seo.ai: pick it when it fits better
seo.ai calls itself an AI-powered SEO agent. Its homepage lists automatic content creation and publishing, backlinks through a link exchange network, Domain Rating tracking, and support for "50+ languages." It lists an optional approval step before publishing and a 7-day trial (seo.ai).
The pricing page lists two plans. Single Site is $149 a month for 1 website in 1 language. Multi Site is $299 a month for up to 3 websites or languages. Both list Google Ads creation and optimization, performance monitoring, backlinks and free human support. Annual billing is listed with a 25% discount, but no yearly figure is shown. You can choose automatic publishing, drafts, or review in the platform (seo.ai/pricing).
Pick it if you want one agent that handles articles, backlinks and Google Ads, with human support, and you publish to Shopify, Wix, Squarespace or Magento.

What a fact check compares
"Fact-checked" can mean different things, so ask each tool what it compares.
Paperboy's check works like this (paperboyseo.com):
- Every number in the article must appear in the source it links to.
- Every cited sentence is compared with that source's own words.
- If anything fails, the article gets one rewrite.
- If it still fails, it is held for you instead of being published.
That is a check against the source text. It does not tell you whether the source itself is right. seo.ai describes human spot checks by SEO specialists, which is a different kind of review (seo.ai). Whatever you choose, check names and numbers yourself. No tool can promise rankings, traffic or AI citations.
How to choose
- Want articles, backlinks and Google Ads handled by one agent: seo.ai.
- Want an SEO agent and writer with a free start: Koala.
- Want a daily article in a flat plan: RankYak.
- Want 30 articles a month with backlinks: Outrank.
- Want a check that states what it compares, from $49 a month: Paperboy.
