🎯 What's New

This release adds intelligent query routing and accurate page citations!

Intelligent Query Detection

SmartReader now automatically detects what you're asking and adjusts its strategy:

• 📋 Summary queries → Uses first 3 pages
  • "Summarize", "What is this book about?", "TLDR", "Overview"
• 📄 Page-specific queries → Direct page access
  • "What is on page 5?", "Show me page 12"

  • "Summarize chapter 3", "What's in chapter 1?"
• 🔍 Specific questions → Semantic search
  • "How does memory work?", "What are the key findings?"

Accurate Page Citations

• ✅ Validates citations - Warns if model cites non-existent pages
• ✅ Strict prompts - Explicitly tells model which pages to cite
• ✅ Lower temperature (0.2) - Reduces hallucination
• ✅ Post-processing - Checks and validates all page numbers

Larger Context Window

• Context increased from 4000 → 8000 characters
• Summaries now include content from all first 3 pages
