Use Cases and Future Development
Zanon shared personal use cases, including managing to-dos, planning trips, and even documenting Popt bugs within Popt itself. A notable example involved creating a shared page for a father-in-law, detailing a daily schedule for children’s activities, including directions and contact information.
Looking ahead, Popt plans to introduce more refined suggestions, additional tag types (books, games, music), and enhanced sharing options across more platforms. The team emphasizes user feedback in prioritizing future features.
Editor’s Take: Popt’s Bold Stance on Privacy and Usability
In a digital landscape increasingly dominated by data harvesting and cloud-centric services, Popt’s unwavering commitment to on-device processing and user privacy is not just refreshing—it’s revolutionary. Many productivity apps promise intuitive interfaces, but Popt delivers a genuinely flexible system that adapts to the user, not the other way around. The automatic entity recognition, especially for mobile contexts, moves beyond simple note-taking into a true personal knowledge management tool that feels both powerful and deeply private. This approach sets a new benchmark for what we should expect from our productivity software.
