Popt Founder on Rethinking Mobile Notes for Privacy and Intuition
Gregorio Zanon, founder of Popt, is challenging the status quo of mobile note-taking. His app, Popt, focuses on seamlessly connecting ideas, contacts, places, and time, all while prioritizing user privacy through on-device processing. This approach aims to make mobile notes more dynamic and useful without compromising security.
Key Takeaways:
- Popt emphasizes capturing thoughts quickly on mobile, akin to a scrapbook.
- It turns plain text into an interconnected map by automatically tagging people, places, and dates.
- All processing happens on-device, ensuring maximum privacy and offline functionality.
- The app offers flexibility, allowing users to engage with its features as much or as little as they prefer.
The Mobile Note-Taking Gap Popt Fills
Zanon identifies a gap in current mobile note-taking apps: they often fail to accommodate the spontaneous nature of capturing ideas on the go. Popt aims to bridge this by allowing users to jot down thoughts without worrying about structure, while still leveraging the power of smartphones to enhance note utility.
Instead of traditional hashtags or manual linking, Popt uses on-device text analysis to suggest links to real-world entities like people, places, and dates. These tags transform simple notes into dynamic elements like reminders, contact cards, or map entries.
Privacy by Design: On-Device Processing
A cornerstone of Popt’s philosophy is user privacy. Zanon explains that relying on cloud-based AI like ChatGPT for note analysis would compromise user data and privacy. Popt’s solution is an on-device text analysis pipeline that runs entirely locally, ensuring that notes remain a secure, private space.
This commitment extends to data ownership. Users can export their notes as plain text files, with compatibility for popular apps like Obsidian, ensuring data portability and freedom from vendor lock-in.
An Interconnected Map of Your Life
Popt’s core functionality revolves around transforming plain text into an interconnected network. For instance, a note like “Lunch with Flavia at Mam from Hanoi Dec 11 1pm” can be automatically tagged, linking to Flavia’s contact, the restaurant, and the date. This note can then be easily found via the ‘Dates’ tab or updated with more details, such as a movie recommendation like ‘Arco’, which Popt can enrich with data from The Movie Database.

The app visualizes these connections through dedicated tabs for Places, Dates, and other recognized entities, allowing users to navigate their information spatially and temporally.
Editor’s Take: The Future of Personal Knowledge Management
Popt represents a significant step forward in personal knowledge management, particularly for mobile users. By prioritizing privacy and intuitive linking, Gregorio Zanon and his team are not just building another notes app; they’re crafting a tool that actively works with the user’s mind. The on-device processing is a crucial differentiator in an era of increasing data surveillance. While many apps are racing to integrate AI, Popt’s focus on human-designed, privacy-preserving systems feels both refreshing and essential. This approach could set a new standard for how we manage our digital lives.
What’s Next for Popt?
Popt is still in its early stages, but Zanon hints at future developments including more refined suggestions, additional tag types (books, games, music), enhanced sharing options, and broader platform support. The team encourages users to try Popt, which is available without sign-up or a paywall, and provide feedback to help shape its future.
