Workflow Decision Tree

Choose the appropriate approach based on the user's request: User Request │ ├─ "Create slides from this content/text" │ └─> Use Content-Based Generation (Section 1) │ ├─ "Create slides like this image" │ └─> Use Reference Image Generation (Section 2) │ ├─ "Create custom designed slides" or "Create PDF slides" │ └─> Use Custom PDF Generation (Section 3) │ ├─ "Create slides from this document" │ └─> Use Document Summarization (Section 4) │ ├─ "Add voice narration" or "Generate audio for slides" │ └─> Use Voice Narration (Section 5) │ ├─ "Download slides as images" or "Export slides and voices" │ └─> Use Download Export (Section 6) │ └─ "Search for themes" or "What themes are available?" └─> Use Theme Search (Section 7)

1. Content-Based Generation

Generate slides from user-provided text content.

When to Use

User provides content directly in their message User says "create a presentation about X" User provides structured outline or bullet points

Workflow

• Step 1: Prepare Content
• Structure the content clearly for best results:
• Title: [Main Topic]
• Section 1: [Subtopic]
• Key point 1
• Key point 2
• Key point 3
• Section 2: [Subtopic]
• Key point 1
• Key point 2
• Step 2: Choose Theme (Required)
• Search for an appropriate theme (themeId is required):
• python scripts/search_themes.py --query "business"
• python scripts/search_themes.py --query "professional"
• python scripts/search_themes.py --query "creative"
• Pick a theme ID from the results.
• Step 3: Generate Slides
• Use the generate_slides.py script with the theme ID:
• # Basic generation (theme ID required)
• python scripts/generate_slides.py --content "Your content here" --theme-id "theme123"
• # In different language
• python scripts/generate_slides.py --content "Your content" --theme-id "theme123" --language "Spanish"
• # Async mode for longer presentations
• python scripts/generate_slides.py --content "Your content" --theme-id "theme123" --mode async
• Step 4: Handle Results
• Sync mode response:
• {
• "slideUrl": "https://2slides.com/slides/abc123",
• "pdfUrl": "https://2slides.com/slides/abc123/download",
• "status": "completed"
• }
• Provide both URLs to the user:
• slideUrl: Interactive online slides
• pdfUrl: Downloadable PDF version
• Async mode response:
• {
• "jobId": "job123",
• "status": "pending"
• }
• Poll for results:
• python scripts/get_job_status.py --job-id "job123"

2. Reference Image Generation

Generate slides that match the style of a reference image.

When to Use

User provides an image URL and says "create slides like this" User wants to match existing brand/design style User has a template image they want to emulate

Workflow

Step 1: Verify Image URL Ensure the reference image is: Publicly accessible URL Valid image format (PNG, JPG, etc.) Represents the desired slide style Step 2: Generate Slides Use the generate_slides.py script with --reference-image: python scripts/generate_slides.py \ --content "Your presentation content" \ --reference-image "https://example.com/template.jpg" \ --language "Auto" Optional parameters: --aspect-ratio "16:9" # width:height format (e.g., "16:9", "4:3") --resolution "2K" # "1K", "2K" (default), or "4K" --page 5 # Number of slides (0 for auto-detection, max 100) --content-detail "concise" # "concise" (brief) or "standard" (detailed) Note: This uses Nano Banana Pro mode with credit costs: 1K/2K: 100 credits per page 4K: 200 credits per page Step 3: Handle Results This mode always runs synchronously and returns: { "slideUrl": "https://2slides.com/workspace?jobId=...", "pdfUrl": "https://...pdf...", "status": "completed", "message": "Successfully generated N slides", "slidePageCount": N } Provide both URLs to the user: slideUrl: View slides in 2slides workspace pdfUrl: Direct PDF download (expires in 1 hour) Processing time: ~30 seconds per page (30-60 seconds typical for 1-2 pages)

3. Custom PDF Generation

Generate custom-designed slides from text without needing a reference image.

When to Use

User wants custom design without providing a reference image User requests "create PDF slides" User wants to specify design characteristics Alternative to theme-based generation with more design flexibility

Workflow

• Step 1: Prepare Content
• Structure the content clearly:
• Title: [Main Topic]
• Section 1: [Subtopic]
• Key point 1
• Key point 2
• Section 2: [Subtopic]
• Key point 1
• Key point 2
• Step 2: Generate Slides
• Use the create_pdf_slides.py script:
• # Basic generation
• python scripts/create_pdf_slides.py --content "Your content here"
• # With design specifications
• python scripts/create_pdf_slides.py \
• --content "Sales Report Q4 2025" \
• --design-spec "modern minimalist, blue color scheme"
• # High resolution with auto page detection
• python scripts/create_pdf_slides.py \
• --content "Marketing Plan" \
• --resolution "4K" \
• --page 0 \
• --content-detail "standard"
• Optional parameters:
• --design-spec "text" # Design specifications (e.g., "corporate professional")
• --aspect-ratio "16:9" # width:height format
• --resolution "2K" # "1K", "2K" (default), or "4K"
• --page 5 # Number of slides (0 for auto-detection, max 100)
• --content-detail "concise" # "concise" (brief) or "standard" (detailed)
• --language "Auto" # Language for content
• Step 3: Handle Results
• Returns same structure as create-like-this:
• {
• "slideUrl": "https://2slides.com/workspace?jobId=...",
• "pdfUrl": "https://...pdf...",
• "status": "completed",
• "message": "Successfully generated N slides",
• "slidePageCount": N
• }
• Notes:
• Same credit costs as create-like-this (100 credits/page for 1K/2K, 200 for 4K)
• Processing time: ~30 seconds per page
• Automatically generates PDF
• Uses AI to create custom design based on content and specs

4. Document Summarization

Generate slides from document content.

