WP Content Helper

A powerful Grammarly-like AI writing assistant for WordPress, powered by Google Gemini API.

AI-powered writing assistance directly into your WordPress editor. Unlike other AI plugins, each user manages their own Google Gemini API key, ensuring privacy and individual control. The plugin seamlessly integrates with Gutenberg's toolbar, providing instant AI suggestions right where you write.

• ✏️ AI Text Improvement - Enhance clarity and grammar
• ✓ Grammar Checking - Find and fix errors with explanations
• 🎨 Content Rewriting - 6 different tones (professional, casual, friendly, etc.)
