  Opten scores your AI prompt for the specific model you're using — before you generate.
  
  PROBLEM:
  Every AI model understands prompts differently. What works for Midjourney fails on Seedance. What's great for GPT Image is useless for Kling. You write the same prompt for all models — and waste credits on bad results.
  
  SOLUTION:
  Opten analyzes your prompt against 43 model-specific rule sets. One click — and you see exactly what to fix. Another click — Auto-enhance rewrites your prompt automatically.
  
  HOW IT WORKS:
  1. Write your prompt in the AI generator
  2. Click the Opten icon
  3. See your score (red/yellow/green) with specific feedback
  4. Click "Auto-enhance" to fix it instantly
  
  SUPPORTED MODELS (43+):
  - Image: Midjourney v7/v8, GPT Image 1/1.5, Flux, Flux Kontext, Imagen 4, Seedream 4/5, Nano Banana, and more
  - Video: Seedance 1.5 Pro, Kling 2.6/3.0, Sora 2, Veo 3, Luma Ray 2/3, and more
  
  WHY OPTEN:
  ✓ Model-specific — not generic tips, but rules for YOUR model
  ✓ Built-in — works right inside the generator, no copy-paste
  ✓ Auto-enhance — AI rewrites your prompt in one click
  ✓ 43+ models — the largest coverage of any prompt tool
  
  Works on syntx.ai. More platforms coming soon.
  
  What's new in 1.1.0:
  
  ✓ Click-to-score — prompt is scored only when you click the button, no more auto-triggers
  ✓ Auto Enhance without scoring — improve your prompt instantly with one click
  ✓ Redesigned tooltip — two-block layout with per-issue star ratings and score ring
  ✓ Idea detection — short prompts get an "Auto Enhance" nudge instead of an error
  ✓ Multi-model support — automatically detects which AI model is selected (Seedance, Kling, Midjourney, GPT Image, Flux & 43 more) and scores with model-specific rules
  ✓ Reference image analysis — uploaded images are analyzed for faces, objects & scenes to give context-aware scoring
  ✓ Parallel scoring — score + rewrite run simultaneously for faster results
