AI Product Idea Critique Prompt

Act as a brutally honest product reviewer. My idea is [IDEA], intended users are [USERS], problem being solved is [PROBLEM], expected value is [VALUE], competitors are [COMPETITORS], resources available are [RESOURCES], and my biggest assumption is [ASSUMPTION]. Try to prove that this idea will fail. Research competing solutions, user demand, technical difficulty, monetization potential, adoption barriers and market risks. Identify what I may be overlooking, which assumptions require evidence, what would make the idea stronger, and what I should change before investing more time or money. Do not praise the idea unless the evidence supports it.
