We've spent the last few months developing a product, but now we've hit a wall and we're thinking about abandoning it. We'd appreciate your brutally honest feedback about what we should do and if our solution makes any sense at all.

For context, here is our YC startup school presentation, and our landing page:

Basically, we made an editor that tries to solve document versioning issues. While trying to find product market fit, we've separately tested it with different target groups, like writers, journalists, lawyers, academics and digital content creators. We kept getting great feedback from these groups, but had a hard time converting any actual users. We had to stop developing because while trying to sell it, everyone kept requesting more and more different features, and it seemed no matter what we would add, still no one was ready to pay for it.

Do you think there is any scenario where someone would find this useful enough to actually use it or pay money for it? Or did we just build something that seems interesting to a lot of people but no one is really willing to use it?
