I looked at a couple of form tools first, but they all had the same problem: the client fills in something vague like "make it feel premium" and that's it, the form just accepts it. Then I'm the one who has to chase them for clarification two weeks later, usually mid-project when it's already a headache. ReqBrief actually catches that in the interview itself, if the client's answer is too vague, the AI asks a follow-up right then. By the time I get the brief, it's already specific enough to quote from. That's the whole reason I switched, it moved the clarification work to before the project starts instead of during it.
