SEO Writing AI vs Grammarly: Generation vs Polish

Grammarly and SEO Writing AI both serve content creators, but they approach the job very differently. After testing both, here’s where each tool actually delivers — and where it falls short.

Quick Verdict

SEO Writing AI is purpose-built for SEO blog content. It runs SERP analysis on your keyword, generates articles with proper heading hierarchies, includes AI images, and publishes directly to WordPress. Starting at $14/mo for 50 articles, the per-article cost is hard to beat.

Grammarly is the industry-standard writing assistant for grammar, spelling, clarity, and tone detection. At $12/mo for Premium, it polishes existing text — but it doesn’t generate content. These are fundamentally different tools that complement each other well.

If your primary goal is producing SEO-optimized blog articles at scale, SEO Writing AI is the more focused and affordable option. If you need grammar checking, spelling correction, clarity improvements, and tone detection for content you’ve already written, Grammarly may be the better fit.

Key Differences

Where SEO Writing AI Wins

SEO Writing AI generates complete articles from scratch — 1500-3000 word SEO-optimized pieces with proper heading hierarchies, meta tags, and AI images. Grammarly can’t create content at all.

The SERP analysis feature is the standout here. SEO Writing AI doesn’t just generate content — it analyzes what’s currently ranking for your keyword and structures the article to compete. The WordPress auto-publish with images is another genuine time-saver for bloggers managing multiple sites.

Pricing Comparison

SEO Writing AI offers a free tier with 5 articles per month — enough to test the tool thoroughly. The Pro plan at $14/mo gives you 50 articles, working out to about $0.28 per article. The $24/mo plan bumps that to 100 articles.

Grammarly starts at $12/mo, which may make sense depending on your specific workflow needs.
