2slides Presentation Generation

Overview

Generate professional presentations using the 2slides AI API. The skill supports content-based generation (theme-driven Fast PPT), style matching from a reference image, custom PDF design, document summarization, AI voice narration, and exporting pages/audio. It returns both an interactive slide URL and a downloadable PDF.

This skill is adapted from the official 2slides skill repository (2slides/slides-generation-2slides-skills). It calls the hosted 2slides API and requires the user's own API key and credits.

When to Use This Skill

• Use when the user asks to "create a presentation", "make slides", or "generate a deck" from text or an outline.
• Use when the user wants slides that match the style of a reference image ("create slides like this image").
• Use when the user wants custom-designed PDF slides without a reference image.
• Use when the user uploads a document and asks to "create slides from this document".
• Use when the user wants to add AI voice narration to generated slides, or export slides as PNG images and narration as WAV audio.
• Use when the user asks "what themes are available?" or wants to browse/select a theme.

Setup Requirements

Users must have a 2slides API key and credits:

1. Get API Key: Visit https://2slides.com/api to create an account and API key
   • New users receive 500 free credits (~50 Fast PPT pages)
2. Purchase Credits (Optional): Visit https://2slides.com/pricing to buy additional credits
   • Pay-as-you-go, no subscriptions
   • Credits never expire
   • Up to 20% off on larger packages
3. Set API Key: Store the key in environment variable: SLIDES_2SLIDES_API_KEY

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 (all values from 2slides API):

--language LANG                 # Auto, English, Spanish, Arabic, Portuguese, Indonesian,
                                 # Japanese, Russian, Hindi, French, German, Greek, Vietnamese,
                                 # Turkish, Polish, Italian, Korean, Simplified Chinese,
                                 # Traditional Chinese, Thai (default: Auto)
--mode sync|async                # default: sync for theme, async for reference-image
--aspect-ratio RATIO             # 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9 (default: 16:9)
--resolution 1K|2K|4K            # default: 2K
--page N                         # 0=auto, 1-100 (default: 1)
--content-detail concise|standard # default: concise

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:

Install the Python dependency first if it is not already available:

python -m pip install -r requirements.txt

# Basic generation
python scripts/create_pdf_slides.py --content "Your content here"

# With design style (API: designStyle)
python scripts/create_pdf_slides.py \
  --content "Sales Report Q4 2025" \
  --design-style "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-style "text"           # Design instructions (API: designStyle)
--language LANG                 # Same as generate_slides (default: Auto)
--aspect-ratio RATIO           # 1:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9 (default: 16:9)
--resolution 1K|2K|4K          # default: 2K
--page N                        # 0=auto, 1-100 (default: 1)
--content-detail concise|standard # default: standard

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.

1. Generate slides first using any method (Section 1, 2, 3, or 4)
2. Get the job ID from the generation result
3. 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"

# Single speaker, 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

Parameters (aligned with 2slides API):

• --job-id: Job ID (required, UUID for Nano Banana)
• --voice: Voice name (default: Puck); use --list-voices for all 30
• --language: Narration language (default: Auto)
• --multi-speaker: Enable multi-speaker mode
• --list-voices: Print the supported voices without calling the API

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:

1. Show user available themes with names and descriptions
2. Ask user to choose or let them use default
3. Use the theme ID in generation request

---

Security & Safety Notes

• Credentials: This skill reads the API key from the SLIDES_2SLIDES_API_KEY environment variable. Never hard-code the key in commands, commit it, or echo it back to the user. The scripts send it as a bearer/apikey value to https://2slides.com over HTTPS only.
• Network + paid mutations: Every generation call makes an outbound network request to the 2slides API and spends the user's credits (10–210 credits/page depending on mode). Treat generation, reference-image, custom-PDF, and narration calls as billable actions — confirm intent before generating large or high-resolution (4K) decks, and surface the expected page count/cost when it is non-trivial.
• No destructive local actions: The scripts only read content/files the user points to and write generated output (e.g. a downloaded ZIP) to the path the user specifies. They do not modify or delete unrelated files.
• Input handling: Reference-image and document inputs are sent to the 2slides service for processing. Do not submit confidential material the user has not authorized for third-party processing.
• Download URLs expire in 1 hour — fetch artifacts promptly and do not treat the URLs as durable storage.

Limitations

• Requires a valid 2slides account, API key, and sufficient credits; this skill does not provision or pay for credits.
• Results are AI-generated drafts intended as a starting point, not a final, fact-checked deliverable — review content before use.
• This skill does not replace environment-specific validation or expert review. Stop and ask for clarification if the API key, required inputs, or intended cost/scope are missing.
• Rate limits apply (Fast PPT 10/min, Nano Banana 6/min); poll async jobs every 20–30s rather than tight-looping.
