There are a ton of tools like Notion, Obsidian, Logseq, etc. that are all focused on primarily text/document first.
I've been spending a lot of time doing both design work and doing more creative/artistic fun stuff, but I also do a lot of reading and note taking and am hoping to find a tool that can bring all of this into one tool.
There are a lot of visual infinite canvas type tools like Miro, Milanote, Muse, etc. that are great for dumping images, doodling on the canvas, and organizing things however you want.
And there seem to be some tools somewhere in the middle, like Scrintal (terrible name lol) and Heptabase. There are some others, though they seem fairly anemic in terms of features and are more just another notion-like tool but you can put the notes on a canvas.
I guess the short of it is that I don't know exactly what I'm looking for and I'm hoping that some others here have found a nice solution for their own note taking/knowledge dumping which works in a visual way.
Edit, as that didn't really answer the question: no, I don't have any digital visual note taking app I prefer. I use a paper notebook for that, because handwriting and sketching is engaging and I find I remember better what I was thinking at the time.
When I need to collaborate I usually set up a Figjam board though.
But to keep a similar system between work and personal I used Obsidan + Excalidraw (inside obsidian). IMO it gives the best of both worlds.
