What problem does it solve? Free users often never convert because in-app paywalls and upgrade prompts are poorly timed, generic, or pushy. This Skill provides structured frameworks for designing upgrade screens, feature gates, usage-limit prompts, and trial expiration flows that convert without damaging user trust. ## Core Features & Use Cases - Paywall Screen Design: Provides component-level guidance for headlines, value demonstrations, plan comparisons, social proof, CTAs, and escape hatches across feature lock, usage limit, and trial expiration paywall types. - Trigger Timing & Frequency Rules: Defines when to show upgrade prompts (after aha moments, at genuine limits) and when not to (during onboarding, mid-flow), with frequency capping and cool-down rules. - A/B Testing Playbook: Ships a references/experiments.md catalog of test ideas covering triggers, layouts, pricing presentation, copy, trials, personalization, and dismiss behavior. - Use Case: A product manager whose trial expiration screen converts at 2% gets a diagnosis of why it underperforms plus a redesigned flow using loss framing, accomplishment summaries, and plan options. ## Quick Start Ask the assistant to design an upgrade paywall for when free users hit your product's usage limit, including copy and layout recommendations.
