AI Image Alt Text Generator & Image SEO – ImageCraft

ImageCraft is an AI Image Alt Text Generator for WordPress that automatically creates SEO-optimized alt text for your images. Improve accessibility, boost image SEO, and rename image files using OpenAI, Claude, or Gemini — all with your own API key and no subscription fees.

Generate SEO-friendly alt text for hundreds of images in minutes instead of hours.

Why ImageCraft?

Most alt text plugins charge monthly subscriptions or per-image credits through their own proxy service. ImageCraft connects directly to your AI provider — you pay only the provider’s standard API rate with zero markup.

How It Works

1. Connect — Add your API key in your WordPress site from Anthropic, OpenAI, or Google Gemini (3-minute setup wizard)

3. Review — Preview generated alt text, edit if needed, then accept. Or enable auto-accept for hands-free processing

Typical API Costs

You pay only for API usage directly to your chosen provider. Since ImageCraft uses a BYOK model, there is no markup — you get the same rate as any developer using the API directly. Check your provider’s pricing page for current rates:

• Anthropic Claude pricing
• OpenAI pricing
• Google Gemini pricing

ImageCraft vs Other Plugins

• vs subscription plugins — No monthly fees. Pay per use at direct API rates with zero markup.
• vs single-provider plugins — 3 providers, 15+ models. Switch anytime without losing data or reconfiguring.
• vs alt-text-only plugins — ImageCraft also renames files for SEO, runs an SEO audit, and integrates with your SEO plugin’s focus keyphrase.
• vs manual alt text — Batch process 500 images in minutes instead of writing each one by hand. AI understands image content, product context, and SEO keywords.

Privacy & Security

• API keys encrypted with AES-256-CBC using WordPress salts (or stored in wp-config.php for file-based security)
• Images sent only to your chosen AI provider when you trigger generation
• SSRF protection on image URL fetching
• No data routed through third-party proxy services
• All plugin logic runs on your server

External services

This plugin connects to third-party AI services to generate alt text for your images. No data is sent automatically — requests are only made when you explicitly trigger alt text generation (manually, via batch processing, or if you enable auto-generate on upload).

Data sent: When alt text generation is triggered, the plugin sends the image (base64-encoded) along with a text prompt to your chosen AI provider. No personal user data is sent. Your API key is included in the request header for authentication.
