Rank Math has emerged as the most feature-rich free WordPress SEO plugin, and its Content AI assistant puts it ahead of Yoast in the AI writing department. It can generate meta descriptions, titles, and even content outlines directly in the WordPress editor. But there are limitations.
The Credit System
Rank Math gives you 5 free AI credits. Each meta description generation uses at least one credit. A site with 100 pages would need 100 credits just for meta descriptions — that costs money. Txtory has no credits, no counters, and no upsell. Generate as many as you need.
Integrated vs Standalone
Rank Math's advantage is integration. The AI writes the description and immediately places it in the correct meta field, checks it against SEO best practices, and previews how it will look in search results. With Txtory, you generate, copy, and paste. The extra steps take seconds but the workflow is less seamless.
The Bottom Line
If you use WordPress and Rank Math, use Txtory to generate descriptions and Rank Math to analyze and place them — this saves your AI credits for other tasks. If you do not use WordPress, Txtory is the straightforward choice.
