What problem does it solve? Free users often never convert to paid plans 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 Design Frameworks: Provides screen component templates (headline, value demonstration, plan comparison, social proof, CTA, escape hatch) for feature gates, usage limits, and trial expiration moments. - Trigger Timing & Frequency Rules: Defines when to show upgrade prompts (after aha moments, at genuine limits) and how to cap frequency to avoid frustrating users. - A/B Testing Playbook: Ships a references/experiments.md catalog of tests covering triggers, pricing presentation, copy, trials, personalization, and dismiss behavior. - Use Case: When a free user hits the 3-project limit in your project management tool, use this Skill to design the upgrade screen with benefit-focused copy, a free-vs-pro comparison, and a clear escape hatch. ## Quick Start Ask the assistant to design an upgrade paywall for when free users hit your plan's usage limit, including copy and layout recommendations.
