Alt Text Generator AI – Automatically generate alt text for images using AI

Alt Text Generator AI writes descriptive, SEO-friendly alt text for your WordPress images automatically, so every image on your site is accessible and discoverable without typing a single description by hand.

Over 50% of websites are still missing alt text on their images, and ADA-related web accessibility lawsuits have topped 3,100 filings in a single year. Missing alt text is more than a lost SEO opportunity in Google Image Search. It is a real accessibility and legal risk.

Four ways to generate alt text

1. Automatically on upload – Alt text is written the moment an image finishes uploading to the Media Library. On by default, and you can switch it off in Settings.
2. One click in the Media Library – Open any image and click Generate Alt Text to create or regenerate its alternative text.
3. In bulk – The Bulk Alt Text page scans your whole library and sorts images into Empty, Short (under 20 characters) and All tabs. Search by ID or text, generate for selected images, or generate for everything in the tab.
4. From the command line – Use wp alt-text generate to process an entire library with WP-CLI.

Why Alt Text Matters

• SEO – Google uses alt text to understand and rank your images in Image Search, which can drive organic traffic to product pages, blog posts and galleries.
• Accessibility – Alt text lets screen readers describe your images to visually impaired visitors, a core requirement of WCAG 2.1/2.2.
• Legal compliance – ADA and Section 508 website-accessibility lawsuits are rising every year. Properly described images reduce that exposure.

Using WP-CLI

The plugin registers an alt-text command with two subcommands. Run them from your WordPress root folder (the one containing wp-config.php). The plugin must be active, with your API key and domain saved in AltTextGenerator → Settings.

Commands

• wp alt-text status – Shows API status, remaining credits, website domain, language and how many images are missing alt text.
• wp alt-text generate – Generates alt text for every image that has none.

Options for wp alt-text generate

• --short – Also regenerate images whose alt text is shorter than 20 characters.
• --all – Regenerate every image in the library, even if it already has alt text.
• --ids=<ids> – Only process these attachment IDs (comma-separated).
• --force – With --ids, regenerate even if the image already has alt text.
• --limit=<number> – Process at most this many images in one run.
• --dry-run – List the images that would be processed without calling the API or using credits.

Examples

# Check API status, credits, and how many images are missing alt text
wp alt-text status

# Generate alt text for every image that's missing it
wp alt-text generate

# Also regenerate images whose alt text is too short
wp alt-text generate --short

# Regenerate every image in the library
wp alt-text generate --all

# Regenerate specific attachments, even if they already have alt text
wp alt-text generate --ids=12,34,56 --force

# Preview what would be processed, without using any credits
wp alt-text generate --limit=20 --dry-run

Each generated image uses one credit. Run wp alt-text status first to check your balance, and --dry-run to preview large jobs.