When to Use

User uploads a document (PDF, DOCX, TXT, etc.) User says "create slides from this document" User wants to summarize long content into presentation format

Workflow

• Step 1: Read Document
• Use appropriate tool to read the document content:
• PDF: Use PDF reading tools
• DOCX: Use DOCX reading tools
• TXT/MD: Use Read tool
• Step 2: Extract Key Points
• Analyze the document and extract:
• Main topics and themes
• Key points for each section
• Important data, quotes, or examples
• Logical flow and structure
• Step 3: Structure Content
• Format extracted information into presentation structure:
• Title: [Document Main Topic]
• Introduction
• Context
• Purpose
• Overview
• [Section 1 from document]
• Key point 1
• Key point 2
• Supporting detail
• [Section 2 from document]
• Key point 1
• Key point 2
• Supporting detail
• Conclusion
• Summary
• Key takeaways
• Next steps
• Step 4: Generate Slides
• Use content-based generation workflow (Section 1). First search for a theme, then generate:
• # Search for appropriate theme
• python scripts/search_themes.py --query "business"
• # Generate with theme ID
• python scripts/generate_slides.py --content "[Structured content from step 3]" --theme-id "theme123"
• Tips:
• Keep slides concise (3-5 points per slide)
• Focus on key insights, not full text
• Use document headings as slide titles
• Include important statistics or quotes
• Ask user if they want specific sections highlighted

5. Voice Narration

Add AI-generated voice narration to slides.

When to Use

User wants to add audio to slides User requests "add voice narration" or "generate audio" User wants presentations with spoken content User needs multi-speaker narration

Prerequisites

IMPORTANT: The slide generation job must be completed before adding narration. Generate slides first using any method (Section 1, 2, 3, or 4) Get the job ID from the generation result Ensure job status is "completed" before requesting narration

Workflow

Step 1: Choose Voice 30 voices available including: Puck (default) Aoede Charon Kore Fenrir Phoebe And 24 more... List all voices: python scripts/generate_narration.py --list-voices Step 2: Generate Narration Use the generate_narration.py script with the job ID: # Basic narration with default voice python scripts/generate_narration.py --job-id "abc-123-def-456" # With specific voice python scripts/generate_narration.py --job-id "abc-123-def-456" --voice "Aoede" # Multi-speaker mode python scripts/generate_narration.py --job-id "abc-123-def-456" --multi-speaker # In specific language python scripts/generate_narration.py \ --job-id "abc-123-def-456" \ --language "Spanish" \ --voice "Charon" Parameters: --job-id: Job ID from slide generation (required, must be UUID format for Nano Banana) --voice: Voice name (default: "Puck") --multi-speaker: Enable multi-speaker mode (default: off) --language: Language for narration (default: "Auto") Step 3: Check Status Narration generation runs asynchronously: python scripts/get_job_status.py --job-id "abc-123-def-456" Step 4: Handle Results Once completed, the job will include narration files. Use download endpoint (Section 6) to get audio files. Notes: Cost: 210 credits per page (10 for text, 200 for audio) Processing time varies by slide count 30 voice options available Supports 19 languages plus auto-detection Multi-speaker mode uses different voices for variety

6. Download Export

Download slides as PNG images and voice narrations as WAV files.

When to Use

User wants to download slides as images User needs voice files separately User wants transcripts User needs slides in image format for other tools

Workflow

Step 1: Verify Job Complete Ensure slides (and optionally narration) are generated and job is completed. Step 2: Download Archive Use the download_slides_pages_voices.py script: # Download with default filename (<job_id>.zip) python scripts/download_slides_pages_voices.py --job-id "abc-123-def-456" # Download to specific path python scripts/download_slides_pages_voices.py \ --job-id "abc-123-def-456" \ --output "my-presentation.zip" Step 3: Extract Contents The ZIP archive contains: Pages: PNG files for each slide Voices: WAV audio files (if narration was generated) Transcripts: Text transcripts of narration Notes: Cost: Completely FREE (no credits used) Download URLs valid for 1 hour only Includes all pages and voice files High quality PNG export WAV format for audio

7. Theme Search

Find appropriate themes for presentations.

When to Use

Before generating slides with specific styling User asks "what themes are available?" User wants professional or branded appearance

Workflow

Search themes: # Search for specific style (query is required) python scripts/search_themes.py --query "business" python scripts/search_themes.py --query "creative" python scripts/search_themes.py --query "education" python scripts/search_themes.py --query "professional" # Get more results python scripts/search_themes.py --query "modern" --limit 50 Theme selection: Show user available themes with names and descriptions Ask user to choose or let them use default Use the theme ID in generation request

Using the MCP Server

If the 2slides MCP server is configured in Claude Desktop, use the integrated tools instead of scripts. Two Configuration Modes: Streamable HTTP Protocol (Recommended) Simplest setup, no local installation Configure: "url": "https://2slides.com/api/mcp?apikey=YOUR_API_KEY" NPM Package (stdio) Uses local npm package Configure: "command": "npx", "args": ["2slides-mcp"] Available MCP tools: slides_generate - Generate slides from content slides_create_like_this - Generate from reference image themes_search - Search themes jobs_get - Check job status See mcp-integration.md for complete setup instructions and detailed tool documentation. When to use MCP vs scripts: Use MCP in Claude Desktop when configured Use scripts in Claude Code CLI or when MCP not available

Sync vs Async Mode

Sync Mode (default): Waits for generation to complete (30-60 seconds) Returns results immediately Best for quick presentations Async Mode: Returns job ID immediately Poll for results with get_job_status.py Best for large presentations or batch processing Recommended polling: Check every 20-30 seconds to avoid server strain
