Evaluate product demand from product links, product descriptions, PRDs, websites, app-store pages, white papers, sales decks, screenshots, or funding materials using the demand triangle model: lack, target object, and consumer ability. Use when asked for demand assessment, pre-investment product review, growth diagnosis, positioning validation, competitor-backed demand evidence, or a multi-format demand report. Do not use for pure market sizing, generic business-model design, UX-only review, legal/financial advice, or ad-copy ideation without demand evidence.
