Alt Goblin is the “set it and forget it” way to keep your WordPress media library accessible and SEO-friendly.
Once activated, it fits right into your existing workflow — no complicated setup, no new screens to learn. Just upload images like you normally would, and let Alt Goblin generate clear, descriptive alt text for you.
Whether you’re managing a small blog or a media-heavy site, Alt Goblin helps you stay consistent without slowing you down.
You can:
<ul>
<li>Generate or re-generate alt text directly inside the Media modal</li>
<li>Optionally guide output with comma-separated keywords</li>
<li>Automatically generate alt text on upload</li>
<li>Bulk process older images missing alt text</li>
<li>Track your free and paid credits from a simple dashboard</li>
</ul>
Each generation uses 1 credit and 1 credit = 1 alt text. Free monthly credits are included, and additional credit packs are available if you need them.
Install it. Activate it. Let it work in the background.

Connor Bulmer

AI Auto Alt Text Generator 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.
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>Model selection – choose GPT-4o mini (default) or GPT 5 Mini/Nano (BETA).</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 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>OpenAI API Key – Required to connect to GPT-4o. </li>
<li>OpenAI Model – GPT-4o mini (default), GPT 5 Mini (BETA), or GPT 5 Nano (BETA). </li>
<li>Image Size to Send – Thumbnail, Medium, Large, or Full. </li>
<li>Image Detail Quality – ‘Low’ or ‘High’ (Low uses fewer tokens). </li>
<li>Bulk batch size – Number of images per batch (lower values reduce rate-limit risk). </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 batches during bulk runs. </li>
<li>OpenAI request timeout (seconds) – Max wait time for OpenAI responses (10–120s) to reduce timeout failures on slower hosts. </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>
