📚 Documentation Before you start, check out the complete documentation — provider setup guides, content and image generation workflows, Magic Wand usage, SEO modules, developer hooks and REST API reference, and troubleshooting.

Quick Intro No Ads Plugin. Completely Free. No extra fees — connect directly through your own API keys. 1 Minute Installation. Configure one or more providers and start generating posts, images, metadata, and SEO improvements from your WordPress admin.

I built this free AI engine to bring modern AI workflows directly into WordPress. Create SEO-optimized titles, generate full blog posts, write excerpts, create images, generate image ALT text, and refine existing text without leaving your editor.

Start simple: open any post, click “SmartyPress AI Writer” in the toolbar, and generate a title. Then try Magic Wand on any block — select text, pick an action, and watch AI transform your content. Need 50 blog posts at once, media metadata, or SEO fixes? The plugin includes dedicated modules for those workflows too.

This AI engine gives you a modular workspace: Content Generator, Magic Wand inline editing, Image Generator, Image ALT Generation, SEO Analysis, and SEO Optimization. Use the provider that fits each task: OpenAI, Deepseek, Anthropic Claude, OpenRouter, Yandex, or GigaChat.

Disclaimer SmartyPress AI Engine connects your site to third-party AI services. You need your own API keys and must follow the terms set by the providers you enable, such as OpenAI, Deepseek, Anthropic, OpenRouter, Yandex Cloud, or GigaChat. The developer is not responsible for AI-generated content. See the External Services section below for full details.

External Services IMPORTANT: This plugin sends your prompts and related content to third-party AI services when you use a generation feature. Only providers you configure with your own API key are contacted, and only when you click Generate/Regenerate, use Magic Wand, or (if enabled by the admin) on media upload for ALT text — never in the background.

Data sent typically includes your prompt, the related post/image content, and generation settings (model, temperature, tokens); for image editing or vision-based metadata it also includes the image file. No WordPress user data, passwords, or site configuration are ever sent. API keys and generated content are stored only in your WordPress database; you can remove a key from Settings at any time to stop all requests to that provider.
