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. ### WebML Image Captioning 的月流量和增长趋势如何？ WebML Image Captioning 目前每月获得 0 访问量，月度环比流量变化为 +0（增长率 0.0%）。其主要来源市场是全球（— 份额），包括每月 0 次直接访问和每月 0 次自然搜索访问。 ### WebML Image Captioning 免费吗？它的定价模式是什么？ WebML Image Captioning 采用免费定价模式。Free.
