Jing is a visual communication tool that allows users to easily capture and share screenshots and videos from their computer screen. It has both free and paid Pro versions. The free version allows users to record up to 5 minutes of screencasts and annotate screenshots. The Pro version offers additional features like removing the Jing branding and uploading videos directly to YouTube. Jing makes it simple to demonstrate tasks, provide feedback, and explain concepts visually. Users can save, email, or upload their Jing captures to sites like Screencast.com to easily share them with others.
