Technically speaking this is Matrix, if you create a GUI that looks like an e-mail client instead of an instant messenger.

Sure, but that would be the case if it was designed like that from the ground up, but BookWyrm’s developer didn’t and it’s understandable, so now you either fork it and make it like that or fork it and make it work specifically for whatever you want to keep track of.

I asked them if it’s possible and they said yes if you modify the back end, but I don’t think they have time to maintain two projects like this. :/

If you get yourself a Python developer which isn’t that crazy you could do it though.

bookwyrm, and no it does not

It’s the same concept, Letterboxd is not the only one doing it, there’s also Film Affinity (which IMO is better since it doesn’t make this stupid distinction between films, TV shows, shorts, and so on, which Letterbox does), but yeah.

No, there isn’t it’s probably one of the things I need the most. There’s BookWyrm which is a replace for something very similar but for books, and there’s also another website for anime manga which is called Kitsu. I would love to grab the source code of one of these and modify the variables to adapt it for cinema, but I am too stupid to do that
