hrefStack vs SEOWriting.ai (2026): which should you pick?

Pick hrefStack if

• Fits if you're a small team that wants keyword gaps turned into published articles
• Works for sites on WordPress, Shopify, Webflow, Ghost or Sanity

Look elsewhere if

• Tight if you stay free, at 10,000 words a month, 2,000 per article and no research features
• Pricey if you need the API, custom prompts or team seats, which wait on Pro at $69 a month
• Watch out: allowances are counted in words, so long articles mean fewer of them
• Watch out: the AI agent and competitor gaps are listed only from Starter at $45 a month

Pick SEOWriting.ai if

• Fits if you run an affiliate site and publish product roundups and reviews
• Works for bloggers who want articles written and scheduled on WordPress in bulk

Look elsewhere if

• Watch out: the dearer AI models use 4 or 10 credits an article, not 1
• Tight if you're staying free, at 3 articles with no bulk writing, brand voice or links
• Skip it if your site isn't on WordPress or Shopify, as no other platform is named
• Watch out: a full refund is only possible within 14 days and before 50,000 words and 5 generations

hrefStack

• The free plan has no research features and caps articles at 2,000 words and 10,000 words a month.
• API access, custom prompts and team collaboration need the Pro plan.
• Allowances are counted in words, not articles, so the number of articles a month depends on their length.
• The AI agent and the research tools, competitor gaps included, are listed only from the Starter plan up.

SEOWriting.ai

• Credits per article depend on the AI model: most use 1, advanced OpenAI and Anthropic models use 4, and the most powerful Anthropic model uses 10.
• The free plan stops at 3 articles and 25,000 words, with no bulk generation, brand voice or automatic linking.
• A full refund is possible only within 14 days of the first purchase and before 50,000 words and 5 generations are used.
• Direct publishing connects to WordPress and Shopify; its pricing and help pages name no other site platforms.
