# Chatbot and AI: overview

_The three generations of automatic WhatsApp service in TecPet — legacy chatbot, new chatbot and Artificial Intelligence — and where to configure them._

TecPet serves your customers **automatically on WhatsApp**. Today this comes in three "generations":

- **[Legacy chatbot](/en/configuracao/chatbot/chatbot-antigo/)** — the older version. It **has no settings screen**: the **support team** sets up the flows. We're migrating shops gradually.
- **[New chatbot](/en/configuracao/chatbot/novo-chatbot/)** — you build the service yourself (messages, action menu, data collection, booking) on a **visual screen**, without AI: replies follow exactly what you set.
- **[Artificial Intelligence (AI)](/en/configuracao/chatbot/inteligencia-artificial/)** — the new chatbot **supercharged with AI**: it understands text and audio, replies in natural language and even **books by voice**.

> The **new chatbot** and the **AI** use **the same screen** — AI is just one extra switch. So configuring one already gets the other ready.

## Where to configure

Under **Settings → IA → Atendimento**.

This menu **only shows up** for those already on the **new chatbot** or **AI**. If your shop still uses the **legacy chatbot**, it won't appear — [talk to support](/en/configuracao/chatbot/chatbot-antigo/) to migrate.

## The service modes

At the top of the screen you choose **how the bot behaves**:

- **Off** — the bot replies nothing.
- **Auto Reply** — always replies with **a single standard message** (no menu or flow).
- **Simulation** — lets you **test and tune** the flows **without sending anything for real**.
- **Self Service** — the bot **live in production**, replying for real per your flows.

## Quick comparison
