# Text, table, and YouTube nodes

> Rewrite text, build tables, and summarize videos with the built-in AI assistants.

Three node types carry their own AI assistants. All of them can take connected references as input.

## Text nodes

</Frame>

<Tabs>
  <Tab title="AI assistant">
    The toolbar's AI button takes an instruction and produces a **new** node — text or table. You can
    ask for multiple outputs, and choose which agent handles it.
  </Tab>

  <Tab title="Generate and replace">
    The text generate panel rewrites or expands the text **in place**. Its prompt box explains that
    you can connect images, video, audio, and text nodes as references.

    If you connect a video reference, you are asked to pick an agent with video understanding.
  </Tab>
</Tabs>

Text nodes also handle documents: **import a document** to replace the content, and download the
content as Markdown, plain text, or Word.

## Table nodes

| Action                  | Result                                                                            |
| ----------------------- | --------------------------------------------------------------------------------- |
| **Edit table**          | Add and remove rows and columns, reorder rows, validate column names              |
| **AI assistant**        | Produces a text node from the table                                               |
| **AI table generation** | Rewrites the table in place                                                       |
| **Field mapping**       | Choose which column is the text, which is the prompt, and which rows are included |
| **Upload a table file** | From a text node's toolbar, creates a new table node                              |

Field mapping is what makes a table useful: it tells WJI which column to treat as the prompt when
you drag connections out of the table to create one generation node per row.

## YouTube nodes

Paste a YouTube link onto the canvas and a YouTube node appears with the video embedded.

Its AI assistant takes an instruction — summarize, rewrite, turn into a script — and produces a text
node named after the video. It requires an agent with video understanding, so the automatic agent is
not offered.

<Tip>
  A common workflow: paste a reference video from YouTube, ask the assistant for a shot-by-shot
  breakdown, then drag out of the resulting text node to create generation nodes that already carry
  the description as context.
