Personally a big fan of Vimflowy, an open source self-hostable version of Workflowy with vim-like controls:

Dev is super pleasant as well :)

I use Dynalist which is also similar to workflowy.

Cool! Notion (https://notion.so) is also similar, I use it personally and at work and it's an awesome product.

Thank you! I didn’t know that! My app is similar to that one >< I need to make representatives function which distinguishes this from that!
