<p><strong>AI Auto Alt Text Generator</strong> is a lightweight, privacy-conscious plugin that uses OpenAI vision-capable models (defaulting to GPT-4o mini, with GPT 5 Mini/Nano options) 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.</p>
<p>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.</p>
<h3>✨ Key features</h3>
<ul>
<li><strong>Automatic alt text on upload</strong> – set-and-forget accessibility.</li>
<li><strong>Optional automatic image titles</strong> – improve SEO with descriptive titles.</li>
<li><strong>One-click manual generation</strong> – “Generate Alt Text & Title” button in the Media Library.</li>
<li><strong>Bulk update tool</strong> – batch-process existing images (five at a time) with a configurable pause between batches.</li>
<li><strong>Prompt fine-tuning</strong> – supply site-wide context and optionally include the image file name.</li>
<li><strong>Model selection</strong> – choose GPT-4o mini (default) or GPT 5 Mini/Nano (BETA).</li>
<li><strong>Image size & detail control</strong> – choose the resolution and level of visual detail sent.</li>
<li><strong>No extra servers</strong> – data flows only between your site and OpenAI; nothing is stored off-site.</li>
<li><strong>Multilingual output</strong> – 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><strong>Tools <span aria-hidden="true" class="wp-exclude-emoji">→</span> Bulk Alt Text Update</strong></li>
<li><strong>Media <span aria-hidden="true" class="wp-exclude-emoji">→</span> Bulk Alt Text Update</strong> (shortcut that redirects to the Tools page)</li>
<li><strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Alt Text Generator</strong> 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 your selected OpenAI vision model.</li>
<li>OpenAI 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><strong>OpenAI API Key</strong> – Required to connect to GPT-4o.  </li>
<li><strong>OpenAI Model</strong> – GPT-4o mini (default), GPT 5 Mini (BETA), or GPT 5 Nano (BETA).  </li>
<li><strong>Image Size to Send</strong> – Thumbnail, Medium, Large, or Full.  </li>
<li><strong>Image Detail Quality</strong> – ‘Low’ or ‘High’ (Low uses fewer tokens).  </li>
<li><strong>Bulk batch size</strong> – Number of images per batch (lower values reduce rate-limit risk).  </li>
<li><strong>Site Context</strong> – Optional free-form prompt guidance (brand voice, niche, etc.).  </li>
<li><strong>Send Image File Name</strong> – Include file name in the prompt for extra context.  </li>
<li><strong>Automatically Generate Title</strong> – Add descriptive titles alongside alt text.  </li>
<li><strong>Use full context for image titles</strong> – When enabled, title generation includes site context and file name (uses more tokens).  </li>
<li><strong>Bulk optimiser delay (seconds)</strong> – Pause between batches during bulk runs.  </li>
<li><strong>OpenAI request timeout (seconds)</strong> – Max wait time for OpenAI responses (10–120s) to reduce timeout failures on slower hosts.  </li>
<li><strong>Output Language</strong> – 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>
<h3>External services</h3>
<p>This plugin connects to the <strong>OpenAI API</strong> to generate alt text and (optionally) image titles.</p>
