What's New in Persimmon

0.4.0

April 1, 2026

Release 0.4.0 - "Help, I'm Syncing!" Welcome! In this version, we wanted to focus on enabling you to access Persimmon from all the devices you may want to. To wit, here are all the new additions in this release: 1. User accounts and sync: If you use Persimmon from multiple devices, this one is for you. Now, you can make an account with Persimmon Cloud and sync interests across devices automatically! If this isn't for you, Persimmon is still completely functional without an account on each standalone device - we won't ever love you any less. 2. Articles by followed authors: A new tabbed view displays articles from the authors you follow. We're not fans of Instagram but this feed-structure is genuinely pretty useful. 3. "Feeds" page: A new interface for configuring sources (arXiv, socArXiv) and their respective subjects can be found in Settings. 4. Native PDF/link viewing: View the contents of PDFs or webpages from arXiv/SocArXiv inside Persimmon by default. This can be changed in Settings > Preferences to route to your default browser instead. 5. API status indicator: A new panel can be found in Settings that shows information (status, latency metrics, etc.) for all the APIs that Persimmon can call, making troubleshooting connection issues easier. Other Improvements - Streamlined onboarding flow for new users. - Fixed a critical bug leading to incorrect author/article search results from arXiv. - Fixed a bug showing no articles for authors from SocArXiv. - Narrowed the OSF API to show only authors from SocArXiv and no other sources. - Fixed a bug that resulted in incorrect removal of some authors common to arXiv and SocArXiv. - Fixed a bug where the subject tags would randomly shuffle positions inside article tiles. We're hard at work on a native macOS port of Persimmon (coming very soon) and more exciting features on the Persimmon Cloud side that make analyzing research papers using LLMs even more intuitive and expansive in scope. See you in the next update, enjoy!
