Promptoscope

Promptoscope is a Chrome extension for designers, art directors, marketers and visual creators. It turns a public reference image into a structured visual recipe and a reusable JSON prompt. Analyze the subject, composition, lighting, colors, visual style, camera cues and visible details, then carry the result into your next image-generation workflow. Use it to study references, document creative direction and move faster from inspiration to a repeatable visual system. Promptoscope is available as a free public beta and works without an account. The extension sends the image URL and image content temporarily to Gemini 3.1 Flash-Lite after user consent, and does not keep the image in permanent backend storage. It is designed for public images and should not be used with private or confidential material.
