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
Open the Altagonist page in your WordPress admin
Browse your media library and select one or more images
Click Generate. Image info is sent to the Altagonist API and an alt tag comes back
The alt tag is saved to your media library, just like you typed it yourself
Features
AI-powered alt tag generation using computer vision
Supports JPEG, PNG, GIF, and WebP. SVG, AVIF, TIFF, and BMP are converted automatically
Bulk generation: select multiple images and process them all at once
Three quality levels (Lite, Medium, High). Higher quality uses more page context for better results
70 languages supported
Auto-generate on upload: enable in Settings to tag images the moment they are uploaded
Filters to show only images with missing alt tags so you can close gaps quickly
Alt tags are saved to the standard _wp_attachment_image_alt field, fully compatible with all themes and plugins
External service
Images are processed externally. When you trigger alt tag generation (manually or via auto-generate on upload), the following data is sent:
The image URL (or the image itself as base64 if the URL is not publicly reachable)
Site name, page title, and page content (amount depends on the quality setting)
Selected language and quality level
Your license key and site URL
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.
