PdfScratch: Your Interactive Whiteboard for Web Pages and PDFs

Turn any website and local PDF into your personal, limitless notepad. With PdfScratch, you add a smart overlay to your browser that allows you to structure information right where you read it—without constantly switching between tabs or external programs.
Whether you are working through complex math scripts, analyzing 1000-page reference manuals for microcontrollers, or visually organizing your research: PdfScratch combines a PDF reader, a snipping tool, and a mind map into a single, high-performance browser extension.

Key Features:
Integrated Snipping Tool (📸 Snip): Cut out exactly the section of the website or PDF you need with a single click. The snippet instantly drops onto your whiteboard as a movable image.
Full-Featured Drawing Tool (🖌️ Draw & 📝 Text): Create handwritten notes, draw connections, or add typed text blocks. Pen color and thickness can be adjusted directly in the overlay.
Multi-Map Project Management: Work on multiple topics simultaneously. Create as many whiteboards as you need, name them, and switch seamlessly between them using the dropdown menu. Each map remembers its own state.
Smart Object Management (🖐️ Select & 🧽 Erase): Every stroke, text, and image is treated as an independent object. Move elements around later, use the eraser for quick corrections, or simply delete selected objects with the Delete key.
Seamless Zoom: Hold down the Ctrl (or Cmd) key and scroll with your mouse to zoom smoothly into your scripts and notes, or to get a bird's-eye view of your entire mind map.
Customizable Workspace (⚙️ Options): Choose the background that best fits your workflow: clean blank white, a subtle dot grid, or classic lined paper.
Floating Action Button: Minimize the board to continue reading undisturbed. A subtle, floating widget at the edge of the screen lets you pop your whiteboard back open anytime with just one click.

Perfect For:
Distance and On-Campus Students: Open lecture notes in the browser, snip important formulas or diagrams, and sketch out your own solutions right next to them.
Developers & Engineers: Gather relevant pinouts, datasheet excerpts, and code snippets from various sources onto one board without losing context.
Knowledge Workers & Creatives: Build visual research, mood boards, and brainstorms directly on top of your source of inspiration.
