What problem does it solve? Free users often never convert to paid plans because paywalls appear at the wrong time, communicate weak value, or create friction. This Skill provides structured guidance for designing in-app paywalls, upgrade modals, and feature gates that convert users after they have experienced product value. ## Core Features & Use Cases - Paywall Design Patterns: Provides templates and component checklists for feature-lock, usage-limit, and trial-expiration paywalls, including headlines, CTAs, pricing display, and escape hatches. - Trigger and Timing Strategy: Defines when to show upgrade prompts (after aha moments, at genuine limits) and frequency rules to avoid annoying users. - A/B Testing Playbook: Ships a references/experiments.md catalog of test ideas covering triggers, layouts, pricing presentation, copy, trials, and personalization. - Use Case: A SaaS team notices low trial-to-paid conversion. Use this Skill to redesign the trial expiration screen with value summaries, early warnings, and a clear upgrade path, then select experiments to validate the changes. ## Quick Start Ask the AI to design an upgrade modal for users who hit the free plan's project limit, including headline, feature comparison, pricing, and CTA.
