SEOWriting.ai is one of the most popular AI article writers with WordPress auto-publish. MultiPub Pro is structurally similar but built around managing a network of sites rather than producing one article at a time. Here are the practical differences.
| Dimension | MultiPub Pro | SEOWriting.ai |
|---|---|---|
| Cheapest Paid | $17/mo Starter | $14/mo Starter |
| Free Plan | 5 credits, 1 site, no card | 5 articles, 25,000 words, humanizer included |
| Sites Advertised | 3 sites on Starter, scale to unlimited | Sites limit not headline-advertised; multi-CMS focus |
| Cms Targets | WordPress (deep integration) | WordPress, Webflow, Shopify, Wix, Ghost |
| Bulk Link Manager | Included on every paid plan | Internal/external linking yes; bulk swap not advertised |
| Byo Keys | Pro and Pro Max plans | Bundled models (GPT-4o, Claude 3 Opus) on paid tiers |
| Tier | MultiPub Pro | SEOWriting.ai |
|---|---|---|

SEOWriting.ai targets 5 CMS platforms (WordPress, Webflow, Shopify, Wix, Ghost). Breadth is a real value but it also means none of the integrations go particularly deep. MultiPub Pro is WordPress-only — our plugin uses HMAC-signed REST calls, supports per-site categories/tags/authors/featured images, and ships full bulk-update capabilities through the WP REST API.
Our "Network" object groups WordPress sites and shares scheduling rules, voice profiles, blocklists, and link inventory across them. SEOWriting.ai treats each connection as an independent publishing target — fine for single-site, manual for portfolios.
Update an outbound URL once and we propagate it to every post on every site in the network. Designed for affiliate-link rotation. SEOWriting.ai handles internal and external linking at publish time but doesn't advertise post-publish bulk URL rewriting.
On Pro and Pro Max you can use your own DeepSeek, OpenAI, or Anthropic key — provider charges you directly at their published rate, we don't mark up. SEOWriting.ai bundles GPT-4o and Claude 3 Opus into paid plans with no BYO option, which is simpler but caps cost-efficiency at high volume.
No tool wins every category. These are the real advantages of SEOWriting.ai you should weigh before deciding.
SEOWriting.ai Starter is $14/mo with 50 articles and unlimited words. Our Starter is $17/mo with 60 articles and 3 sites. The difference is small but real if you publish on a single site and word-budget matters.
If you publish to more than just WordPress (e.g. a Shopify store blog + a Webflow marketing site), SEOWriting.ai's broader CMS support reduces tooling sprawl. MultiPub Pro is WordPress-only.
Humanizer tool included in the free tier. Auto citations are advertised on their free plan. MultiPub Pro relies on prompt-only anti-AI-detection (works well on non-English; English varies 10-40% on GPTZero per our internal tests) and doesn't embed an "auto citations" feature today.
Their free tier offers 5 articles + 25,000 words + humanizer + syndication, no time limit. Our free tier offers 5 credits + the publishing flow on 1 site. For testing pure generation quality, their free tier gives more headroom.
5 credits, 1 site, no credit card. Decide after you've tried the full publishing flow, not before.
