SEO.AI vs Seonix

SEO.AI

Built and priced for a business that wants SEO to simply happen without hiring anyone. If you already have an SEO specialist, you are paying $149/month for work they would rather do themselves with tools they control.

Pros

• +Closes the whole loop — topic, draft, publish, monitor — rather than stopping at a draft
• +Direct connectors for WordPress, Webflow, Wix and Shopify
• +Monthly plans have no lock-in and a 7-day trial precedes payment

Cons

• −$149/month buys exactly one site in one language
• −The automated link exchange is a network by another name and carries real ranking risk
• −No public API and no free tier, only the trial

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
