Transform meeting transcripts into AI-generated presentations with Google Slides & Flux

Transform meeting transcripts into fully customized, AI-powered presentations automatically. This comprehensive 5-workflow automation system analyzes client conversations and generates professional slide decks complete with personalized content and AI-generated illustrations.

🎯 What This Automation Does

This end-to-end solution takes a meeting transcript (Google Docs) and client information as input, then automatically:

• Creates a presentation from your custom template
• Generates a strategic presentation plan tailored to the client's needs
• Creates custom illustrations using AI image generation
• Populates slides with personalized text content
• Inserts generated images into the appropriate slides
• Delivers a client-ready presentation

Perfect for sales teams, consultants, agencies, and anyone who needs to create customized presentations at scale.

🔧 How It Works

The automation is split into 5 interconnected workflows:

Workflow 1: Clone Presentation & Database Setup

• Form trigger captures client name, transcript URL, and submission time
• Clones your presentation template via Google Slides API
• Saves presentation details to Google Sheets for tracking

Workflow 2: AI Presentation Plan Generation

• Analyzes meeting transcript to understand client pain points
• Generates comprehensive presentation structure and content strategy
• Saves plan to Google Docs for review and tracking
• Uses company profile (customizable) to match solutions to client needs

Workflow 3: AI Illustration Generation

• AI agent creates image prompts based on presentation plan
• Generates illustrations using Flux model via OpenRouter (nanobanana)
• Uploads images to Google Drive for slide insertion
• Tracks all generated assets in database

Workflow 4: Text Content Population

• AI agent generates final presentation text from the plan
• Replaces template placeholders with personalized content
• Uses Object IDs to target specific text elements in slides
• Updates slides using native n8n Google Slides node

Workflow 5: Image Insertion

• Retrieves image Object IDs from presentation structure
• Downloads illustrations from Google Drive
• Converts images for ImgBB hosting (resolves Google Drive URL limitations)
• Updates slide images via Google Slides API

📋 Prerequisites

Required Accounts & API Keys:

• Google Workspace (Drive, Slides, Docs)
• OpenAI API (for AI agents)
• OpenRouter API (for Flux image generation)
• ImgBB API (free tier available)
• Gemini API (optional, for additional AI tasks)

Setup Requirements:

• Google Sheets database (template provided in article and inside the workflow)
• Google Slides presentation template with standard Object IDs
• Meeting transcript in Google Docs format

🎨 Customization Options

This automation is designed to be flexible:

• Template Flexibility: Use any slide template structure
• Company Profile: Customize the business context for your use case
• AI Models: Swap OpenAI/Gemini agents for your preferred LLM
• Image Generation: Replace Flux with DALL-E, Midjourney API, or other models
• Slide Logic: Extend to dynamically select slides based on content needs

💡 Key Technical Insights

• Structured Output Handling: Uses JavaScript for reliable JSON parsing when AI output structure is complex
• Object ID System: Template placeholders use unique IDs for precise element targeting
• Image Hosting Workaround: ImgBB resolves Google Drive direct URL limitations in API calls
• HTTP Request Nodes: Used for API operations not covered by native n8n nodes (copying presentations, image updates)
