AI Alt Text Creator is a complete solution for automating image SEO and accessibility on your WordPress site. It uses Artificial Intelligence to analyze your images and generate descriptive, context-aware Alt Text and Titles.
By connecting to OpenRouter, this plugin bypasses expensive monthly subscriptions, giving you direct access to the world’s best AI models (including Google Gemini, GPT-4, and Claude 3.5) at the lowest possible cost.
🚀 Key Features
One-Click Manual Generation: Instantly generate metadata for individual images directly from the Media Library list view. Perfect for new uploads or refining specific images.
Automated Background Processing: Process your entire back catalog automatically using the built-in Cron scheduler. Configure batch sizes and intervals to suit your server’s capacity.
Context-Aware Descriptions: The AI reads the Title and Content of the post/page the image is attached to. This ensures the generated Alt Text is relevant to your specific article, not just a generic description of the visual.
Global Context: Add custom instructions (e.g., “Always mention our brand name ‘Acme Corp'”) that apply to every image generated.
Smart Error Handling:
Retry Failed: Automatically logs failed attempts. You can retry all failed images with one click from the settings page.
JSON Fixer: A specialized tool to scan and fix images where the AI might have accidentally saved raw code instead of text.
Detailed Logging: View the exact generation timestamp, source (Manual vs Cron), and any error messages directly in the “Edit Media” screen.
Cost Control: You bring your own API key. You pay only for exactly what you use, with no markup.
Format Control: Choose exactly which file types to process (JPG, PNG, WEBP, etc.).
🧠 Why OpenRouter?
OpenRouter is an AI aggregator that offers significant benefits for WordPress users:
Cheaper: Models like Google Gemini 1.5 Flash are incredibly affordable (often fractions of a cent per image).
Flexible: Switch models instantly. If a new model is released tomorrow, you can simply paste its ID and use it immediately.
No Middleman: You use your own API key.
💡 Context & Prompts
You can customize exactly how the AI behaves using placeholders in your prompts:
Examples of Global Context:
<pre><code>Inputs:
– Page Topic: [{post_title}]
– Page Content: [{post_content}]
– Image: [attached image]
</code></pre>
Examples of Alt Text Prompt:
<pre><code>Role: Web Accessibility and SEO Expert.
Task: Generate a single, optimized alt text string (MAX 125 characters) for the provided image, situated within the context of inputs.
</code></pre>
Examples of Alt Text Prompt:
<pre><code>Role: SEO Copywriting Specialist.

<h3>Evaluate results</h3>
Recommended Tools 
– <a href="https://developer.chrome.com/docs/lighthouse/" rel="nofollow ugc">Lighthouse</a> (in Chrome DevTools) — Analyze image weight and format, as well as the use of alternative text (ALT). 
– <a href="https://www.webpagetest.org/" rel="nofollow ugc">WebPageTest</a> — Check how images affect real-world load times. 
– <a href="https://squoosh.app/" rel="nofollow ugc">Squoosh</a> — Compare visual quality and file size savings when optimizing images.

Evaluation Guidelines 
– Identify images without ALT text or with excessive file size before running external tests. 
– After replacing large images or adding ALT text, repeat your evaluations to confirm improvements. 
– Evaluate both new and existing content — not only the most recent uploads. 
– Define an internal size limit (for example, 200 KB per image) and monitor it regularly. 
– Keep in mind that accessibility also affects SEO and overall user experience.

Bubuku Media Library

Una idea excelente, imprescindible en toda biblioteca de utilidades WPO para la correcta optimización de las webs.

Además, tiene aún algunas posibilidades de crecimiento como mostrar en el frontend a los usuarios conectados como admin las imágenes con un outline en caso de no tener definido el alt img:not([alt]) o quizás también leer el tamaño de las imágenes y mostrar los códigos de color según su peso, etc.

Como digo, una idea excelente, de un excelente programador.

Imprescindible en la biblioteca de utilidades WPO

Muy útil para gestión del día a día de las imágenes
