WebSequenceDiagrams has been my go to for years, and I'd be basically brainstorming straight in it in lieu of pen and paper. I laughed the day one of my colleague was explaining his issue on the whiteboard and he was writing it "A->B: some action" style instead of the actual box and arrow sequence, it just became part of our culture I think.
I had to move on when I couldn't get it approved at the place I worked, and nowadays PlantUML tools have become "good enough" (still wish Notion had PlantUML support instead of mermaid...), but I'm incredible thankful your service is still up and running.
