Overview

Unlock Automated Audio Insights with this AI Agent

Tired of manually transcribing and summarizing your audio recordings like meetings, podcasts, or voice notes? This AI Agent acts as your automated assistant. When you drop an audio file into a designated Google Drive folder, it springs into action. First, it leverages OpenAI's Whisper for highly accurate audio transcription. Then, it uses a powerful GPT model (like GPT-4-turbo-preview, as configured in the template) to intelligently process the transcript. The AI extracts key information, structuring it into a JSON format that includes a title, concise summary, main points, action items (with date tagging for relative mentions), follow-ups, stories, references, arguments, related topics, and sentiment analysis. Finally, this structured goldmine of information is neatly organized and saved as a new page in your Notion workspace, ready for you or your team.

Key Features & Benefits

  • Automated Transcription: Utilizes OpenAI Whisper for fast and accurate speech-to-text conversion of various audio formats from Google Drive.
  • AI-Powered Summarization & Structuring: Employs advanced LLMs (e.g., GPT-4-turbo-preview) to generate comprehensive, structured summaries in JSON format, including sentiment, action items, and more, based on a customizable system prompt.
  • Seamless Google Drive Integration: Automatically triggers when new audio files are uploaded to a specified Google Drive folder.
  • Direct Notion Publishing: Creates new, organized pages in Notion with the AI-generated title and summary, building your knowledge base effortlessly.
  • Customizable AI Output: The OpenAI prompt for summarization can be tailored to adjust the desired output structure and specific information points you need.
  • Time-Saving Automation: Frees up valuable time spent on manual transcription and note-taking, allowing you to focus on strategic tasks.
  • Enhanced Content Accessibility: Makes audio content easily searchable, digestible, and actionable by converting it into structured text within Notion.

Use Cases

  • **B2C E-commerce**: Transcribe and summarize customer feedback calls or product review voicemails. Use the AI-generated insights (trends, sentiment, action items) to quickly enhance products or tailor marketing, with all findings organized in Notion for easy team access.
  • **B2B SaaS**: Automatically process sales demo recordings or client onboarding calls. This AI Agent extracts key discussion points, commitments, and follow-up actions from the audio, then logs them into a shared Notion database. This keeps sales and customer success teams aligned and boosts follow-through efficiency.
  • **Content Creators/Solopreneurs**: Convert podcast episodes, interviews, or voice memos into text transcripts and structured summaries for blog posts, show notes, or social media content, all organized within Notion.
  • **Founders/CTOs**: Transcribe and summarize internal strategy meetings or brainstorming sessions, ensuring key decisions and action items are captured and documented in a central Notion knowledge base.

Prerequisites

  • An n8n instance (Cloud or self-hosted).
  • OpenAI API Key with access to Whisper and a suitable chat model (e.g., gpt-4-turbo-preview is used in the template).
  • Google Drive account with OAuth2 credentials configured in n8n.
  • Notion account with API credentials configured in n8n.

Setup Instructions

  1. Download the n8n workflow JSON file.
  2. Import the workflow into your n8n instance.
  3. Configure the 'Google Drive Trigger' node: Authenticate your Google Drive account and specify the folder ID it should monitor for new audio files (e.g., 182i8n7kpsac79jf04WLYC4BV8W7E_w4E from the template).
  4. Configure the 'Google Drive' (download) node: Ensure it uses the same Google Drive credentials. It's set to download the file triggered by the previous node.
  5. Configure the 'OpenAI' (transcribe) node: Enter your OpenAI API Key. It's set to use the binary data property 'data' from the downloaded file for transcription via Whisper.
  6. Configure the 'OpenAI1' (summarize) node: Ensure your OpenAI API Key is set. Review and customize the system_prompt if needed to adjust the summary structure or content. The template uses gpt-4-turbo-preview; change if you prefer a different model.
  7. Configure the 'Notion' node: Authenticate your Notion account. You'll likely need to specify a parent page ID or database ID in Notion where new pages will be created (the Page ID field in the node). This workflow's Notion node is pre-configured to extract title and summary from a JSON object named audioContentSummary within the AI's response (e.g., {"audioContentSummary": {"title": "Meeting Title", "summary": "Key takeaways..."}}). The 'OpenAI1' node's system prompt aims to generate a structured JSON output; the example in the prompt uses exampleObject as the root key. You must either modify the system prompt in 'OpenAI1' to ensure the AI wraps its structured data within an audioContentSummary key, OR adjust the expressions in the 'Notion' node's 'Title' and 'Block UI' fields to match the AI's actual JSON output structure (e.g., JSON.parse($json.message.content).exampleObject.title).
  8. Test the workflow by uploading a sample audio file to your specified Google Drive folder.
  9. Activate the workflow.
