Hailbell

Hailbell is in-app support chat plus push notifications for iOS, Android and web apps. Customers write from inside your app. An AI answers first from your docs and real prices, and you finish the reply from the dashboard, a Discord thread, Telegram or an AI agent over MCP. The customer gets a push when you answer. Each conversation shows the customer's plan, purchases, device and country. Hailbell can show an offer card that opens your paywall, and ask for an App Store review right after a problem is solved. Push campaigns go to iOS, Android and web in one send, with segments, each person's local time, quiet hours and daily caps. Native Swift and Kotlin SDKs and a web widget. Unlimited apps and seats. From $29/month, free for 14 days, no card required.
