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.\n\nWho\u2019s it for\nThis 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.\n\nWhat it does\nThis workflow automates the entire process of turning spoken words from a meeting into actionable tasks for your team.\n\nTrigger 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.\n\nTranscribe Audio: It takes the audio file and uses Google Gemini to generate a full text transcript of the recording.\n\nExtract 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.\n\nFormat 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.\n\nSend 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.\n\nHow to set up\nConfigure Credentials: Ensure you have configured your credentials for Google Drive, Google Gemini, and Slack in n8n.\n\nSet Google Drive Folder: In the \"Looking for uploading file\" node, select the Google Drive folder you want the workflow to monitor.\n\nSet 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.\n\nActivate Workflow: Save your changes and activate the workflow using the toggle at the top right.\n\nTest It: Upload a meeting recording to the designated Google Drive folder to see the magic happen!\n\nHow to customize the workflow\nChange 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.\n\nModify 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.\n\nChange Notification Service: Replace the Slack node with another notification service like Discord, Microsoft Teams, or an email node.\n\nArchive 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."
