My honest review of AI Product Designer backed by Y-Combinator (v0 Users Need to See This)
Synopsis
Greg tests Polymet AI, a Y Combinator-backed AI product designer, against v0 by building a YouTube analytics prediction SaaS (TubePredict) inspired by a viral tweet. After three Polymet iterations and one v0 run, both produced usable designs: Polymet gave more detailed features and hover states plus code, v0 felt more polished and conversational. Both tools credit-based, ~250 free credits, ~50 per page.
