        "longDescription": "BillDog is a platform for mobile app monetization and growth: in-app purchases and subscriptions, paywalls, A/B testing, subscription analytics, push and in-app messaging, and in-app surveys, behind one SDK for iOS, Android, React Native, Flutter, Expo and the web.\n\nConnect your BillDog project to work on it in conversation.\n\nBuild and generate paywalls\n\u2022 Generate a mobile app paywall from a description, or start from a paywall template chosen by app category.\n\u2022 Edit copy, colors and layout, get a preview link, then publish when you are ready.\n\nSet up in-app purchases and subscriptions\n\u2022 Create products, entitlements, offerings and placements, one at a time or as a whole catalog in one step, with a dry run first.\n\u2022 Get warnings when a product has no App Store, Google Play or Stripe id for a platform you target.\n\nA/B test paywalls\n\u2022 Create a paywall A/B test, start and stop it, and read conversion, revenue per user, lift and significance for each variant.\n\nRead subscription analytics and mobile app analytics\n\u2022 Ask about revenue, MRR movement, churn, active subscriptions, retention, funnels and paywall conversion, in production or sandbox data.\n\nAdd BillDog and debug an integration\n\u2022 Get SDK setup code for iOS, Android, React Native, Flutter, Expo or web, with your project's public key.\n\u2022 Check what is missing from your setup, see whether your app is sending events and purchases, and see which paywall a placement will serve.\n\nEngage users\n\u2022 Draft in-app surveys, campaigns, journeys and push or in-app message templates, and manage feature flags.\n\nWho it is for: developers, founders and growth teams who build subscription apps and have a BillDog account with at least one project.\n\nWhat you control: you connect one project at a time and choose on the consent screen whether ChatGPT may read, create and edit, or also publish. New items start as drafts or inactive. Changes that affect real app users need the publish permission, and on a live project a publish waits for an owner or admin to approve it. Every change made through this connection is recorded in the project's audit log.\n\nLimitations:\n\u2022 It works only with a BillDog account and project. It does not sign in to App Store Connect, Google Play or Stripe, and does not create products there; it stores the ids you give it.\n\u2022 Your app still needs the BillDog SDK, added in your own code. ChatGPT can give you the setup code for your platform.\n\u2022 Surveys, campaigns and journeys are saved as drafts and activated in the BillDog dashboard.\n\u2022 It does not process payments, issue refunds or sell anything in ChatGPT, and it is not for getting past paywalls on websites.",
