Papyrs

Papyrs makes it easy for companies and teams to build an internal site to share information and work together.
It's a new take on knowledge bases, team wikis and intranet sites. Build an internal site with whatever you need to work on: notes, files, checklists, videos, forms/databases, calendars, and more.
It's all drag&drop (or Markdown if that's your thing)

Papyrs' clients include companies large and small who need a central place online to collaborate and share information with co-workers or clients
