Spade: Draw on and Annotate the Web & PDFs
Spade is a free Chrome add-on developed by The Spade Team that allows users to draw, annotate, and save their ideas and thoughts directly on webpages and PDFs. With a powerful toolbar, users can easily mark important information using a pen, highlighter, and text box. The annotations can be saved to the cloud and organized into folders on the Spade website. Additionally, users can download annotated web pages as PDFs and share them with others.
Spade offers a range of tools including a pen with shape detection, a highlighter, text boxes, and an edit tool for moving and resizing annotations. The add-on also supports keyboard shortcuts for quick tool switching, undo, and redo. Users can customize their annotations with different colors, font sizes, and fonts.
The mission of Spade is to transform web browsing into an interactive experience. By enabling users to capture, record, and share their ideas across the web, Spade aims to deliver a personalized web experience. Users are encouraged to provide feedback to the developer via email at
