I'm currently developing a new documentation tool called Scribe that is focused on teams. In my previous software role I found our team wiki (Confluence) to be a black hole. We had little to no visibility into how others interacted with our content, search did nothing for helping you find unknown unknowns and acting on outdated documentation became a common occurrence.
If this resonates with you have a look at the article I wrote on Medium that shows off a bit of what Scribe will be able to do :) If you like the cut of Scribes jib than be sure to sign up for beta access!
