What Sorabun Does
A one-page overview of what parts of article writing you can automate
Sorabun automates the article-writing process
Sorabun is a plugin that runs the entire article-writing process from inside the WordPress admin screen. What sets it apart from AI tools that just write text is that it treats everything from choosing keywords to improving articles after publication as a single flow.
Four stages
- Plan: The AI Editor-in-Chief analyzes your site and proposes, on a calendar, which articles to publish and in what order
- Generate: Creates the article body, featured image, diagrams, and internal links all together
- Monitor: Measures the search ranking and actual Search Console data for published articles every day
- Improve: AI rewrites articles that aren't performing well
Because these four stages are connected, you're less likely to end up in situations like "I wrote the article but never checked its ranking" or "I'm watching the ranking but don't have time to fix it."
Runs on your own API key
Sorabun runs on the API key of the AI you set up (Gemini / ChatGPT / Claude / Grok / DeepSeek). Because the plugin itself doesn't bundle in any AI usage fees, the cost per article stays low. The Gemini API has a free tier, so you can try it out at no cost first.
Article text costs roughly 10-20 yen, and each featured image or diagram costs roughly 5-10 yen. A standard article (one featured image plus two diagrams) costs about 30-60 yen.
Lite and Pro editions
Even the free Sorabun Lite lets you generate articles, featured images, and diagrams. The editorial calendar, rank tracking, scheduled publishing, and podcast distribution are Pro features. For details, see Differences between Lite and Pro.
