Transform Meeting Transcripts into AI-Generated Presentations with Google Slides
This n8n workflow automates the process of converting meeting transcripts into structured data, generating presentation content using an AI agent, and then creating a Google Slides presentation from that content. It streamlines the creation of presentations from raw meeting notes, saving time and effort.
What it does
- Triggers on Form Submission: The workflow starts when a form is submitted, likely containing a meeting transcript.
- Extracts Transcript from File: It takes the submitted file (presumably a text or document file containing the transcript) and extracts its content.
- Prepares Data for AI: The extracted transcript is then processed by a Code node to format it for the AI agent.
- Generates Presentation Content with AI: An AI Agent (configured with an OpenAI Chat Model) analyzes the transcript and generates structured presentation content (e.g., title, slides with bullet points) based on a defined schema.
- Parses AI Output: A Structured Output Parser node converts the AI-generated content into a usable JSON format.
- Creates Google Slides Presentation: The parsed content is then used to create a new Google Slides presentation, populating it with the generated title and slide content.
- Uploads to Google Drive: The newly created Google Slides presentation is uploaded to a specified folder in Google Drive.
- Records in Google Sheets: The workflow also records details of the generated presentation (e.g., title, Google Drive link) into a Google Sheet.
- Waits (Optional/Placeholder): A Wait node is included, which could be used for rate limiting or to introduce a delay if subsequent actions require it.
Prerequisites/Requirements
To use this workflow, you will need:
- n8n Instance: A running n8n instance.
- Google Account: With access to Google Drive, Google Slides, and Google Sheets.
- Google OAuth2 Credentials: Configured in n8n for Google Drive, Google Slides, and Google Sheets.
- OpenAI API Key: For the OpenAI Chat Model used by the AI Agent. Alternatively, a Google Gemini API Key if you switch to the Google Gemini Chat Model.
- A Form Submission Mechanism: The workflow is triggered by an n8n Form Trigger. You will need to create and share this form.
Setup/Usage
- Import the Workflow: Download the JSON provided and import it into your n8n instance.
- Configure Credentials:
- Set up your Google OAuth2 credentials for Google Drive, Google Slides, and Google Sheets.
- Set up your OpenAI API key credential (or Google Gemini API key if you switch the model).
- Configure Nodes:
- On form submission (Trigger): Ensure this form is configured to receive the meeting transcript file.
- Extract from File: Verify the settings for extracting content from your expected transcript file type.
- Code: Review and adjust the JavaScript code if your input transcript format or desired AI prompt structure changes.
- AI Agent:
- Ensure the "OpenAI Chat Model" (or "Google Gemini Chat Model" if swapped) is selected and configured with your API key.
- Review the "Prompt" and "Tools" to ensure the AI generates the desired presentation structure.
- Structured Output Parser: Verify the schema matches the expected output from the AI Agent.
- Google Slides: Configure the "Create" operation, specifying the parent folder ID in Google Drive, and mapping the AI-generated title and slide content.
- Google Drive: Configure the "Upload" operation, specifying the target folder ID for the presentation.
- Google Sheets: Configure the "Append Row" operation, specifying your spreadsheet ID and sheet name, and mapping the relevant data (e.g., presentation title, Google Drive URL).
- Wait: Adjust the delay if necessary, or remove it if not needed.
- Activate the Workflow: Once configured, activate the workflow.
- Submit a Form: Use the URL provided by the "On form submission" trigger node to submit a meeting transcript file and test the workflow.

