Presswell Alt Text Generator vs SEO Image Toolbox

Presswell Alt Text Generator helps teams reduce accessibility backlog by generating descriptive alt text for new and existing images. Connect a provider, choose a model, and run generation workflows directly inside wp-admin. Features Supports OpenAI, Anthropic Claude, and Google Gemini multimodal models Generates alt text for individual images in the Media Library and media modal Processes missing-alt backlogs in batches with a dedicated bulk queue Handles provider rate limits with automatic cooldown locks Adds a Media Library column with quick generate/regenerate actions Provides a customizable prompt seed for output consistency Media Library Tools Inline actions let you generate or regenerate alt text directly from each image row. When an image has no alt text, the column displays a “Generate Alt Text” link that triggers the AJAX workflow and replaces itself with the result. Bulk Generator The Bulk page counts images missing alt text, allows regeneration preferences, and runs batches while surfacing progress, failures, and rate-limit pauses.
