AI Auto Alt Text Generator is a lightweight, privacy-conscious plugin that uses OpenAI’s GPT-4o mini vision model to create meaningful, screen-reader-friendly alt text and SEO-friendly titles for your images. Whether you add a single image, bulk-process your library, or just want a one-click fix in the Media Library, the plugin handles it all – no manual effort required.
This solution is far cheaper than many alternatives because it cuts out the middle-person. You’ll just need to bring your own OpenAI API key.
<h3>✨ Key features</h3>
<ul>
<li>Automatic alt text on upload – set-and-forget accessibility.</li>
<li>Optional automatic image titles – improve SEO with descriptive titles.</li>
<li>One-click manual generation – “Generate Alt Text & Title” button in the Media Library.</li>
<li>Bulk update tool – batch-process existing images (five at a time) with a configurable pause between batches.</li>
<li>Prompt fine-tuning – supply site-wide context and optionally include the image file name.</li>
<li>Image size & detail control – choose the resolution and level of visual detail sent.</li>
<li>No extra servers – data flows only between your site and OpenAI; nothing is stored off-site.</li>
<li>Multilingual output – choose English (UK), English (US) or other popular languages. (English US is the default.)</li>
</ul>
<h3>🧭 Where to find the bulk tool</h3>
<ul>
<li>Tools → Bulk Alt Text Update</li>
<li>Media → Bulk Alt Text Update (shortcut that redirects to the Tools page)</li>
<li>Settings → Alt Text Generator includes a button linking straight to the bulk page</li>
</ul>
<h3>🧠 How it works</h3>
<ol>
<li>When an image is uploaded (or manually chosen), the plugin creates a temporary public URL for that image.</li>
<li>It sends the image – plus optional context such as the parent post title, your custom site context and the file name – to OpenAI’s gpt-4o-mini vision model.</li>
<li>GPT-4o returns a concise description.
<ul>
<li>Alt text is stored in WordPress’ native <code>_wp_attachment_image_alt</code> field. </li>
<li>(Optional) The returned title is stored as the attachment post title.</li>
</ul>
</li>
<li>Nothing is cached or stored on OpenAI’s side; only the final strings live in your database.</li>
</ol>
<h3>Settings overview</h3>
<ul>
<li>OpenAI API Key – Required to connect to GPT-4o. </li>
<li>Image Size to Send – Thumbnail, Medium, Large, or Full. </li>
<li>Image Detail Quality – ‘Low’ or ‘High’. </li>
<li>Site Context – Optional free-form prompt guidance (brand voice, niche, etc.). </li>
<li>Send Image File Name – Include file name in the prompt for extra context. </li>
<li>Automatically Generate Title – Add descriptive titles alongside alt text. </li>
<li>Use full context for image titles – When enabled, title generation includes site context and file name (uses more tokens). </li>
<li>Bulk optimiser delay (seconds) – Pause between five-image batches during bulk runs. </li>
<li>Output Language – Default English (US). Choose English (UK) for British spellings or another popular language; outputs (alt text and titles) will be generated in the selected language.</li>
</ul>
