Rewrites a passage to hit a target grade-band reading level (simpler vocabulary, shorter sentences for lower; richer vocabulary, complex syntax for higher). Preserves factual accuracy and key concepts.

Input

{
  "text": "Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water.",
  "current_level": "8",
  "target_level": "4",
  "preserve_terms": ["photosynthesis"]
}

Output

{
  "tool": "text-leveler",
  "leveled_text": "Photosynthesis is how plants make their own food. They use sunlight, water, and a gas called carbon dioxide from the air. The plant turns these into sugar, which gives it energy to grow.",
  "original_level": "8",
  "target_level": "4",
  "estimated_result_level": "3-4",
  "changes_made": ["simplified vocabulary", "split compound sentence", "added explanation of carbon dioxide"],
  "preserved_terms": ["photosynthesis"],
  "human_review_required": true
