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.).
