Storybook Extractor is a Chrome extension designed to automate the conversion of Google Gemini storybooks into professional, printable PDF documents.
It intelligently extracts high-resolution imagery and text, removes watermarks automatically using reverse-alpha blending, and reformats the content into a clean, paginated layout suitable for e-books or physical printing (KDP).
- AI Watermark Removal: Automatically detects and removes Gemini watermarks from illustrations.
- Print-Ready PDFs: Generates standard Letter-sized PDFs with proper margins.
- Smart Formatting: Automatically builds a Cover Page, Title Page, and alternating Illustration/Text pages.
- Client-Side Only: No servers and no uploads. All processing happens locally in the browser for privacy.
- Typography: Embeds the Poppins font family for a modern reading experience.