By Mikal Hayden-GatesAi website scraper & company intelligence
AI Website Scraper & Company Intelligence Description This workflow automates the process of transforming any website URL into a structured, intelligent company profile. It's triggered by a form, allowing a user to submit a website and choose between a "basic" or "deep" scrape. The workflow extracts key information (mission, services, contacts, SEO keywords), stores it in a structured Supabase database, and archives a full JSON backup to Google Drive. It also features a secondary AI agent that automatically finds and saves competitors for each company, building a rich, interconnected database of company intelligence. --- Quick Implementation Steps Import the Workflow: Import the provided JSON file into your n8n instance. Install Custom Community Node: You must install the community node from: https://www.npmjs.com/package/n8n-nodes-crawl-and-scrape FIRECRAWL N8N Documentation https://docs.firecrawl.dev/developer-guides/workflow-automation/n8n Install Additional Nodes: n8n-nodes-crawl-and-scrape and n8n-nodes-mcp fire crawl mcp . Set up Credentials: Create credentials in n8n for FIRE CRAWL API,Supabase, Mistral AI, and Google Drive. Configure API Key (CRITICAL): Open the Web Search tool node. Go to Parameters → Headers and replace the hardcoded Tavily AI API key with your own. Configure Supabase Nodes: Assign your Supabase credential to all Supabase nodes. Ensure table names (e.g., companies, competitors) match your schema. Configure Google Drive Nodes: Assign your Google Drive credential to the Google Drive2 and save to Google Drive1 nodes. Select the correct Folder ID. Activate Workflow: Turn on the workflow and open the Webhook URL in the “On form submission” node to access the form. --- What It Does Form Trigger Captures user input: “Website URL” and “Scraping Type” (basic or deep). Scraping Router A Switch node routes the flow: Deep Scraping → AI-based MCP Firecrawler agent. Basic Scraping → Crawlee node. Deep Scraping (Firecrawl AI Agent) Uses Firecrawl and Tavily Web Search. Extracts a detailed JSON profile: mission, services, contacts, SEO keywords, etc. Basic Scraping (Crawlee) Uses Crawl and Scrape node to collect raw text. A Mistral-based AI extractor structures the data into JSON. Data Storage Stores structured data in Supabase tables (companies, company_basicprofiles). Archives a full JSON backup to Google Drive. Automated Competitor Analysis Runs after a deep scrape. Uses Tavily web search to find competitors (e.g., from Crunchbase). Saves competitor data to Supabase, linked by company_id. --- Who's It For Sales & Marketing Teams: Enrich leads with deep company info. Market Researchers: Build structured, searchable company databases. B2B Data Providers: Automate company intelligence collection. Developers: Use as a base for RAG or enrichment pipelines. --- Requirements n8n instance (self-hosted or cloud) Supabase Account: With tables like companies, competitors, social_links, etc. Mistral AI API Key Google Drive Credentials Tavily AI API Key (Optional) Custom Nodes: n8n-nodes-crawl-and-scrape --- How It Works Flow Summary Form Trigger: Captures “Website URL” and “Scraping Type”. Switch Node: deep → MCP Firecrawler (AI Agent). basic → Crawl and Scrape node. Scraping & Extraction: Deep path: Firecrawler → JSON structure. Basic path: Crawlee → Mistral extractor → JSON. Storage: Save JSON to Supabase. Archive in Google Drive. Competitor Analysis (Deep Only): Finds competitors via Tavily. Saves to Supabase competitors table. End: Finishes with a No Operation node. --- How To Set Up Import workflow JSON. Install community nodes (especially n8n-nodes-crawl-and-scrape from npm). Configure credentials (Supabase, Mistral AI, Google Drive). Add your Tavily API key. Connect Supabase and Drive nodes properly. Fix disconnected “basic” path if needed. Activate workflow. Test via the webhook form URL. --- How To Customize Change LLMs: Swap Mistral for OpenAI or Claude. Edit Scraper Prompts: Modify system prompts in AI agent nodes. Change Extraction Schema: Update JSON Schema in extractor nodes. Fix Relational Tables: Add Items node before Supabase inserts for arrays (social links, keywords). Enhance Automation: Add email/slack notifications, or replace form trigger with a Google Sheets trigger. --- Add-ons Automated Trigger: Run on new sheet rows. Notifications: Email or Slack alerts after completion. RAG Integration: Use the Supabase database as a chatbot knowledge source. --- Use Case Examples Sales Lead Enrichment: Instantly get company + competitor data from a URL. Market Research: Collect and compare companies in a niche. B2B Database Creation: Build a proprietary company dataset. --- WORKFLOW IMAGE --- Troubleshooting Guide | Issue | Possible Cause | Solution | |-------|----------------|-----------| | Form Trigger 404 | Workflow not active | Activate the workflow | | Web Search Tool fails | Missing Tavily API key | Replace the placeholder key | | FIRECRAWLER / find competitor fails | Missing MCP node | Install n8n-nodes-mcp | | Basic scrape does nothing | Switch node path disconnected | Reconnect “basic” output | | Supabase node error | Wrong table/column names | Match schema exactly | --- Need Help or More Workflows?
