Extension Metadata
About this extension
PromptLens bridges the gap between visual inspiration and AI creation.
Found an image you love and want to recreate it in Stable Diffusion, ComfyUI, or Midjourney? Stop guessing the prompt. Right-click the image, select "PromptLens — Generate JSON Prompt", and get a structured JSON object copied to your clipboard in seconds.
WHAT YOU GET:
- prompt — a detailed, ready-to-use description for any AI image generator
- style — the visual style (photograph, illustration, 3D render...)
- subject, setting, lighting, mood — all broken down
- colors — dominant palette
- negative_prompt — what to exclude to match the original
- tags — useful keywords for further refinement
HOW IT WORKS:
PromptLens uses OpenRouter's automatic model routing to select the best available vision AI model for each request. You bring your own OpenRouter API key (free to create, ~$0.005 per image analyzed). No subscriptions, no data stored on external servers beyond what you explicitly send for analysis.
PRIVACY:
Your API key is stored locally in your browser. Images are sent directly to OpenRouter only when you explicitly trigger the analysis. We collect nothing.
REQUIREMENTS:
A free OpenRouter account and API key from openrouter.ai
