Here's my feedback - I'm someone who actually has surprising amounts of pain maintaining my FAQ so your product is appealing:

- I want to see screenshots of your mobile presentation of the faq. I also want to understand that it'll be easy to integrate with my app. (Ideally native - I don't trust web based interactive elements on mobile)

- I want FAQ localization somehow.

- Customize FAQ based on parameters of the user (if they've indicated they want to use certain "slices" of my app, I either only want to show those slices, or at least to prioritize them so they show up first)

Neat idea!
