What problem does it solve? Deciding whether to build a free tool (calculator, generator, analyzer) as a marketing channel is risky without a framework — teams over-engineer, pick ideas with no search demand, or build tools with no path to their product. This Skill provides a structured strategy for planning, validating, and scoping engineering-as-marketing tools. ## Core Features & Use Cases - Ideation & Validation Framework: Generate tool ideas from audience pain points and validate them against search demand, uniqueness, lead quality, and build feasibility. - Tool Type Guidance: Covers calculators, generators, analyzers, testers, libraries, and interactive tools, with industry-specific concept examples. - Benchmarks & Scorecard: Real case data (Unsplash, HubSpot Website Grader, Moz, Buffer, Shopify) and an 8-factor evaluation scorecard to justify the build. - Use Case: A SaaS founder wants to build a free ROI calculator to attract leads. Use this Skill to validate search demand, choose a gating strategy, scope the MVP, and score the idea before committing engineering time. ## Quick Start Help me evaluate whether building a free ROI calculator is a good lead generation strategy for my SaaS product.
