Drafts and Terminology work great together. If you are editing text in Drafts and have Terminology installed, when you select words you get two additional menu options: Te:Lookup and Te:Replace.

Te:Lookup will lookup your selection in Terminology’s dictionary, making it really easy to do further research on a word or phrase.

Te:Replace will also lookup your selection in Terminology, but with additional options to send back a replacement word. This allows you to browse through Terminology’s hierarchy of word relations and find just the right fit – then tap “< Send” and have the new word replaced inline in Drafts.
