How I built a free WordPress plugin that auto-generates image alt text using AI

The problem I kept running into

Every time I ran an accessibility or SEO audit on a WordPress site,
the same issue came up: 60-80% of images had no alt text.

It's not that people don't care. Writing alt text for hundreds of
images manually is genuinely painful — so people just skip it.

I decided to fix this once and for all.

EzAlt AI — a free WordPress plugin that generates alt text
automatically using AI vision models.

Here's what it does:

Bulk generation — scan your entire Media Library and generate alt text for every image missing it, in one click
Auto-generate on upload — every new image gets alt text automatically
Per-image generation — generate directly from the Media Library attachment page
Never overwrites — if an image already has alt text, it's skipped
Context-aware — the plugin sends the parent post title, categories, and content type (including WooCommerce products) to the AI, so the output is relevant — not generic

API requests are idempotent — retries never double-charge credits.

A plugin that works out of the box. Install → activate → done.
Free starter credit included, no card required.

Happy to answer any questions about the implementation!
