YouTube Monetization Checker by TubeLab is a Chrome extension that allows users to verify the monetization status of any YouTube channel, video, or short. It is the only extension that specifically supports shorts and channels dedicated solely to shorts. The tool provides detailed information on whether the content or channel is monetized through advertisements or sponsored videos.

This extension works by thoroughly examining the channel or video for indicators of monetization, such as custom ads, a sufficient number of subscribers, and sponsored content. Users should note that while the tool aims for accuracy, it may require occasional page refreshes due to layout changes in YouTube's user interface.
