# Text, audio, and document nodes

> Prompts, notes, voice and sound, and PDF or text knowledge as inputs on the canvas.

These nodes feed words, sound, and knowledge into the rest of your graph. They live in the **Text**, **Audio**, and **Document** sections of the **Add Node** menu.

## Text block

**Text Block** node: a prompt or enrichment input. Wire it into a generator's prompt.

**Inputs → outputs:** optional image, audio, document, or video → text.

## Note / annotation

**Note / Annotation** node: a free-text note on the canvas, for comments and instructions to your team. Press `⌘B` for bold. A note never runs and isn't part of the graph.

## Audio reference

The **Audio Reference** node brings in voice or sound.

**Inputs → outputs:** none → audio.

## Document context

The **Document Context** node adds PDF or text knowledge to a generation.

**Inputs → outputs:** none → document.

## Try it

Bring a product spec into a generation:

1. Add a **Document Context** node from the **Document** section, and load your product one-pager PDF.
2. Connect it to a **Text Block** that describes the shot, such as "hero shot of the bottle with the three key benefits".
3. Connect the Text Block to an **Image Generation** node's prompt, and choose **Run Node**.

Add a **Note / Annotation** beside the graph, such as "Use approved product shots only", so teammates know the rules.

Or ask Claude or ChatGPT:

* "On my open canvas, add a prompt that reads 'hero shot of the bottle with the three key benefits' and connect it to the image generator."
* "Add a note to my canvas that says 'Use approved product shots only'."
