External Services
This plugin connects to the Alt Text Studio API (hosted at api.alttextstudio.com) to generate alt text for images. When you upload an image or click Generate:
- The image (either as a URL reference or as base64-encoded data) is sent to our servers along with your optional settings (text length, languages, SEO keywords, e-commerce fields, custom prompt).
- Our servers pass the image to our AI provider for analysis and return the generated alt text.
- The image and generated text are associated with your Alt Text Studio account for your library and billing history. You can delete any image from your library at any time via your account dashboard.
- No image content is sent anywhere other than our own servers. We do not share data with advertisers or unrelated third parties.
