[Notion](https://www.notion.so/wikis). There are A LOT of videos on Youtube about it. I chose the following video to give you a quick taste: [How I Use Notion: The Best Productivity Tool I've Found](https://www.youtube.com/watch?v=536Q_kIImWk)

[Trello](https://trello.com/), not a wiki, is cross platform.

I use zim wiki to keep notes about projects I do. I find the wiki structure very very helpful. Sadly I am often not at home when I need to make notes, leaving me to make a note on my phone and then transcribing it when I get home. 

Does anyone know of a zim wiki like program that is cross platform so i can use it both on my phone, tablet and home computer?
