Alt Goblin

Description

Alt Goblin is the “set it and forget it” way to keep your WordPress media library accessible and SEO-friendly.

Once activated, it fits right into your existing workflow — no complicated setup, no new screens to learn. Just upload images like you normally would, and let Alt Goblin generate clear, descriptive alt text for you.

Whether you’re managing a small blog or a media-heavy site, Alt Goblin helps you stay consistent without slowing you down.

You can:

  • Generate or re-generate alt text directly inside the Media modal
  • Optionally guide output with comma-separated keywords
  • Automatically generate alt text on upload
  • Bulk process older images missing alt text
  • Track your free and paid credits from a simple dashboard

Each generation uses 1 credit and 1 credit = 1 alt text. Free monthly credits are included, and additional credit packs are available if you need them.

Install it. Activate it. Let it work in the background.

FAQ

Do I need an API key?

No. Alt Goblin works out of the box using the free monthly plan. Add an API key only if you purchase paid credits.

How many free credits are included?

The free plan currently provides 25 credits per month. Resets on the first of every month.

What images are processed in bulk mode?

Bulk mode only processes images that are missing alt text. Images that already have alt text are skipped and no credits are used.

Does this overwrite existing alt text?

Single-image generation replaces the current value for that image. Bulk mode is designed to process only images without alt text.

Is this compatible with classic and block editor workflows?

Yes. Alt Goblin works inside WordPress admin media contexts and is independent of your theme or editor output.
