SmartyPress AI Engine — Free AI Engine for Content Generation

SmartyPress AI Engine is a free multi-provider AI engine for WordPress. Generate posts, images, SEO metadata, image ALT text, and content improvements with OpenAI, Deepseek, Anthropic Claude, OpenRouter, YandexGPT, YandexART, and GigaChat.

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.
