I created this project some years back and the project just reached v1.1.0. I know most people have jellyfin servers and all set up, but if you have just a local folder of all your series saved up, you can use this to remember what you were watching.
All feedback is welcome. You can also contribute to the project
This looks promising. I keep some media on an external, encrypted ssd when I travel and just been relying on making a note of the episode and using haruna’s playback time feature.
