🎤 Audio-to-Insights: Auto Meeting Summarizer

Transform your meeting recordings into actionable insights automatically. This powerful n8n workflow monitors your Google Drive for new audio files, transcribes them using OpenAI's Whisper, generates intelligent summaries with ChatGPT, and logs everything in Google Sheets - all without lifting a finger.

🔄 How It Works

This workflow operates as a seamless 6-step automation pipeline:

Step 1: Smart Detection The workflow continuously monitors a designated Google Drive folder (polls every minute) for newly uploaded audio files.

Step 2: Secure Download When a new audio file is detected, the system automatically downloads it from Google Drive for processing.

Step 3: AI Transcription OpenAI's Whisper technology converts your audio recording into accurate text transcription, supporting multiple audio formats.

Step 4: Intelligent Summarization ChatGPT processes the transcript using a specialized prompt that extracts:

Key discussion points and decisions
Action items with assigned persons and deadlines
Priority levels and follow-up tasks
Clean, professional formatting

Step 5: Timestamp Generation The system automatically adds the current date and formats it consistently for tracking purposes.

Step 6: Automated Logging The final summary is appended to your Google Sheets document with the date, creating a searchable archive of all meeting insights.

Auto Meeting Summarizer with Google Drive, OpenAI Whisper & GPT-4 to Google Sheets

This n8n workflow automates the process of transcribing audio files from Google Drive, summarizing them using OpenAI's GPT-4, and storing the summaries in a Google Sheet. It's ideal for automatically processing meeting recordings, voicemails, or any audio content saved to Google Drive.

What it does

This workflow streamlines the process of extracting insights from audio files by:

Monitors Google Drive: It triggers whenever a new file (specifically an audio file) is added to a designated folder in Google Drive.
Transcribes Audio: It sends the newly added audio file to OpenAI's Whisper model for transcription, converting speech to text.
Summarizes Transcript: The transcribed text is then sent to OpenAI's GPT-4 model to generate a concise summary.
Extracts Key Information: It also uses GPT-4 to extract the meeting's title and a list of action items from the summary.
Formats Date & Time: It converts the current timestamp into a user-friendly date format for the summary.
Records to Google Sheets: Finally, it appends a new row to a specified Google Sheet, including the original file name, the generated summary, extracted title, action items, and the date.

Prerequisites/Requirements

To use this workflow, you will need:

n8n Account: A running instance of n8n.
Google Drive Account: Configured with a designated folder for audio file uploads.
Google Sheets Account: A Google Sheet set up with columns for "File Name", "Summary", "Title", "Action Items", and "Date".
OpenAI API Key: With access to both the Whisper (audio transcription) and GPT-4 (text summarization and extraction) models.

Setup/Usage

Import the workflow: Import the provided JSON into your n8n instance.
Configure Credentials:
- Google Drive Trigger: Configure your Google Drive credentials and specify the folder ID you want to monitor for new audio files.
- OpenAI Node: Configure your OpenAI API key. Ensure it has access to both Whisper and GPT-4 models.
- Google Sheets Node: Configure your Google Sheets credentials and specify the Spreadsheet ID and Sheet Name where the summaries should be appended.
Activate the workflow: Once configured, activate the workflow.

Now, whenever an audio file is uploaded to the specified Google Drive folder, the workflow will automatically transcribe, summarize, extract key information, and log it in your Google Sheet.

Automated UGC video generator with Gemini images and SORA 2

This workflow automates the creation of user-generated-content-style product videos by combining Gemini's image generation with OpenAI's SORA 2 video generation. It accepts webhook requests with product descriptions, generates images and videos, stores them in Google Drive, and logs all outputs to Google Sheets for easy tracking. Main Use Cases Automate product video creation for e-commerce catalogs and social media. Generate UGC-style content at scale without manual design work. Create engaging video content from simple text prompts for marketing campaigns. Build a centralized library of product videos with automated tracking and storage. How it works The workflow operates as a webhook-triggered process, organized into these stages: Webhook Trigger & Input Accepts POST requests to the /create-ugc-video endpoint. Required payload includes: product prompt, video prompt, Gemini API key, and OpenAI API key. Image Generation (Gemini) Sends the product prompt to Google's Gemini 2.5 Flash Image model. Generates a product image based on the description provided. Data Extraction Code node extracts the base64 image data from Gemini's response. Preserves all prompts and API keys for subsequent steps. Video Generation (SORA 2) Sends the video prompt to OpenAI's SORA 2 API. Initiates video generation with specifications: 720x1280 resolution, 8 seconds duration. Returns a video generation job ID for polling. Video Status Polling Continuously checks video generation status via OpenAI API. If status is "completed": proceeds to download. If status is still processing: waits 1 minute and retries (polling loop). Video Download & Storage Downloads the completed video file from OpenAI. Uploads the MP4 file to Google Drive (root folder). Generates a shareable Google Drive link. Logging to Google Sheets Records all generation details in a tracking spreadsheet: Product description Video URL (Google Drive link) Generation status Timestamp Summary Flow: Webhook Request → Generate Product Image (Gemini) → Extract Image Data → Generate Video (SORA 2) → Poll Status → If Complete: Download Video → Upload to Google Drive → Log to Google Sheets → Return Response If Not Complete: Wait 1 Minute → Poll Status Again Benefits: Fully automated video creation pipeline from text to finished product. Scalable solution for generating multiple product videos on demand. Combines cutting-edge AI models (Gemini + SORA 2) for high-quality output. Centralized storage in Google Drive with automatic logging in Google Sheets. Flexible webhook interface allows integration with any application or service. Retry mechanism ensures videos are captured even with longer processing times. --- Created by Daniel Shashko

Add Spending Analytics Extend the daily check-in to calculate: Weekly/monthly spending summaries Category-wise breakdowns Use additional Code nodes to process transaction history Important Notes ⚠️ Never trigger with normal messages - Only use app mentions (@botname) to avoid infinite loops where the bot replies to its own messages. 💡 Context Awareness - The bot remembers conversation history, so you can reference "yesterday", "last week", or previous transactions naturally. 🔒 Data Privacy - All your financial data stays in your Google Sheets and PostgreSQL database. The AI only processes transaction text temporarily. 📊 Backup Regularly - Export your Google Sheets periodically as backup. --- Pro Tips: Start with small test transactions to ensure everything works Use consistent person names for debt tracking The bot understands various formats: "₹500 cash food" = "paid 500 rupees in cash for food" You can batch transactions in one message: "₹100 travel, ₹200 food, ₹50 snacks"
