Available Actions

Extract YouTube Transcript

This action retrieves the transcript (captions) from a specified YouTube video in your chosen language. It returns both a structured array of transcript segments and a plain text version.

Input Parameters

• video_url_or_id (required): The YouTube video URL (e.g., https://www.youtube.com/watch?v=dQw4w9WgXcQ) or just the video ID (e.g., dQw4w9WgXcQ).

• language (required): The language code for the transcript you want to extract (ISO 639-1 format, e.g., en for English, es for Spanish, etc.).

Supported languages include: en, es, de, fr, it, pt, ru, ja, zh, ar, hi, bn, ur, ko, nl, sv, no, da, fi, pl, el, tr, cs, hu, th, vi.

Output

• status: Indicates if the extraction was successful ("success") or failed ("error").

• message: A human-readable message about the result.

• transcript: An array of transcript segments (each with text, start time, and duration).

• transcript_text: The full transcript as a single plain text string.

• video_id: The YouTube video ID.

• video_url: The YouTube video URL.

Example Usage

Suppose you want to extract the English transcript from a YouTube video:

• video_url_or_id: https://www.youtube.com/watch?v=dQw4w9WgXcQ

The node will return:

• The transcript as an array (with timing and text for each segment).

• The full transcript as plain text.

• Status and message fields for error handling.

How to Connect and Use in a Workflow

1. Add the YouTube node to your workflow.

2. Set the required inputs (video URL/ID and language).

3. Connect the output to downstream nodes (e.g., an LLM node for summarization, or an Output node to display the transcript).

Example node reference in a prompt: If your YouTube node is action-0, you can reference the plain text transcript as {action-0.transcript_text} in downstream nodes to get the full text from the video.
