Six products that will write and publish SEO articles for a small business every month. At the entry price we are the cheapest per article, and one of only two that also post to social networks. Several of them do things we do not do at all, and those are under the table rather than left out of it.
Only what each vendor states publicly is listed here, read from their own pricing pages in September 2026. Where a vendor does not state something, this table says so rather than guessing. Prices carrying a marker link to the page they were read from.

What the columns cannot hold
A review step is not the same as a gate
Approval is ordinary in this category now. Koala and RightBlogger let you keep drafts for review or publish automatically, Soro lets you approve or auto-publish, SEObot will email you a list to accept or decline, Frase gives you a dial. The difference worth paying for is not that a review exists, it is that ours cannot be turned off, and that a publish is refused unless the bytes still match the version you approved. Everybody else's is a setting, and most of them default it towards shipping.
Fact checking is advertised more often than it is guaranteed
SEObot advertises citation of sources and Koala offers citations when you want them; Outrank will put human editors on it for $1,399 a month. What no page here states is the whole of what ours does: the factual claims we write traced to sources fetched at the time of writing, checked by software and then by a second model that did not write them, and a piece held back rather than published when a claim has nothing behind it. It is free, it is on, and there is no setting that turns it off.
If you want a person as well, human review is an add-on at $580 a month for each set of 30 articles. A reviewer reads each article, with the social posts written from it, against a written checklist before it reaches your queue, and sends back the pieces that fail. It sits on top of the standard checking rather than replacing it, and you still approve every piece.
The bill is the comparison
Every other product here is an article tool. If you also want the posts that carry the article, and the positions those articles reach, and whether the assistants name you, those are separate subscriptions with separate dashboards. One plan here covers all of it, which is the argument the whole comparison rests on and the reason we can be cheapest per article at the entry price without being cheapest at everything.
Honestly
When to buy one of these instead
A comparison with only columns its author wins is not a comparison. These are the cases where one of the six above is the better purchase, and we would rather you found them here than a month after paying us.
Your site is Shopify, Webflow, Ghost, Notion or Wix. We publish to WordPress, or to a blog we host on a subdomain, movable to one of your own. Any other site can collect approved articles itself with a delivery key, but your developer writes that end, and we ship no plugin or app for those platforms. Soro, SEObot, Outrank, Koala and Frase each publish directly to between four and nine platforms, and Soro ships WordPress and Shopify plugins on top.
You want a published page watched continuously and fixed the week it slips. Frase watches a published page and rewrites it when it starts losing ground, and RightBlogger audits live pages every three days, daily on its Agency plan. We refresh too, and on a slower clock: when a page you published starts slipping in rank, the next week's plan proposes the rewrite with the evidence, and you approve it like everything else. By default at most a fifth of each plan goes on upkeep. If you need the fix within days rather than with the next plan, buy the tool that watches daily.
You want AI answers watched at scale rather than sampled. Frase tracks 50 to 500 prompts daily and RightBlogger ships an AI brand monitor. We ask four assistants about 2 to 6 searches, weekly, or daily on Max. That is a reporting layer on a writing service, not an AI visibility product, and it should not be bought as one.
You want a person to check the facts. Outrank sells professional human editors who review and fact-check every article, as a $1,399 a month add-on. Ours is free and mandatory, and the standard checking is not a human being: it is software and a second model. We also sell human review, $580 a month for each set of 30 articles: a reviewer reads each article against a written checklist and sends back the ones that fail. That is not a second fact-check of every claim, so if a person re-checking every claim is what you want, Outrank's editors are the closer match.
You run more than one website, or you run them for clients. One PlainQuill plan is one business. RightBlogger connects 3 or 10 sites, Frase 5 or 10, and both sell team seats and client reporting. A per-client offering of ours, volume priced and with white-label monthly reports, is in build. Until it is on sale, one plan is one business and there is nothing here to buy for a second one.
You plan by behaviour on your own site, in Google Analytics. Koala grounds its agent in your Search Console and Analytics. We read Search Console as well now: you add our reader to your property as a restricted user, and every query Google reports for your whole site goes to the planner rather than only the pages we wrote. A Bing Webmaster property does the same if you connect one, and you can connect both. Alongside those sit reader numbers for a blog we host, your tracked positions, the domains ahead of you on those searches and whether the assistants cite you. You argue with it in a chat: each week's plan before you approve it, any one-off article, and your standing instructions at any time. What we do not read is Google Analytics, or any other analytics product, so if you plan by what visitors do once they are on your site rather than by what you rank for, Koala is the one that can see that.
You publish in several languages. Soro advertises 50 or more, SEObot 50, Frase 70 or more and Outrank 150 or more. We do not advertise multilingual publishing, so if that is the requirement, buy from somebody who sells it.
You want longer than a week to change your mind. Koala and RightBlogger each let you start on a free account before paying anything. After a payment, Soro refunds within 14 days, Koala within 15 while little of the plan has been used, and RightBlogger within 30. Ours is 7 days from a payment, and the whole payment comes back while fewer than 7 articles have been generated since it. Shorter, and stated rather than buried.
None of these tools, ours included, can promise you a search ranking. Anyone who does is selling something they do not control.

See the output before you commit
Read the blog we publish for ourselves, through the same pipeline, then run it on your own site. Ask within 7 days of a payment and you get all of it back while fewer than 7 articles have been generated since that payment. From 7 on, you get back the part that covers the articles not yet generated.
