Extract meeting to-do lists from audio with Google Gemini and send to Slack

This workflow automates the process of converting audio meeting recordings into a structured to-do list. It listens for new audio files in a Google Drive folder, transcribes them, extracts action items using AI, and sends a formatted list to a designated Slack channel.

Who’s it for

This template is perfect for project managers, teams, and anyone who wants to save time on post-meeting administrative tasks. If you record your meetings and use Google Drive for storage and Slack for team communication, this workflow will streamline your follow-up process and ensure no action item is missed.

What it does

This workflow automates the entire process of turning spoken words from a meeting into actionable tasks for your team.

1. Trigger on New Audio: The workflow starts automatically when you upload a new audio file (e.g., MP3, M4A, WAV) to a specific folder in your Google Drive.
2. Transcribe Audio: It takes the audio file and uses Google Gemini to generate a full text transcript of the recording.
3. Extract To-Do Items: The transcript is then passed to another Google Gemini node with a specialized prompt. This prompt instructs the AI to carefully analyze the text and extract all action items.
4. Format Output: The AI formats the extracted tasks into a clean JSON array. Each task includes a description, the assigned person, a deadline, and its priority.
5. Send to Slack: Finally, the workflow sends the structured to-do list as a message to your specified Slack channel, making it easy for the whole team to see and act upon.

How to set up

1. Configure Credentials: Ensure you have configured your credentials for Google Drive, Google Gemini, and Slack in n8n.
2. Set Google Drive Folder: In the "Looking for uploading file" node, select the Google Drive folder you want the workflow to monitor.
3. Set Slack Channel: In the "Send a message" node, choose the correct Slack account and select the channel where you want the to-do list to be posted.
4. Activate Workflow: Save your changes and activate the workflow using the toggle at the top right.
5. Test It: Upload a meeting recording to the designated Google Drive folder to see the magic happen!

How to customize the workflow

• Change AI Model: You can easily swap the Google Gemini nodes for other AI models like OpenAI or Anthropic to handle transcription and analysis based on your preference.
• Modify the AI Prompt: Adjust the prompt in the "Analyze document" node to change the output format. For example, you could ask for a meeting summary in addition to the to-do list.
• Change Notification Service: Replace the Slack node with another notification service like Discord, Microsoft Teams, or an email node.
• Archive Results: Add a node (e.g., Google Sheets, Notion, Airtable) after the "Analyze document" node to save a history of all meeting transcripts and their corresponding action items.
