Hailbell

Native in-app support chat and push notifications for iOS, Android, and web with AI-powered replies.

Overview

Hailbell is an in-app support platform that combines chat, push notifications, and AI into a single SDK for iOS, Android, Flutter, React Native, and web applications. It enables developers to answer customer questions automatically using AI trained on their app's pricing and documentation, while providing a unified inbox for manual replies via the dashboard, Discord, or Telegram.

The platform is designed to reduce churn and increase revenue by allowing teams to send targeted push notifications with local time and weather variables, request reviews at optimal moments, and offer paywall deals directly within the chat. Every conversation includes customer context—plan, purchases, location, and device information—to help teams make informed decisions about retention and upselling.

Setup takes about ten minutes and requires no backend infrastructure beyond uploading push keys. The service includes a 14-day free trial and offers a 14-day money-back guarantee on paid plans.
