I use Dynalist for quite extensive note taking and writing. Bullet points/lists is where a lot of my thinking starts.
DL is in many cases my starting point, quickly outlining what I think in a Notepad document.
I’ve been using Evernote since its start (before it became a cloud synced program) and have a lot of personal notes in it. For that reason I continue to add diary/log entries to Evernote. When I feel the need to journal something out, it goes into Evernote as well.
I use TheBrain for interconnected, visualized, associative knowledge and information.
Longer documents I prefer to write in Markdown so they remain accessible for as long as possible. Currently using Typora for that.
