Image to Prompt

Analyze images and generate detailed, reproduction-quality prompts for AI image generation.

Workflow

Step 1: Category Detection First, classify the image into one of these categories:

• portrait — People as main subject (photos, artwork, digital art)
• landscape — Natural scenery, cityscapes, architecture, outdoor environments
• product — Commercial product photos, merchandise
• animal — Animals as main subject
• illustration — Diagrams, infographics, UI mockups, technical drawings
• other — Images that don't fit above categories

Step 2: Category-Specific Analysis Generate a detailed prompt based on the detected category.

Usage

Basic Analysis

# Analyze an image (auto-detect category)
openclaw message send --image /path/to/image.jpg "Analyze this image and generate a detailed prompt for reproduction"

Specify Output Format

Natural Language (default):

Analyze this image and write a detailed, flowing prompt description (600-1000 words for portraits, 400-600 for others).

Structured JSON:

Analyze this image and output a structured JSON description with all visual elements categorized.

With Dimensions Extraction

Request dimension highlights to get tagged phrases for each visual aspect:

Analyze this image with dimension extraction. Tag phrases for: backgrounds, objects, characters, styles, actions, colors, moods, lighting, compositions, themes.

Tips for Best Results

1. High-resolution images produce more detailed prompts
2. Clear, well-lit images yield better category detection
3. Request structured output when you need programmatic access to individual elements
4. Use dimensions extraction when building prompt databases or training data
5. Specify word count expectations for natural language output if needed
