A web app to build and tidy your YouTube playlists: search and filter your videos, save the results as a new playlist, and clear duplicate, private and removed videos.

What to expect from an ideal product
- TidyList scans your YouTube playlists and flags every private and removed video so you can delete them in one clean sweep instead of hunting them down manually.
- Broken videos left in playlists hurt watch time and viewer experience, TidyList lets you remove them before they become a problem.
- No browser extension needed, TidyList works directly in your browser as a web app, so there is nothing to install or update.
- Beyond cleanup, you can search and filter your existing videos, then save the results as a brand new playlist without touching YouTube Studio.
- If you manage large playlists with hundreds of videos, TidyList removes duplicate entries and dead links in the same workflow, saving you from doing it row by row.
