ShareX

ShareX is a free and open-source desktop program for Windows that allows users to capture or record any area of their screen. It provides various capture methods, image editing tools, and options to upload captured content to a wide range of supported destinations.

ShareX is primarily a screenshot tool with screen recording capabilities. While it offers screen recording and some basic editing tools, it lacks the advanced, automated editing features like automatic cursor tracking, dynamic zoom, and automatic subtitle generation that are 'must-have' for FocuSee. It does support multi-source recording (screen and audio), basic editing, platform integrations for sharing, and keyboard shortcuts.
