Alt Magic: AI Image Alt Text Generator for WP & Image Rename

77 Quality Score

Active Installs

15/30

At 1,000 active installs the user base is small, though that is partly offset by a high install-to-rating ratio showing strong early adoption among those who try it.

Update Freshness

25/25

The plugin was updated in July 2026, which is very recent, and it is built for modern WordPress so maintenance signals are excellent.

User Rating

15/15

A perfect 100 from 18 reviews is a strong signal, though the small sample size means a single negative experience could shift the picture quickly.

Support Health

8/15

There are zero support threads in the repository, so we have no real data on how responsive the developer is when something breaks.

WP Compatibility

What It Does

Alt Magic uses an AI service to write alt text for images in your WordPress media library, with a bulk mode for existing images and automatic processing for new uploads. It also offers an optional AI image renaming feature that rewrites image filenames to something more SEO friendly. A small number of free monthly credits are included, after which you would likely need a paid plan.

Who It's For

This plugin is a good fit for small to mid sized site owners who have hundreds of legacy images without alt text and want to backfill them quickly for accessibility and SEO. It is also useful for publishers who regularly add new images and want a hands off workflow for descriptive alt attributes.

Who Should Skip It

If you only have a handful of images, or you prefer to write alt text by hand for accuracy and brand voice, this plugin is overkill. Sites that already use a bulk filename based alt text tool, or that need an offline or self hosted AI solution, should look elsewhere.

The Bottom Line

Alt Magic scores a solid 75.93 with standout maintenance and a flawless early rating record, but the very small install count and zero public support history make it hard to fully trust at scale. It is worth trying on a staging site or for a small library, and you should have a paid AI plan in mind if you have more than a few dozen images per month. For larger or mission critical sites, the more established alternatives carry less risk.

Pick this if you want a free, proven, 100,000 install solution that derives alt text from filenames rather than paying for an AI service.

WP Accessibility 83/100

Pick this if you need a broader accessibility toolkit beyond alt text, including skip links, color contrast, and ARIA fixes.

Alt Text AI 81/100

Pick this if you specifically want AI generated alt text with 20,000 installs of community track record behind it.
