Description
Supercharge your site’s SEO and accessibility with the ultimate AI alt text generator.
🌟 Pro | 📖 Documentation | ℹ️ Support
AI Alt Text uses OpenAI to automatically generate descriptive, context-aware alt text for your images. No more skipping alt attributes or guessing what to write. This plugin gives you fast, smart alt text that makes your site more inclusive and search-friendly.
“We recently tested the AI Image Alt Text plugin for WordPress – and we’re impressed. What really stood out: the plugin doesn’t just insert generic labels. Instead, it reads the surrounding content and creates alt descriptions that are semantically relevant – even in multiple languages, including German. This makes it especially valuable for websites with multilingual content or SEO-conscious editors who care about accessibility and nuanced on-page optimization.”
