What problem does it solve? Deciding whether to build a free tool (calculator, generator, analyzer) for marketing is risky without a framework — teams waste engineering effort on tools with no search demand, poor audience fit, or no path to their core product. This Skill provides a structured strategy for ideating, validating, scoping, and evaluating engineering-as-marketing tools. ## Core Features & Use Cases - Tool Ideation & Validation: Frameworks for finding pain points, checking search demand, and scoring ideas with an 8-factor evaluation scorecard. - Tool Type Guidance: Detailed reference covering calculators, generators, analyzers, testers, libraries, and interactive tools, with examples by industry (SaaS, agency, e-commerce, developer tools, finance). - Lead Capture & SEO Strategy: Gating options, lead capture best practices, keyword strategy, and build-vs-buy decisions (custom, no-code, or embedded). - Use Case: A SaaS founder wants to generate leads organically. Use this Skill to evaluate whether an ROI calculator is worth building, scope the MVP, and design the email capture flow. ## Quick Start Help me plan a free marketing tool for my product — evaluate the idea, recommend a tool type, and outline the MVP scope and lead capture strategy.
