- Love Confluence for many reasons. You need to make sure you go in with a strategy for organizing your content, but I find adjusting mid-stream (especially in product design) is easiest with a platform like Confluence. If you are a JIRA shop, doing as much planning and documentation in Confluence before going to JIRA pays dividends.
Its a great tool for starters, For teams I do not recommend. there are lots of apps that do the same, even google docs is more intelligible when collaborating and working with. But we already have OneNote, Evernote, Word Online, with lots of features way ahead Paper.
Use Paper to manage technical stuff and my team, and love it. Just the right number of features, document crosslinking and image embedding fits my needs exactly, and works for quick notes or longer documents.
