Try without an API key
Browse and search removable test samples from five public channels and up to 50 videos with offline comment examples. Images and video playback need internet access.
Live data and comments
Live search, channel imports, refresh and comments need a valid YouTube Data API key. Sign in with Google and grant the requested permission to post and manage comments. Writes are initiated by you; failed posts are not automatically retried.
Backups and help
Save a library backup before updates and avoid uninstalling when upgrading. Keys are not included in database exports. For help, include your app version, device, OS and steps to reproduce, but never send credentials or a full database. To report a real comment, choose Report comment on YouTube and complete the report in the YouTube comment menu. Manage local filtering, hidden comments and author blocks in Settings → Comment safety.
