HoloTagger

Web application for tagging and downloading karaoke covers sung by vtubers.
The application consists of an API and simple web interface.

It works by giving a link to a youtube video, after which the video is downloaded and converted into a mp3 file.

The app also adds metadata to the song (e.g. thumbnail, artist, etc).
The artist tag is generated by matching channel IDs from vdb or fuzzy searching the video title (romaiji is also taken into account).

Development

poetry is used for package management. To setup the project for development, simply run:

$ poetry install
