Who wants AI in the conversation, with an owner
The AI suggests the next step. A person still closes.
The agent reads the conversation in Nexus, flags the next action, and waits for confirmation. Outside the 24-hour window, only Meta-approved templates go out. No bot running loose. No ChatGPT in a group.

Where AI leaks today
The suggestion shows up in the thread. Outside 24h, only an approved template.
A bot that never passes the ball
24h triage is a chatbot. An AI agent is something else: it suggests the step and a human confirms.
AI that replies and vanishes
With no owner and no deadline, the machine becomes one more invisible agent. Here every action has someone responsible.
ChatGPT loose, with no queue
That is MCP: the external AI operates Chatsac. The AI agent works inside the conversation, with a human in the loop.
Outside the 24h window, free text
Meta does not allow it. Outside the window the agent only fires an approved template. Free text only if the contact wrote just now.
Three intents, three URLs
Chatbot, AI agent, and MCP are not the same page.
Whoever searches for chatbot wants triage. Whoever searches for AI agent wants a human in the loop. MCP is the queue inside the external AI.
| Role | Chatbot | AI agent | MCP |
|---|---|---|---|
| What it does | Triage, booking, repeated questions | Suggests the next step in the conversation | The team's AI asks and acts on the queue |
| Who confirms | You define where the bot stops | Human in the loop, always | Operator in Claude, Grok, or ChatGPT |
| Where it lives | Flow in the panel | Inside WhatsApp, in Nexus | In the AI the team already opens |
| Outside 24h | Approved template only | Approved template only | Approved template only |
This is me
AI in the queue, with an owner and a deadline.
Suggestion, not an unsupervised blast
The operator sees the step and confirms. Nothing leaves the account without someone in the loop.
Conversation context, not a generic prompt
Score, ticket, and intent show up on the same panel as the message.
Outside 24h, templates only
Meta's rules apply. Free text only if the contact wrote right now.
Before the price
Take the risk out of the decision.
Does the agent replace the human?
No. It reads context, suggests the step, and waits for confirmation. Closing is still a person, with an owner and a deadline on the card.
Is it the same as a chatbot?
No. The chatbot handles first contact and transfers. The AI agent comes in when the conversation already exists and the next step needs judgment, not a fixed flow.
What about ChatGPT / Claude / Grok?
That is MCP: the external AI operates the queue. The AI agent works inside WhatsApp. Both exist. Do not mix them on the same URL.
Can the AI send messages on its own?
Only what the operator could already send. Outside the 24h window, only a Meta-approved template.
Do I need to know how to code?
No. The suggestion shows up in the conversation. The human confirms. No IT project for the basic flow.

What about ChatGPT, Claude, or Grok?
That is MCP: the external AI operates the queue. The AI agent works inside WhatsApp. Two different URLs.
Can the AI send messages on its own?

Do I need a new WhatsApp number?
No. You use the same number, now on the Official Meta API.
Is it official? Can my number be banned?
Yes, we are a Tech Provider on the Official Meta API. No platform promises immunity: Meta enforces the policy. On the official API you operate authorized and see the number quality.
