How it works

This advanced workflow transforms your long-form audio content (like podcast episodes or webinar recordings) into digestible, ready-to-use marketing assets. It's designed for podcasters, content creators, and marketers who want to maximize their content's reach. It automatically:

  • Takes a full transcript of your audio/video content as input.

  • Generates a concise, comprehensive summary of the episode using advanced AI.

  • Extracts a list of key topics and keywords from the transcript, perfect for SEO, tagging, and content categorization.

  • Delivers the summary and keywords directly to your inbox or a connected tool for easy access.

Streamline your content repurposing pipeline and unlock new value from your audio and video assets with intelligent automation!

Set up steps

Setting up this powerful workflow typically takes around 20-30 minutes, as it involves multiple AI steps. You'll need to:

  • Obtain API keys for your preferred AI service (e.g., OpenAI, Google AI).

  • Have access to a method for generating transcripts from your audio/video (e.g., manually pasting, or using a separate transcription service like AssemblyAI, Whisper, etc.).

  • Connect your preferred email service (e.g., Gmail) to receive the output.

All detailed setup instructions and specific configuration guidance are provided within the workflow itself using sticky notes.

Generate Podcast Transcript Summaries and Keywords with OpenAI and Gmail

This n8n workflow automates the process of generating summaries and keywords for podcast transcripts using OpenAI, and then sends the results via Gmail. It's designed to streamline content creation and make podcast information more accessible.

What it does

This workflow simplifies the process of extracting key information from podcast transcripts:

  1. Manual Trigger: The workflow is initiated manually, allowing you to control when the process starts.
  2. Edit Fields (Set): This node is currently an empty placeholder. In a complete workflow, it would typically be used to define or modify input data, such as the raw podcast transcript or other parameters needed for processing.
  3. OpenAI: This node connects to the OpenAI API to process the transcript. It would be configured to send the transcript to OpenAI's language models (e.g., GPT-3.5 or GPT-4) to generate a concise summary and a list of relevant keywords.
  4. Gmail: The final step sends an email containing the generated summary and keywords. This email could be sent to a content manager, editor, or directly to a publishing platform for review.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance (self-hosted or cloud).
  • OpenAI API Key: An API key for OpenAI to access their language models.
  • Gmail Account: A configured Gmail account credential in n8n to send emails.

Setup/Usage

  1. Import the Workflow:
    • Copy the provided JSON code.
    • In your n8n instance, click "New" in the workflows section.
    • Click the three-dot menu (...) and select "Import from JSON".
    • Paste the JSON code and click "Import".
  2. Configure Credentials:
    • OpenAI Node: Click on the "OpenAI" node and configure your OpenAI API Key credential.
    • Gmail Node: Click on the "Gmail" node and configure your Gmail account credential.
  3. Configure Input Data (Edit Fields):
    • The "Edit Fields (Set)" node is currently empty. You will need to modify this node to provide the podcast transcript or a URL to the transcript that OpenAI should process. For example, you might add a field named transcript with the full text of the podcast.
  4. Configure OpenAI Prompt:
    • Open the "OpenAI" node.
    • Adjust the "Prompt" field to instruct OpenAI on how to summarize and extract keywords. For example: 
      "Please provide a concise summary and a list of 5-10 keywords for the following podcast transcript:\n\n{{ $json.transcript }}"
      (Assuming you named your transcript field transcript in the "Edit Fields" node).
  5. Configure Gmail Email:
    • Open the "Gmail" node.
    • Set the "To" address for where you want the summary and keywords to be sent.
    • Customize the "Subject" and "Body" of the email using expressions to include the output from the OpenAI node (e.g., {{ $json.choices[0].message.content }}).
  6. Activate and Execute:
    • Save the workflow.
    • Click "Activate" to enable the workflow.
    • Click "Execute Workflow" on the "Manual Trigger" node to run it.

Key settings: pricebook2Id (hardcoded in script): e.g., 01sxxxxxxxxxxxxxxx Source lines: $('Message a model').first().json.message.content.products Output: { soql, codes } --- 8) Query PricebookEntries (Salesforce) Purpose: Fetch PricebookEntry.Id for each Product2.ProductCode. Key settings: Resource: search Query: ={{ $json.soql }} Creds: salesforceOAuth2Api Output: Items with Id, Product2.ProductCode (used for mapping). --- 9) Code in JavaScript (Build OLI payloads) Purpose: Join lines with PBE results and Opportunity Id ➜ build OpportunityLineItem payloads. Inputs: OpportunityId: ={{ $('Create an opportunity').first().json.id }} Lines: ={{ $('Message a model').first().json.message.content.products }} PBE rows: from previous node items Output: { body: { allOrNone:false, records:[{ OpportunityLineItem... }] } } Notes: Converts discount_total ➜ per-unit if needed (currently commented for standard pricing). Throws on missing PBE mapping or empty lines. --- 10) Create Opportunity Line Items (HTTP Request) Purpose: Bulk create OLIs via Salesforce Composite API. Key settings: Method: POST URL: https://<your-instance>.my.salesforce.com/services/data/v65.0/composite/sobjects Auth: salesforceOAuth2Api (predefined credential) Body (JSON): ={{ $json.body }} Output: Composite API results (per-record statuses). --- 11) Update File to One Drive Purpose: Archive the original PDF in OneDrive.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
