Description
The free WordPress alt text generator plugin that doesn't charge per image.
Every SEO tool nags about missing image alt text. Every accessibility audit flags it. Every Google Lighthouse report scores you down. Yet writing alt text by hand for hundreds of images is a Saturday you'll never get back. And the existing cloud-AI alt text plugins want a monthly subscription (Alt Text AI is $4/month, Image Describer is $9/month) or charge per-image fees that add up fast on stores with thousands of product photos.
Why WooCom Alt Text beats the alternatives: WooCom Alt Text runs against your own local Ollama server - a free, open-source AI runtime. Alt text generation costs you literally zero per image, sends no image data to any third party, and works entirely on your own hardware. The only network call is to YOUR Ollama URL. No calls to wpwoocom.com, OpenAI, or any analytics service.
First WordPress plugin to register a wordpress-ai/alt-text Abilities API provider
WordPress 7.0 shipped the Abilities API - the standard way for AI clients to call into your site. WooCom Alt Text registers as the canonical alt-text provider. When WordPress core routes an alt-text generation call, this plugin answers it. MCP-connected AI clients (Claude Desktop, Cursor, ChatGPT) can drive the whole workflow.
Fully compatible with the block editor and WooCommerce
Works with the Gutenberg block editor natively (image blocks, gallery blocks, cover blocks - all inherit the generated alt). Compatible with WooCommerce product images and variation images. Auto-generate on upload means every new image self-tags immediately.
