About SidePen - Web Page Annotation
SidePen - Intuitive Annotation & Feedback Tool for Web Pages
SidePen is a productivity and creative feedback tool designed to help you draw, annotate, and leave notes directly on any webpage. Whether you are providing design feedback, taking research notes, or highlighting key information during a presentation, SidePen allows you to mark up the web in real-time.
【Key Features】
・Versatile Drawing Suite: Includes a "Pen" for freehand sketching, an "Arrow" tool for precise highlighting, and an "Eraser" to quickly clean up your annotations.
・Draggable Sticky Notes: Simply click anywhere on the page to create a text note; these notes can be edited and moved freely to provide detailed feedback.
・Instant Screenshot Capture: Save your annotated view as a timestamped PNG file with a single click, capturing all your drawings and notes exactly as they appear.
・Sleek Floating Toolbar: A vertical, non-intrusive UI panel stays on the side of your browser, keeping your essential tools accessible across different tabs.
・Smart Interaction Management: Automatically toggles between "Edit" and "Draw" modes to ensure smooth annotation without interfering with the underlying website's functionality.
【How to Use】
1. Click the SidePen extension icon to toggle the side toolbar on or off.
2. Select a tool from the toolbar, such as the Pen, Arrow, or Text tool.
3. Draw directly on the page or click to place a Sticky Note for text-based comments.
4. Use the Save button to instantly download a screenshot of your annotations.
5. Switch back to the Pointer mode whenever you need to interact with the original webpage links or buttons.
