# Build a KOOK AI Bot with Gemini

Source: https://langbot.app/docs/en/recipes/gemini/kook

Step-by-step guide to running a Gemini-powered AI bot on KOOK with LangBot: model setup, bot credentials, networking, testing and troubleshooting.

This recipe puts a Gemini model behind a KOOK bot. LangBot receives messages from KOOK, runs them through a pipeline, and sends the answer back, so you do not write any platform code.

Use Google's Gemini models with LangBot's built-in Agent, including image input when the model supports vision.

## What you need

- A running LangBot instance: [LangBot Cloud](https://space.langbot.app/cloud) (no server needed) or a [self-hosted deployment](https://langbot.app/docs/en/deploy/langbot/docker.md) with Docker or `uvx langbot`.
- A Gemini account or server you can call from LangBot.
- A bot created in the KOOK developer center and its **Bot Token**.

## Networking

The KOOK adapter only needs a bot token; LangBot connects out to KOOK.

## 1. Add the Gemini model

1. Create an API key in the Google Gemini console.
2. In LangBot, open **Models**, add an LLM model with the provider set to Google Gemini, then paste the API key and the model ID.
3. Enable **Tool Use** if the model supports function calling; MCP tools, Skills and the sandbox need it.
4. Create the key in Google AI Studio. Enable **Vision** on the model if you want the bot to read images.

## 2. Create a pipeline

Open **Pipelines** in the LangBot WebUI, create a pipeline (or edit the default one) and set **AI** as follows.

| Field           | Value                                                                  |
| --------------- | ---------------------------------------------------------------------- |
| Runner          | **Local Agent** (built-in Agent)                                       |
| Model           | The model you just added. You can add fallback models.                 |
| Prompt          | Instructions: who the bot is, tone, what it must not do.               |
| Knowledge Bases | Optional. Attach a knowledge base so answers come from your documents. |

## 3. Create the KOOK bot

1. Create a bot with the **KOOK** adapter and enter the Bot Token.
2. Grant the bot permissions and invite it to your server.

## 4. Bind and test

Open the bot, select the pipeline you created, save and make sure the bot is enabled.

Send a message that matches the trigger rules in a channel the bot can read.

## Troubleshooting

- Images are ignored: enable **Vision** on the model and check that the platform adapter forwards images.
- No reply in a channel: check the bot's channel permissions and the pipeline's group trigger rules.
- Check **Monitoring** in the WebUI: every message, pipeline run and error is recorded there.

## FAQ

### Do I need a server with a public IP for KOOK?

No. The KOOK adapter only needs a bot token; LangBot connects out to KOOK.

### Does the KOOK bot support streaming replies?

Check the [platform feature matrix](https://langbot.app/docs/en/insight/platform-features.md) for what this platform supports. Replies are delivered once the AI back end has finished.

### Can the same Gemini setup serve other platforms too?

Yes. A pipeline can be bound to many bots, so one configuration can answer on several platforms at once.
