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

Text nodes

Text node showing rendered Markdown with a toolbar offering AI assistant, formatting, import, and download

A text node and its toolbar

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

Table nodes

Table node with the field mapping control showing which column is the text and which is the prompt

Column mapping on a 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.
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.
