The short answer

DialogBrain is an AI agent that answers customers across the messaging accounts you already have: Telegram, WhatsApp, email, Instagram, Messenger, voice calls and more, 22 in all, with drafts your team approves before they're sent. DevReply is a native chat inside your iOS and Android app, answered from one inbox, with an MCP server so your own agent can work that inbox and set the app up. If your customers write to you on messengers and social networks, DialogBrain reaches far more of them. If they're inside your mobile app, DevReply puts the chat right there.

For a single channel, DialogBrain's base is lower than DevReply Pro. Its bill grows with channels, seats and AI use; DevReply's grows only with conversations.

Why DevReply for mobile apps

DialogBrain meets customers in the apps they already use: messengers, social networks, email, the phone. That's its strength. But an app user stuck on a broken purchase is inside your app, not in Telegram, and that's where DevReply works:
