I use Workflowy (https://workflowy.com/ https://workflowy.com/) for everything: note-taking, planning and even project management (see https://medium.com/no-label-inc/4e911278c902 https://medium.com/no-label-inc/4e911278c902). I always have it open on my desktop and with their mobile app I'm always in sync. Workflowy is an excellent app and it keeps my thoughts organised. For longer documents that don't fit in the bullet-organized workflow of Workflowy I use Markdown.
