How It Works

Section titled “How It Works”

WhatsApp messages are routed to Claude Code sessions the same way Telegram messages are. The agent responds naturally, and replies appear in WhatsApp.

The key difference from Telegram: WhatsApp doesn’t have forum topics, so conversations are threaded differently internally but the user experience is seamless.
