I Built an AI-Powered Subscription Dashboard in Kotlin with RevenueCat's Charts API

A developer built RC Pulse, a Kotlin/Ktor web app that connects to RevenueCat's Charts API to fetch live subscription metrics (MRR, active subscriptions, trials, revenue trends) and uses GPT-4o to generate plain-English briefings with actionable insights. The tool transforms raw subscription data into a dark-themed Chart.js dashboard paired with AI-generated analysis, demonstrated with real data from the Dark Noise app. It leverages RevenueCat's v2 Charts API endpoints with bearer token auth and a 5 req/min rate limit.
