PurePen AI

PurePen AI is a free AI content generator plugin for WordPress that lets you create publication-ready blog posts, page content, and SEO metadata without leaving the editor. Choose from 8 leading AI providers, enter a topic, and get a complete article — titles, full HTML body, tags, and meta excerpt — in seconds.

Whether you are a blogger, content marketer, or agency managing dozens of sites, PurePen AI saves hours of writing time while keeping you in full control of the output.

Why PurePen AI?

• Start for free — no API key needed. Five free generations are included on activation so you can try every feature immediately.
• Guided API key setup. When you are ready for unlimited use, a built-in step-by-step wizard walks you through getting a free API key from Groq or OpenRouter in under 2 minutes — no credit card required.
• Save your favourite settings as templates. Store named presets (provider + tone + language + length) and load them in one click. Never re-configure the same settings twice.
• Works inside the editor. The PurePen AI panel appears automatically in the Gutenberg sidebar and the Classic Editor meta box — no separate dashboard needed to generate content.
• Your data stays private. Content is sent directly from your server to the AI provider you choose. Nothing passes through our servers.
