SEO Writing AI vs Seonix

SEO Writing AI

SEO Writing is one of the cheaper ways to get bulk article generation with real SERP analysis and hands-off publishing attached. The affiliate-format models and the WordPress and Shopify hooks are what separate it from a generic writing assistant. The credit maths is the constraint: 50 credits on the entry plan is a modest month once you factor in reruns.

Pros

• +Analyses live SERP competitors before generating rather than writing blind
• +Bulk generation of up to 100 articles per batch with WordPress auto-posting
• +Built-in content scoring checker and 20-plus affiliate-format models
• +Shopify app and MCP generation on top of the WordPress plugin, across 48 languages

Cons

• −50 credits on the Starter plan goes quickly once you regenerate drafts
• −The advertised $14 price needs a year paid up front; monthly is $19
• −No company name, country or address is published anywhere on the site

Seonix

Seonix is an SEO autopilot rather than a writing editor: it researches the keywords, drafts each article from the pages already ranking, scores it on the page, publishes it as a native post to WordPress, Ghost, Webflow, Shopify or Wix on a schedule, and tracks the results in Search Console and in ChatGPT answers. The entry plan is $49 a month for 30 published articles, with a free audit plan in front of it. It launched in 2026, so the track record is short and the company behind it is small — the trade for a price that undercuts the autopilots and editors it competes with.

Pros

• +Runs the whole loop — keyword research, drafting, on-page scoring, scheduled publishing and rank tracking — instead of one editor you paste into
• +30 published articles a month on the $49 plan — three times Frase's Starter allowance at a similar price
• +Free plan with a full technical audit, Site Health and an AI-search readiness check before any money changes hands
• +Articles arrive as native CMS posts with images, meta tags, internal links and schema already in place, on WordPress, Ghost, Webflow, Shopify and Wix, and an API for anything else
• +Reports where the brand shows up in ChatGPT and Gemini answers, not only in Google rankings

Cons

• −Launched in 2026 — a short track record, and one small company behind it
• −One paid tier between Free and Enterprise: more than 30 articles a month, or a second site, means a custom quote
• −The 14-day refund applies only while nothing has been generated on the account
