Earlier quoted context omitted.
No, PleaseAPI is converting Natural Language to Database like structures/commands with no need to have a human come up with every way you could say something because the vocabulary is built in. Unlike Wit it also offers the option to use the API's that are already integrated or Bring Your Own Backend so that you can have a mix of info/responses from your own system, or leverage what is already there.
Where can I sign up for that?
It will be on Mashape shortly, the Natural Language Part of Speech Tagger just went live Friday. Documentation takes time after we write code and is less fun to write. :-)
