What you can ask
Three things ChatGPT can do today.
- 01
A Custom GPT for your sales team
Build it once. Your team uses it from chat. They ask: who messaged us today? The GPT pulls Instagram DMs and WhatsApp chats in one view.
- 02
Send WhatsApp replies from Actions
Pick the send-message action. ChatGPT asks before each send. You stay in the loop. Your team gets a WhatsApp AI agent without writing code.
- 03
Analytics on demand
Ask: what was my reply time last week. ChatGPT pulls it from the analytics endpoint and gives you a clean summary.
