• Fast Rendering Engine: Instant page loading without lag, even on 200MB+ documents.
• Annotation Capabilities: Highlighting, sticky notes, text insertion, and freehand drawing.
• Search & OCR Support: Rapid full-text search across all chapters.
• Dark / Night Mode: Inverted color palettes to reduce eye strain during late-night study sessions.
• Cross-Platform Cloud Sync: Bookmarks and reading progress synced between laptop and phone.
