Dynamic Parameters

AI Generation with .prompt

Generate dynamic text and images using AI with the .prompt parameter

Overview

The .prompt parameter enables AI-powered content generation for text and image elements. Instead of providing static content, you can supply a natural language prompt that generates contextual content on-the-fly.

How It Works

When you add .prompt to a parameterized element, Orshot uses AI to generate appropriate content:

  • Text elements - Generates text using openai/gpt-5-nano
  • Image elements - Generates images using google/nano-banana

The generated content replaces the element's default content during render.

Syntax

parameterID.prompt

For multi-page templates:

pageN@parameterID.prompt

Text Generation

Basic Usage

{
  "modifications": {
    "headline.prompt": "Write a catchy headline about coffee"
  }
}

This generates AI text for the headline element instead of using its template default.

Detailed Prompts

Be specific to get better results:

{
  "modifications": {
    "description.prompt": "Write a 2-sentence product description for wireless headphones with noise cancellation, emphasizing comfort and battery life",
    "tagline.prompt": "Create a 5-word motivational tagline about productivity"
  }
}

Multi-Page Example

{
  "modifications": {
    "page1@title.prompt": "Write a title about morning routines",
    "page2@title.prompt": "Write a title about evening habits",
    "page1@body.prompt": "Write 3 tips for productive mornings",
    "page2@body.prompt": "Write 3 tips for better sleep"
  }
}

Image Generation

Basic Usage

{
  "modifications": {
    "background.prompt": "A serene mountain landscape at sunset"
  }
}

Detailed Image Prompts

Include style, mood, and composition details:

{
  "modifications": {
    "hero.prompt": "Modern office workspace with plants, natural lighting, minimalist design, professional photography style",
    "illustration.prompt": "Flat design illustration of people collaborating, bright colors, vector art style"
  }
}

Multi-Page Image Generation

{
  "modifications": {
    "page1@background.prompt": "Sunrise over city skyline, golden hour",
    "page2@background.prompt": "Busy city street at noon, aerial view",
    "page3@background.prompt": "City lights at night, long exposure"
  }
}

Combining with Regular Parameters

You can mix .prompt with regular parameters to refine the output:

{
  "modifications": {
    "title.prompt": "Write a headline about innovation",
    "title.fontSize": "48px",
    "title.color": "#0066cc",
    "title.fontFamily": "Montserrat"
  }
}

The AI generates the text content, while the style parameters control its appearance.

Element Type Validation

The .prompt parameter only works with text and image elements:

Supported:

{
  "textElement.prompt": "...", // ✓ Text element
  "imageElement.prompt": "..." // ✓ Image element
}

Not Supported:

{
  "rectangle.prompt": "...", // ✗ Shape element - ignored
  "circle.prompt": "..." // ✗ Shape element - ignored
}

If you try to use .prompt on unsupported elements, Orshot will:

  1. Log a warning
  2. Skip the prompt generation
  3. Use the element's default content

Fallback Behavior

When AI generation fails (network issues, API errors, etc.), Orshot falls back gracefully:

  1. Regular modification exists - Uses the regular parameter value

    {
      "title": "Fallback Title",
      "title.prompt": "Generate a title"
    }

    If AI fails, it uses "Fallback Title"

  2. No regular modification - Uses template default If AI fails and no fallback is provided, the element shows its original template content

Best Practices

Text Prompts

  1. Be Specific - Include length, tone, and context

    {
      "bio.prompt": "Write a 50-word professional bio for a software engineer specializing in AI"
    }
  2. Set Constraints - Specify word/sentence count

    {
      "headline.prompt": "Create a 7-word headline about sustainable fashion"
    }
  3. Define Tone - Mention style or emotion

    {
      "message.prompt": "Write an encouraging message for students, friendly and motivational tone"
    }

Image Prompts

  1. Include Style - Specify artistic style or medium

    {
      "artwork.prompt": "Abstract watercolor painting of ocean waves, blue and teal colors"
    }
  2. Describe Composition - Mention perspective and layout

    {
      "photo.prompt": "Top-down view of healthy breakfast bowl, natural lighting, food photography"
    }
  3. Add Context - Include mood and atmosphere

    {
      "scene.prompt": "Cozy coffee shop interior, warm lighting, people working on laptops, relaxed atmosphere"
    }

Limitations & Considerations

  1. AI Credits Required - Text and image generation consumes AI credits based on your plan
  2. Generation Time - AI prompts add processing time (typically 2-5 seconds per element)
  3. Rate Limits - Subject to plan-based rate limits for AI generation
  4. Content Safety - Generated content passes through safety filters
  5. Determinism - Same prompt may generate slightly different results each time
