What problem does it solve? Free users often never convert to paid because upgrade prompts appear at the wrong time, communicate weak value, or use pushy patterns that erode trust. This Skill provides structured guidance for designing in-app paywalls and upgrade flows that convert without annoying users. ## Core Features & Use Cases - Paywall Type Frameworks: Ready-made structures for feature gates, usage limits, trial expiration, and time-based prompts, each with headline, value demonstration, comparison, CTA, and escape hatch components. - Timing and Frequency Rules: Guidance on when to show upgrade prompts (after aha moments, at genuine limits) and how to cap frequency to avoid fatigue. - A/B Testing Catalog: A references file with experiment ideas covering triggers, pricing presentation, copy, trials, personalization, and dismiss behavior. - Use Case: When a free user tries to create a 4th project on a 3-project plan, generate a usage-limit paywall with benefit-focused copy, a free-vs-pro comparison, social proof, and a clear "Maybe later" option. ## Quick Start Ask the assistant to design an upgrade paywall for your product's specific trigger point, such as a usage limit or trial expiration, including copy and layout recommendations.
