Turn a video link and transcript into a ready YouTube title, description, tags, and hashtags. Marketing teams and creators use it to speed up edits and keep brand links the same in every video. It fits shops, memberships, and promo content where clear offers and calls to action matter.

A simple web form collects the video URL, the transcript, and focus keywords. An AI agent, powered by OpenAI, writes SEO ready metadata and pulls your approved links from a single Google Doc. A structured parser checks the output and keeps fields clean and predictable. The flow extracts the video ID from the link, formats tags as a list, and updates the video through the YouTube API. A final confirmation screen shows the updated title.

Setup is straightforward. Connect OpenAI, Google Docs, and YouTube in n8n, then point the tool to your brand links document. Most teams cut manual edits from about 30 minutes to around 2 minutes per video and reduce copy paste mistakes. You can adjust category and region to match your channel. It also gives non technical teammates a simple form to manage metadata without entering YouTube Studio.

1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
2. You'll need accounts with OpenAI, Google Docs and YouTube. See the Tools Required section above for links to create accounts with these services.
3. Open the On form submission node and review the form fields. Ensure YouTube Video Link and Video Transcript are required, and keep Focus Keywords optional if desired. Save the button label and form title to match your brand.
4. Connect OpenAI: Double click the OpenAI Chat Model node, choose Credential to connect with, click Create new credential, then paste your OpenAI API key from your OpenAI account. Save and test the node with a sample prompt.
5. Connect Google Docs: Double click the googleDocsTool node, in the Credential dropdown click Create new credential, then follow the on screen steps to allow access to your Google account. Replace the document ID with your own links document and make sure the Google account has access.
6. Connect YouTube: Double click the YouTube node, create a new YouTube credential, sign in with the Google account that manages the target channel, and grant the requested scopes. Confirm you can see and update videos for that channel.
7. Update constants: In the YouTube node, set categoryId and regionCode to match your channel. Adjust the appended links in the description if you want different social or promo links.
8. Check tag formatting: Open the Format Tags node and confirm tags are joined by commas. Adjust if your team prefers a different delimiter.
9. Review the AI agent prompt: Open the Youtube Meta Generator node and tune tone, target audience, and call to action. Keep the output structure so the parser can read it.
10. Replace the links source: In your Google Doc, list affiliate links, course links, and social profiles exactly as you want them to appear in every description.
11. Activate and test: Turn the workflow on. Open the form URL, paste a valid YouTube video link from the connected channel, add the transcript and keywords, then submit. Watch the final confirmation and verify the update in YouTube Studio.
12. Troubleshoot: If the update fails, confirm the video belongs to the connected channel and the link format is valid. If text looks wrong, check the Google Doc content and the AI prompt. Reconnect credentials if you see auth errors.
