I have been using this site. Not sure how accurate it always is. Source: about 1 year ago

I recommend googling lots of "best of" lists..like "best thrillers", "best movies of the 90s", etc. Also the site https://bestsimilar.com is really helpful cause you can enter any movie and it'll give you a list of similar ones. Source: over 1 year ago

I have found sites like https://bestsimilar.com/ where you give a movie as input and get some movies like the one you plugged in. My problem is that I don't always know what I like to watch. Also, I found an AI that can recommend movies based on your letterbox watched films but I think it just recommends top movies. Source: almost 2 years ago

That said, I did a little digging over at Awesome Self-hosted, and came across one entry that might be promising: Inventaire. Source: about 2 years ago

Try to take a look at https://inventaire.io/ (source-code at https://github.com/inventaire/inventaire) a neat piece of software currently developed (and with the goal to make it self-hostable if you want and federated) book management, it may come in handy. Source: almost 3 years ago
