Since you asked for feedback... get a native speaker to review your copy. "leverage on" - you don't need the "on" (this is in 2 places). "Notes are information that aimed at becoming knowledge" - doesn't make sense, perhaps say "aims" instead? hierarchizations - just say hierarchies.
Well, you asked : P
Of course it's collaborative (like a wiki) and everyone in the team can add/edit just by typing in the dok (like in asana), no edit button or whatever. Oh and behind, it's HTML5/JS with Meteor.
Feedback will be greatly appreciated.
