What problem does it solve? Free users often never convert because in-app paywalls appear at the wrong moment, communicate weak value, or use pushy patterns that erode trust. This Skill provides structured frameworks for designing upgrade screens, feature gates, usage-limit prompts, and trial expiration flows that convert without annoying users. ## Core Features & Use Cases - Paywall Type Frameworks: Ready-made structures for feature lock, usage limit, and trial expiration paywalls, including headline, value demonstration, comparison, social proof, CTA, and escape hatch components. - Timing & Frequency Rules: Guidance on when to trigger upgrade prompts (after aha moments, at genuine limits) and how to cap frequency to avoid frustrating users. - A/B Testing Playbook: A references file with dozens of experiment ideas covering triggers, pricing presentation, copy, trials, personalization, and dismiss behavior. - Use Case: A product manager notices trial-to-paid conversion is only 2%. The Skill diagnoses the weak value proposition, recommends showing what users accomplished during the trial, applies loss framing, and proposes specific redesign copy. ## 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.
