Persimmon: Research Simplified

Welcome to Persimmon, the ultimate AI-assisted research exploration tool for iOS! In a world where scientific breakthroughs are accelerating faster than ever but many struggle to keep pace, Persimmon bridges the gap between cutting-edge research and everyday understanding. Designed for researchers, scientists, students, and anyone with a passion for discovery, this app transforms complex arXiv paper abstracts into digestible, tailored insights using advanced language models. Whether you're diving into machine learning, physics, or quantum computing, Persimmon makes science accessible, engaging, and available at your fingertips.

Why Persimmon?
The sheer volume of scientific research published today is staggering. Thousands of papers flood arXiv 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 Search Made Easy: Find papers instantly with full-text search. Filter by categories like physics, math, CS, or biology to discover what interests you.
- Offline Access: Save your favorite submissions to read without an internet connection — perfect for on-the-go learning.
- Daily Updates: Never miss a breakthrough! Get automatic notifications for the latest arXiv papers in your chosen fields.
- Privacy First: Persimmon respects your privacy. There’s no data collection, tracking, analytics, or user accounts — browse and learn freely.
- Lightning-Fast Performance: Built entirely in SwiftUI with minimal dependencies, the app is snappy, intuitive, and optimized for iOS.
- AI-Optional: Prefer raw data? Use Persimmon as a no-frills arXiv browser. The choice is yours!

How It Works:
1. Set Your Interests: Select arXiv 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.

For Researchers & Learners:
Persimmon is more than a browser — it’s a knowledge companion. Whether you’re a student struggling to grasp a dense paper, a scientist tracking interdisciplinary trends, or a curious mind eager to learn, Persimmon adapts to your needs. The app’s AI breaks down jargon-heavy abstracts into plain, actionable insights, helping you focus on what matters: the ideas themselves.

Privacy & Control:
We believe knowledge should be private and empowering. Persimmon stores all configurations and preferences securely on your device, with no cloud syncing or data sharing. Your exploration stays yours.

Persimmon is completely free to use, with a setup time under 30 seconds. At best, it becomes your go-to tool for staying ahead of the science curve. At worst, you’ve got a sleek, private browser for arXiv. Either way, we’re excited to help you unlock the world of research.
