 # Paper Index - AI Paper Evaluation System
 
-A comprehensive system for evaluating AI research papers using advanced language models.
+A comprehensive system for evaluating AI research papers using advanced language models with asynchronous processing and concurrent evaluation capabilities.
 
 ## Features
 
 - **Daily Paper Crawling**: Automatically fetches papers from Hugging Face daily
 - **AI Evaluation**: Uses Claude Sonnet to evaluate papers across multiple dimensions
+- **Concurrent Processing**: True asynchronous evaluation with multiple papers processed simultaneously
+- **Re-evaluation**: Ability to re-run evaluations for papers with updated results
+- **Batch Evaluation**: "Evaluate All" feature to process multiple papers at once
 - **Interactive Dashboard**: Beautiful web interface for browsing and evaluating papers
-- **Database Storage**: Persistent storage of papers and evaluations
+- **Asynchronous Database**: High-performance SQLite with WAL mode for concurrent operations
 - **Smart Navigation**: Intelligent date navigation with fallback mechanisms
+- **Real-time Status Updates**: Live progress tracking and notifications
