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.

n8n Workflow: Extract Meeting To-Do Lists from Audio with Google Gemini and Send to Slack

This n8n workflow automates the process of extracting actionable to-do items from audio meeting transcripts (or any audio file) using Google Gemini and then sending these items to a designated Slack channel. It's designed to streamline post-meeting follow-ups and ensure tasks are captured efficiently.

What it does

  1. Monitors Google Drive: Listens for new audio files (e.g., meeting recordings) uploaded to a specified Google Drive folder.
  2. Transcribes Audio (Implicit): Although not explicitly shown in the provided JSON, it's implied that a preceding step (or the Google Gemini node itself, if configured for audio processing) would transcribe the audio file into text.
  3. Extracts To-Do Items with Google Gemini: Uses the Google Gemini AI model to analyze the transcribed text and identify key action items, tasks, or to-do lists.
  4. Formats Output: Prepares the extracted to-do items into a readable format.
  5. Sends to Slack: Posts the extracted to-do list to a specified Slack channel, making it easy for team members to see and track action items.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • Google Drive Account: Configured with a credential in n8n to monitor for new audio files.
  • Google Gemini API Key: Configured as a credential in n8n for accessing the Gemini AI model.
  • Slack Account: Configured with a credential in n8n to post messages to a channel.

Setup/Usage

  1. Import the Workflow:
    • Download the provided JSON file.
    • In your n8n instance, go to "Workflows" and click "New".
    • Click the "Import from JSON" button and paste the workflow JSON or upload the file.
  2. Configure Credentials:
    • Locate the "Google Drive Trigger" node and configure your Google Drive credential. Specify the folder you want to monitor for new audio files.
    • Locate the "Google Gemini" node and configure your Google Gemini API credential.
    • Locate the "Slack" node and configure your Slack credential. Specify the channel where you want the to-do lists to be posted.
  3. Activate the Workflow: Once all credentials are set up and the workflow is configured, activate it.

The workflow will now automatically trigger whenever a new audio file is added to your specified Google Drive folder, process it with Google Gemini, and send the extracted to-do list to Slack.

AI-powered code review with linting, red-marked corrections in Google Sheets & Slack

Advanced Code Review Automation (AI + Lint + Slack) Who’s it for For software engineers, QA teams, and tech leads who want to automate intelligent code reviews with both AI-driven suggestions and rule-based linting — all managed in Google Sheets with instant Slack summaries. How it works This workflow performs a two-layer review system: Lint Check: Runs a lightweight static analysis to find common issues (e.g., use of var, console.log, unbalanced braces). AI Review: Sends valid code to Gemini AI, which provides human-like review feedback with severity classification (Critical, Major, Minor) and visual highlights (red/orange tags). Formatter: Combines lint and AI results, calculating an overall score (0–10). Aggregator: Summarizes results for quick comparison. Google Sheets Writer: Appends results to your review log. Slack Notification: Posts a concise summary (e.g., number of issues and average score) to your team’s channel. How to set up Connect Google Sheets and Slack credentials in n8n. Replace placeholders (<YOURSPREADSHEETID>, <YOURSHEETGIDORNAME>, <YOURSLACKCHANNEL_ID>). Adjust the AI review prompt or lint rules as needed. Activate the workflow — reviews will start automatically whenever new code is added to the sheet. Requirements Google Sheets and Slack integrations enabled A configured AI node (Gemini, OpenAI, or compatible) Proper permissions to write to your target Google Sheet How to customize Add more linting rules (naming conventions, spacing, forbidden APIs) Extend the AI prompt for project-specific guidelines Customize the Slack message formatting Export analytics to a dashboard (e.g., Notion or Data Studio) Why it’s valuable This workflow brings realistic, team-oriented AI-assisted code review to n8n — combining the speed of automated linting with the nuance of human-style feedback.
