Freemium: free forever plan, plus a PRO annual subscription at $39/year
Diogen AI is a WordPress plugin that automates the entire blog content pipeline: it generates article text with OpenAI GPT or Google Gemini, creates matching featured images with DALL-E, Stability AI, or Leonardo AI, and publishes the finished posts as native Gutenberg blocks. Users bring their own AI provider API keys. The free version covers manual post generation, topic discovery, and basic image generation, while the PRO plan ($39/year) adds a cron-based autopilot scheduler for fully hands-off publishing, bulk topic planning with duplicate prevention, five writing styles (Professional, Conversational, Creative, Academic, Technical), custom article outlines, premium image models, category-based author assignment, and detailed generation logs. It is built for bloggers, niche and affiliate site owners, SEO agencies, and indie founders who want to scale WordPress content output without manually writing every post.
