This is a great project and tutorial. IMHO you have a value prop that's much larger/better than what you're describing here.
To me it sounds like you're creating a data mining annotation tool that can work on any large corpus of free-form documents that have discoverable labels, such as medical records, legal cases, press releases, SEC filings, customer reviews, etc.
Can you speak to any of these? And do you have a pitch deck or similar ask for funding/help/advisors?
