As far as I can tell, it's free for personal use, and paid if you want to build a product with it.
Seems very interesting, reminds me of wit.ai when I first started using it, but the training seems to work pretty well from some small examples (which I had trouble with using wit).
I was also hunting for pricing info, before deciding if I wanted to pursue something like this further. Is it determined on a case-by-case basis, or same for everyone? If same, any reason not to publish it somewhere on the website?
We are still evolving the exact pricing, so you should tell us about you and we will see what would be the best way to work together, we are happy about helping as many makers as we can ! contact us at contact@snips.ai
What's the pricing though? I have an impression this is a paid product, but no pricing info is present.
EDIT: also, in trained_assistant.json, what does "tfidf_vectorizer_vocab" represent, and why it includes words like "nazi" and "hitler"? ;).
