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.
Task: Generate 1 optimized image title based on the provided topic and attached image.

Uhallo Sight is an AI alt text and image accessibility plugin for WordPress. It helps agencies, freelancers, WooCommerce teams, and site owners find missing or weak image descriptions, improve image SEO, and support WCAG image accessibility work without manually opening every media item.
Install the plugin, Connect to Uhallo, then run Start Bulk Scan from Settings -> Uhallo. Uhallo reviews your existing WordPress Media Library, detects unverified image metadata, uses OCR-first image analysis when text appears inside an image, drafts practical alt text, and writes approved fixes back into native WordPress attachment metadata. After setup, new uploads are protected too, so your site does not drift back into missing alt text.
The plugin also shows a clear WordPress admin dashboard with an Image Metadata Score, scan status, upload protection, widget coverage, trial usage, and before/after fixes. The Client Proof Summary gives agencies and consultants a simple way to show what changed: images scanned, missing or weak alt text found, verified fixes saved, new-upload protection, and recent examples.
Uhallo Sight is built for real WordPress cleanup work:
<ul>
<li>AI alt text for WordPress images and WooCommerce product media.</li>
<li>Bulk Media Library scans for old posts, pages, galleries, and uploads.</li>
<li>OCR-first descriptions for banners, menus, warning labels, charts, and screenshots with visible text.</li>
<li>Native WordPress alt text writeback, not a separate overlay-only system.</li>
<li>Optional frontend widget coverage for theme or page-builder images that need extra help.</li>
<li>Base64 firewall mode for private, staging, or locked-down WordPress sites.</li>
<li>Trial counters and proof summaries for agencies selling accessibility care plans.</li>
</ul>
<h4>External service and privacy</h4>
Uhallo Sight connects your WordPress site to the Uhallo API at https://api.uhallo.com. This external service is required for account connection, image analysis, AI alt-text generation, usage tracking, and writing generated descriptions back to WordPress.
When you connect the plugin or scan images, the plugin sends your Uhallo client identifier, signed request metadata, WordPress site URL, attachment ID, image URL or image data when firewall mode is enabled, existing alt text, filename, MIME type, and callback URL. Uhallo uses this data to generate alt text, update the matching WordPress attachment, measure usage, and keep the service secure.
The optional frontend widget is disabled by default. If a site administrator enables widget coverage, the plugin loads the Uhallo JavaScript widget from https://api.uhallo.com/uhallo.js on the public site with the connected Uhallo client identifier. The widget checks frontend images that themes or page builders render outside normal WordPress media writeback, reuses existing Uhallo-written alt text when present, and sends image metadata to Uhallo only when frontend coverage is needed.
An active Uhallo account and subscription may be required to use the hosted AI service. By connecting Uhallo Sight, site administrators agree to Uhallo’s terms and privacy policy at https://uhallo.com/terms and https://uhallo.com/privacy.
