# AI nodes

AI nodes are the creative engines of your flow. They generate and transform content using state-of-the-art AI models for images, video, and audio.

You'll find these nodes under **Use AI** in the [node picker](/build-your-system/studio/toolbar.md).

### Basics

The most important AI nodes are the following:

* **Generate text**: Creates written content using large language models (LLMs). Perfect for prompt enhancing, media or written material analysis, ad copy, or any text-based marketing content.
* **Generate image**: Produces visual content using the best image generation models available.
* **Generate video**: Creates video content using the best video models available.
* **Generate audio**: Generates voices or sound design with AI.
