原文外掛簡介
AI Alt Text Builder writes accurate, descriptive alt text for the images in your Media Library, in one click or in bulk.
Images without alt text cost you twice. Search engines cannot tell what the image shows, so it ranks lower in Google Images, and screen reader users hear nothing at all. Accessibility standards such as WCAG 2.1, which both the ADA Title II rule in the US and the European Accessibility Act in the EU build on, require a text alternative for every meaningful image.
Start free in seconds: 25 free generations, no sign-up and no API key. Prefer your own OpenAI API key? Then single-image generations are unlimited, and you only pay OpenAI’s usage.
Fixing hundreds of images? Pro writes alt text for your whole Media Library in bulk and can fill it in automatically on every new upload. Plans start at $2.99/month, billed yearly. See pricing
