My lawyers narrowly tailor the NDA to relevant topics. So pretty much no copy and pasting will work. Usually that is only a modification of the first or second paragraph from familiar NDAs but the stuff on the internet is overly broad.
You don't need a lawyer in order to adopt this concept. But if you are just dealing with one of clients and want them to sign an NDA, or you are asked to sign theirs, consider narrowing it down instead of having it cover everything under the sun.
I don't know what you mean by "narrowly taylor", but if you mean "fill in the purpose for which information's being shared", read Waypoint. The first page has a blank for that. Along with governing law, forum for disputes, and term.
Waypoint implements the most common, two-way, commercial form of confidentiality agreement. There are more specialized forms, like pre-acquisition, that aren't covered.
