Alt tags matter. They help visually impaired users understand your images, improve your search engine rankings, and are a basic requirement for web accessibility. Writing them by hand for every image in your media library is tedious. Altagonist takes care of it for you.
Point it at your images, click Generate, and get descriptive alt tags written by AI, saved directly into your WordPress media library.
How it works
<ol>
<li>Open the Altagonist page in your WordPress admin</li>
<li>Browse your media library and select one or more images</li>
<li>Click Generate. Image info is sent to the Altagonist API and an alt tag comes back</li>
<li>The alt tag is saved to your media library, just like you typed it yourself</li>
</ol>
Features
<ul>
<li>AI-powered alt tag generation using computer vision</li>
<li>Supports JPEG, PNG, GIF, and WebP. SVG, AVIF, TIFF, and BMP are converted automatically</li>
<li>Bulk generation: select multiple images and process them all at once</li>
<li>Three quality levels (Lite, Medium, High). Higher quality uses more page context for better results</li>
<li>70 languages supported</li>
<li>Auto-generate on upload: enable in Settings to tag images the moment they are uploaded</li>
<li>Filters to show only images with missing alt tags so you can close gaps quickly</li>
<li>Alt tags are saved to the standard <code>_wp_attachment_image_alt</code> field, fully compatible with all themes and plugins</li>
</ul>
External service
Images are processed externally. When you trigger alt tag generation (manually or via auto-generate on upload), the following data is sent:
<ul>
<li>The image URL (or the image itself as base64 if the URL is not publicly reachable)</li>
<li>Site name, page title, and page content (amount depends on the quality setting)</li>
<li>Selected language and quality level</li>
<li>Your license key and site URL</li>
</ul>
No data is sent unless you actively trigger generation or have auto-generate on upload enabled. Images are processed in real-time and are not stored.
