พรอมต์เปรียบเทียบผลิตภัณฑ์สองรายการ

product_comparison_prompt = '''
Compare the two product images above (Image 1 and Image 2).

Analyze each of the following dimensions:

1. SIMILARITIES: What features, design elements, or characteristics do both products share?

2. DIFFERENCES: What are the key visual differences? Focus on:
   - Color and finish
   - Size and proportions (estimate if possible)
   - Design style (minimalist, ornate, modern, traditional)
   - Materials (if discernible)
   - Quality indicators

3. QUALITY ASSESSMENT: Which image appears to show a higher-quality product, and why?
   Rate each product 1-10 for apparent quality.

4. USE CASE: Based on appearance alone, which product seems better suited for:
   a) Professional/office use
   b) Home/casual use

Return your response in this format exactly.

การเปรียบเทียบก่อนและหลัง

before_after_prompt = '''
You are looking at two images: a BEFORE image (Image 1) and an AFTER image (Image 2).

Analyze the transformation:

1. WHAT CHANGED: List all visible changes from Before to After
2. WHAT STAYED THE SAME: List elements that are unchanged
3. QUALITY IMPROVEMENT: Rate the improvement on a scale of 1-10 (1=no improvement, 10=dramatic improvement)
4. REMAINING ISSUES: What could still be improved that the transformation did not address?

Context: This is a [CONTEXT_PLACEHOLDER] before/after comparison.

design_comparison_prompt = '''
You are an experienced UX designer reviewing two design variants (Image 1 = Design A, Image 2 = Design B).

Evaluate both designs on:

1. VISUAL HIERARCHY: Which design guides the eye more effectively? Why?

3. BRAND CONSISTENCY: Which feels more professional and polished?
4. USABILITY: Which would be easier for a new user to navigate?
5. EMOTIONAL IMPACT: Which creates a stronger positive first impression?

For each dimension, declare a winner (A or B) and explain in one sentence.
