Search Your Liked Videos on YouTube with This Tool
This tool uses OAuth to do its job, so you won't have to ask for credentials when it's running, making it simple to use and user friendly.
The search is based on channels, so you can query the videos of a particular channel or a collection of channels that are in your account. It can also be extended to include additional information such as comments or statistics, but it's limited to that search field. It also allows you to see the number of likes on a video and other related information.
