+# Chat Providers
 
-This hub covers **model providers** (LLMs) and **messaging/chat providers** (WhatsApp, Telegram, etc).
-For model selection rules, see [/concepts/models](/concepts/models). For the full provider catalog, see
-[/concepts/model-providers](/concepts/model-providers).
+Clawdbot can talk to you on any chat app you already use. Each provider connects via the Gateway.
+Text is supported everywhere; media and reactions vary by provider.

+- Providers can run simultaneously; configure multiple and Clawdbot will route per chat.
+- Group behavior varies by provider; see [Groups](/concepts/groups).
+- DM pairing and allowlists are enforced for safety; see [Security](/gateway/security).
+- Model providers are documented separately; see [Model Providers](/providers/models).
