It looks like it's designed for the IDE use case - on cursory inspection of the code, it contains an autocomplete database and a client-server architecture designed for editor plugins (with useful interfaces like "type at character index"). I'm surprised that they don't seem to have launched with a public editor plugin and that the documentation doesn't seem to mention it.
