<p>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.</p>
<p><strong>Features</strong></p>
<ul>
<li>Supports OpenAI, Anthropic Claude, and Google Gemini multimodal models</li>
<li>Generates alt text for individual images in the Media Library and media modal</li>
<li>Processes missing-alt backlogs in batches with a dedicated bulk queue</li>
<li>Handles provider rate limits with automatic cooldown locks</li>
<li>Adds a Media Library column with quick generate/regenerate actions</li>
<li>Provides a customizable prompt seed for output consistency</li>
</ul>
<p><strong><em>Media Library Tools</em></strong></p>
<p>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.</p>
<p><strong><em>Bulk Generator</em></strong></p>
<p>The Bulk page counts images missing alt text, allows regeneration preferences, and runs batches while surfacing progress, failures, and rate-limit pauses.</p>
