Overview

"Image to Prompt" is a browser extension that analyzes images you explicitly select on web pages, reverse-engineers an editable text-to-image prompt, and can optionally generate new images. The developer operates no server and does not collect, receive, or store any of your data. All processing happens directly between your browser and the AI provider you choose on the extension's options page. This version contains no server-side worker or gateway.

Data stored locally

The extension uses chrome.storage.local to store the following configuration locally in your browser only:

• The image-analysis (prompt) provider configuration you enter
• The image-generation provider configuration you enter
• API Key
• Base URL
• Model name
• Whether automatic analysis is enabled
• Whether image generation is enabled
• Image-generation settings such as the number of output images

To restore the current page's state, the extension also caches the most recent reference images, prompts, generated-image history, and analysis results in local IndexedDB. This cache stays in your browser and is never uploaded to any first-party server. None of this configuration or cache is ever written to the code repository.

Data sent to external APIs

The extension only calls an external API when you actively trigger analysis or generation:

• When you click the analyze button on a web image, the extension reads that image and sends the image data, the page URL, and the image alt text to the prompt provider you have configured.
• When you use the screenshot/drag-to-select mode, the extension captures only the region you selected and sends that screenshot data and the page URL to the prompt provider you have configured.
• When you click "Generate," the extension sends the current prompt, the chosen aspect ratio, and the number of output images to the image-generation provider you have configured. If you have uploaded reference images, up to two of them are sent along with the request.

The provider is your choice — by default Evolink (https://evolink.ai); optionally OpenAI-compatible services, Google Gemini, or a custom provider you enter. Your API key is transmitted only to that provider, as the authentication credential for your own requests, and is never sent to the developer. How each provider handles your data is governed by that provider's own terms of service and privacy policy.
