I feel like nextcloud replacement is out of scope ?

I mostly felt like Timelize was about being *behind* data-generating applications and showing and cross-referencing their data when reading the website.

I think the way is to do some sort of nextcloud extension that puts data into Timeline.

I also saw it tracks "documents" on the website but I didn't try it yet, and I would hope it can use external document sources that are already processing documents like paperless for example (which I am already using and liking)
