The default trigger is double-tap Command, and users can also record their own global shortcut. After capture, screenshots open in a lightweight floating editor where users can annotate, crop, beautify, pin, copy, save, or upload without moving through a heavy project-management style interface. capcap is especially useful for people who write documentation, file issues, give design feedback, record ideas, and need polished screenshots every day. It focuses on quick capture and clear handoff rather than building a media library or collaboration workspace. ## Privacy and business model - capcap is local-first. - capcap has no telemetry. - capcap has no subscription. - Screenshot history, color history, and image-host credentials stay on the user's Mac. - Image-host keys are stored locally. ## Core workflow 1.
