## 總覽

WebML Image Captioning is a free Chrome extension that generates descriptive captions for images using machine learning models that run entirely inside your browser. It can caption images from local files or from a browser tab, and lets you export or clear the collected results at any time.

## 價格與方案

Free. The extension is published on the Chrome Web Store at no cost, with no subscription or paid tiers listed.

## 關鍵功能與能力

- **Captioning that runs locally in your browser:** The captioning model is downloaded into the browser and inference happens on your own machine, so images are never transmitted to a third-party cloud service.
- **Works with files and browser tabs:** Caption images stored on your computer or images shown in the current browser tab, without saving them first.
- **Offline capable once initialized:** After the model has been initialized the extension can keep captioning images without an active internet connection.
- **Export and clean your data:** Save the caption output together with the related images, and clear the stored data whenever you choose.
- **Privacy-conscious data handling:** Per the developer's Chrome Web Store disclosure, data is not sold to third parties and is not used outside the extension's core functionality.

## 主要使用情境

- **Draft alt text and image descriptions (Content & accessibility teams):** Generate a first-draft description of an image to speed up writing alt text for web pages, documents or internal content libraries.
- **Describe confidential visuals safely (Designers and researchers):** Caption product shots, screenshots or reference images without uploading proprietary material to an external service.
- **Keep working without connectivity (Field and remote workers):** Caption images while offline — on a plane, on a restricted network, or in an environment where uploads are blocked.

## 優勢

- Image data never leaves your device
- Works offline after the model initializes
- Handles both local files and browser tab images
- Export and data-cleaning options built in
- No account or sign-in required

## 限制

- Requires an initial model download/initialization before offline use works
- Model accuracy is below large cloud vision APIs for complex scenes
- Small user base with no accumulated ratings yet
- Interface is functional rather than polished

## 常見問題

### Does the extension upload my images to a server?
No. The captioning model is downloaded and executed locally in your browser, so image data is not sent to an external cloud service. Once initialization is complete you can even keep working without an internet connection.

### Can I caption images that are already on a webpage?
Yes. You can point it at image files on your device, or caption an image displayed in a browser tab without downloading it first.

### Can I save the captions it produces?
The extension includes an export capability, so you can save the caption results along with their associated images. You can also clean or delete accumulated data whenever you want.

### Who is this extension for?
It is most useful for quickly describing images, generating starting points for alt text, and light accessibility or cataloguing work where privacy and offline availability matter more than maximum accuracy.
