GlobalDev AI Image Metadata helps WordPress administrators fill in the metadata fields that images so often lack: alternative text, titles, captions and descriptions.
Rather than treating alt text as an isolated task, it covers the full set of Media Library fields for JPEG, PNG and WebP files, and lets site owners generate this content one image at a time, in bulk for images missing alt text, or automatically as new files are uploaded.
The metadata is generated through GlobalDev AI Hub, an external service that requires a project API key created by the site administrator. When a request runs, the plugin sends a reduced copy of the image along with the target language and the site name to the Hub, which returns the generated text along with token usage information.
Results appear directly on the Media Library screens, where they can be reviewed and edited before saving, and the plugin itself does not disclose which underlying AI model or provider the Hub uses.

Key Features of GlobalDev AI Image Metadata
Full metadata generation. Produces alternative text, attachment title, caption and description from a single image, covering fields that are often left empty in the Media Library.
Flexible language output. Uses the WordPress site language by default, or accepts a custom language name or locale so metadata can be generated in a language other than the site’s default.
Bulk generation with live progress. Scans the library for images missing alt text and processes them one by one through AJAX, showing processed, generated and failed counts as the job runs, and can be stopped without losing completed work.
Automatic processing on upload. Can queue new supported uploads for background generation through WP-Cron, though this automatic behavior stays off unless the administrator turns it on.
Review before saving. Generated values can be checked and edited in the Media Library before they are saved, and existing metadata is left untouched unless overwrite is specifically enabled for automatic processing.
Token usage visibility. Displays per-image and cumulative token counts reported by GlobalDev AI Hub, giving site owners a running view of how much usage each generation request consumes.
How to Install GlobalDev AI Image Metadata
Step 1: Install and activate. From the WordPress dashboard go to Plugins > Add New Plugin, search for GlobalDev AI Image Metadata, then click Install Now followed by Activate.
Step 2: Open the settings page. Go to Media > AI Image Metadata > Settings to begin connecting the plugin to GlobalDev AI Hub.
Step 3: Create a project API key. Click Get API key to be redirected to the GlobalDev project-creator page, sign in, create or regenerate the website project key, then return to the site; the key installs automatically or can be pasted in manually.
Step 4: Test the connection. Use the Test connection option to confirm the key works, then choose the site language or enter a custom language or locale for generated metadata.
Step 5: Generate metadata. Open Media > AI Image Metadata to generate and review metadata for individual images or to start a bulk generation job for images missing alt text.
Good to Know About GlobalDev AI Image Metadata
According to the plugin’s documentation, GlobalDev AI Hub does not reveal which AI model or provider handles generation; the plugin only reports results and usage totals. The developer notes that language support is open ended, accepting any language name or locale, though output quality depends on the external service’s capabilities for that language.
Reported token counts come from the provider when available, otherwise the Hub marks them as estimates. Bulk generation only targets images with missing or empty alt text and skips images that already have it, and the external Hub service may apply its own usage quotas or plans, separate from the plugin itself.
