Ask HN: Bot to increase documentation usage and reduce support effort. Useful?

Hi HN, We've built a prototype question answering bot in our team which can use your documentation as a knowledge base to answer questions asked by website visitors with 40% hard corrects and 20-30% soft corrects.

You simply put a Javascript chat plugin on your site, dump your documentation and it answers queries not unlike a domain expert even without keywords.

Here are a few (cherrypicked?) exchanges using Amazon Reviews as answers. It doesn't generate answers, but picks the best it can (out of 1000 total answers)

Would you pay 10 cents per response from this bot?
