I haven't heard of Shoko. How is it different from metadata grabbers like AniDB and AniList? The website makes it seem like it just uses AniDB to tag your episodes and series.
It organizes and renames files and also syncs your watch statuses for shows. Basically it works as a complete library management tool. It also checks the file hashes for anime against AniDB, so it's more reliable at getting the metadata right.
Mainly:
Playback Reporting - I love pretty graphs and it also helped me straighten my trakt feed from duplicates.
AppleMusic/CoverArt Archive/MusicBrainz - Music Metadata
Trakt - Playback Tracking
Spotify Import - Import Playlist from Spotify
Current disabled: YT metadata downloader. I run jellyfin in a container and would need to redo the image with yt-dlp or somehow pass the locally installed dlp package. Neither I am particularly interested in so I disabled it until I decide to refresh my metadata.
Subtitles are handled usually manually with bazarr (as an import but sometimes also a search tool)
Everything else is done with *arr.
