What problem does it solve? Free users often never convert because upgrade prompts appear at the wrong time, show weak value propositions, or use pushy dark patterns that erode trust. This Skill provides a structured framework for designing in-app paywalls and upgrade flows that convert users after they have experienced real value. ## Core Features & Use Cases - Trigger Point Design: Guidance for feature gates, usage limits, trial expiration, and time-based prompts, with timing and frequency rules to avoid annoying users. - Paywall Screen Components: A reusable structure covering headline, value demonstration, plan comparison, pricing, social proof, CTA, and escape hatch, with copy templates for each paywall type. - A/B Testing Playbook: A references file with experiment ideas across trigger timing, pricing presentation, copy, trial structure, personalization, and frequency capping. - 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, and a clear "Maybe Later" escape hatch. ## Quick Start Ask the AI to design an upgrade screen for when free users hit your plan's usage limit, including headline, plan comparison, and CTA copy.
