Would you back a narrow creative-notes app built around voice capture?

I’m working on Tapestry, an iPhone app for creative people who think out loud before they can write something polished. The product takes a natural spoken session, transcribes it, and pulls out useful pieces such as connections, constraints, questions, techniques, and next steps. The bet is that voice is a better first input for certain creative workflows, but normal voice memos fail because they become a messy archive. Target users right now: writers, artists, designers, makers, and creative founders. The market question I’m trying to pressure-test: Is this too niche, or is “voice-first creative capture” a strong wedge into a broader notes/productivity space? Would you focus acquisition on creators/writers, productivity/PKM users, or app builders looking for better idea capture?
