usability testing for AI-built products

About

Product manager at HallwayTest. I’m exploring how makers who build with Claude Code validate whether real users understand what they ship. Interested in AI-assisted product development, usability testing, and early-stage product research. Always happy to compare notes with builders working on real products.
