On my own personal project where I have a team of 8 I tried Gitbook but when I lost a bunch of stuff do with git pull that override my local changes I really disliked Gitbook.
I convinced my work to get on Confluence so we at least have a knowledge base. I find Confluence like all Atlassian products clunky, slow and cumbersome to navigate.
I really liked Backpack, however its dated and structuralized for an older workflow.
I look at Slite and think, does it handle code blocks well? Is it navigation easy and feels fast? How clunky is the rich text editor?
I personally don't like the look, the open source outline looks more professional. I would have borrow design elements from Discord than Slack.
To me this is a gimmick of piggybacking on the familiarity of slack channels to take something that has already existed (collaborative note and note-like apps). An old tool for a new generation.
Since I've built my open-source HTML5 game in Electron I feel I could whip up my own note-taking app because my feeling is I'm not going to be sold on either Outline or Slite.
I went to connect with my Google Account As soon as Slite asked to view my Contacts, I stopped. Its like asking to see someone's facebook on a first date. No Thank you.
So I go and check Outline, since its open-source but you have to have a slack account and create a Slack App, No Thank you.
I guess I should build my own.
