Rankai

Need a batch of search-focused blog pages published every month without hiring an agency? Rankai produces them for you.

Rankai is an AI SEO writing tool that works as an autonomous agency, creating content meant to bring organic traffic from Google and from AI search engines such as ChatGPT, Gemini and Perplexity.

Its main hook is a 'Rewrite Until It Works' policy: pages that do not perform get rewritten automatically rather than left alone.

Output volume is high, and the appeal is a significant cost cut compared with a traditional agency.

Early results often show up in under 30 days, though the full compounding effect of SEO takes roughly 3 to 6 months of steady investment, so expect a patient timeline.

The catch is in the plans.

The Starter plan is limited to 8 pages per month, and human expert vetting of the content is reserved for higher tiers.

If you want a person reviewing every page, plan on paying more.

Rankai is listed as backed by Y Combinator, Microsoft, a16z and OpenAI.
