PM field guide: building the same CRM in Lovable, AI Studio, and Claude
PawelHuryn · x · 2026-11-16
Pawel Huryn published an AI prototyping field guide, building the same simple CRM live in four tools with a group of PMs:
- Context: Meta PMs now vibe-code prototypes and demo them to Zuckerberg; product sense interviews include a live prototyping round. Figma-then-weeks-of-dev is giving way to working prototypes in a prompt or two
- Tool division of labor: Lovable is fastest prompt-to-published; Google AI Studio is good enough; Claude Design makes the best-looking prototype with a ceiling; Claude Code yields a real app
- Method: iterate, don't spec; a context prompt beats a spec; run a security check before sharing links; instrument prototypes for validation
