Whether you’re diving into machine learning, quantum computing, or macroeconomic trends, Persimmon makes research accessible, engaging, and available at your fingertips. Why Persimmon? The sheer volume of scientific research published today is staggering. Thousands of papers flood leading preprint servers like arXiv and SocArXiv each week, making it nearly impossible to stay informed without specialized knowledge. At the same time, scientific literacy is declining, with many people feeling disconnected from the innovations shaping our future. Persimmon tackles these challenges head-on by simplifying the process of exploring, understanding, and saving research papers – no PhD required! Key Features: - Customizable AI Summaries: Choose your preferred OpenAI-compatible language model (LLM) to generate summaries. Control costs and model preferences with your own API configurations. - Switch Between Providers: Seamlessly toggle between multiple LLM providers (e.g., OpenAI, Mistral, DeepSeek, Claude, custom models) using secure, on-device saved settings. - Tailored to Your Level: Set your expertise level (beginner, intermediate, or expert) for each topic to receive summaries that match your understanding. - arXiv & SocArXiv Search Made Easy: Find papers instantly with full-text search across arXiv and SocArXiv. Filter by categories to discover what interests you. - Offline Access: Save your favorite papers to read without an internet connection. - Daily Updates: Never miss a breakthrough! Get automatic notifications for the latest arXiv and SocArXiv papers in your chosen fields. - Privacy First: Persimmon respects your privacy.

Use Persimmon as a no-frills preprint browser. How It Works: 1. Set Your Interests: Select arXiv/SocArXiv categories or topics that fascinate you. 2. Choose Your AI Model: Configure your preferred LLM and expertise level to personalize summaries. 3. Explore & Save: Dive into abstracts, search papers, or save key findings for offline access. 4. Stay Informed: Get daily notifications to keep up with the latest advancements in your field. Privacy & Control: We believe knowledge should be private and empowering.
