Great question, we are using similar tools!

Slack is where our conversations live, but trying to keep more persistent and organized information there didn't work well for us.

We are also using Google Drive, but mainly for file management and working on documents which require full control over the styling and layout (e.g. legal documents that need to be printed). For more dynamic content and ad-hoc information, it feels too heavy to us.

Github (Wiki) is great for static text content and fine grained change tracking. Besides that, it's rather hard to use for non-developers as you pointed out.

We use Nuclino for collaborating on rich content that is more persistent than conversations in Slack and which does not need the overhead of a system like Google Drive. We haven't used Quip too much, but feel that it's rather similar to Google Drive with the files, folders, documents, spreadsheets and the likes.

To keep the core experience lightweight in the long term, we plan on supporting integrations that extend Nuclino.
