CopySage - Clipboard Inspector Ever wondered why your paste operations don't work as expected? CopySage reveals exactly what's in your clipboard. Born from frustration with paste formatting issues, CopySage is a diagnostic tool that provides detailed insights into your device's pasteboard (clipboard) content. What started as a quick debugging solution is now a powerful analyzer that can save you hours of troubleshooting. THE STORY I was struggling to paste text with links into email clients and messaging apps with proper formatting. Despite countless attempts, nothing workedβ€”yet other apps pasted similar content perfectly. After building a quick diagnostic tool to inspect what successful apps were putting in the pasteboard, I discovered I was missing a critical type. Ten minutes later, everything pasted beautifully. If this app saves someone else days of aggravation, it will have been worth it. WHAT IT ANALYZES Text - Content with encoding details Images - Dimensions and format information URLs - Web links and deep links Colors - RGB and HSB values Dates & Times - Temporal data Numbers - Numeric values Files - Document information Raw Data - Binary content with hex viewer PERFECT FOR Developers debugging pasteboard interactions Discovering what format apps use when copying content Troubleshooting failed paste operations Inspecting rich content before pasting Understanding how the clipboard works HOW IT WORKS Copy any content from any app on your device Open CopySage Tap the paste button (you'll be asked to allow clipboard access each time) Browse the detected pasteboard items Tap any item for detailed information and preview The app handles multiple format representations of the same content, as apps often place several versions in the pasteboard for compatibility. YOUR PRIVACY MATTERS CopySage only reads your pasteboard when you tap the paste button. It does not store, transmit, or track any clipboard content. All analysis happens locally on your device. Simple. Local. Essential for anyone working with clipboard data.
