Home / Comparison
We make one of these, so this is a vendor’s comparison, not a review. Every figure came off the vendor’s own page, links back to it, and gets fixed within a week if you tell us it is wrong.
Checked 18 September 2026. Next re-check: first week of October 2026.
It comes down to four things: how you are billed, whose AI account pays for the writing, whether the work happens in the editor, and what happens to the posts you already have. Those are the columns. If we could not check it on a vendor’s own page, it is not here.

Each product name links to the page we read its figures from. Not stated means the vendor did not say either way. A gap in the evidence, not a no.
$9, $19.99 or $49.99 a month for 1, 5 or 15 domains. Annually: $90, $199.90, $499.99. More than 15 domains by quote. We set no word or article cap; your AI provider bills you at its own rate.

getgenie.ai/pricing · 18 September 2026
€5.99, €10.99 or €16.99 a month, annual billing only, ex VAT. Sold separately from Rank Math PRO. Tiers cap features rather than words: 15 long-form articles, then 60, then what they call unlimited. Their FAQ rules out using your own key.
rankmath.com/content-ai · 18 September 2026
Solo $29 a year for one site, Growth $59, Agency $99 with white label. Lifetime licences run $79 to $249. Discounted when we checked, from $49, $99 and $149. Own keys for OpenAI, Claude, OpenRouter and DeepSeek. 1,000+ installs, 3.8 from 10 reviews.
wpwand.com/pricing-plan · 18 September 2026
Free plan, then $9.99 a month for one site. Multi-site licences exist but the page does not price them. Own keys for eight providers including OpenAI, Gemini and Anthropic. 10,000+ installs, 4.6 from 165 reviews.
aipower.org/pricing · 18 September 2026
$10 a month on annual billing for one site and 100 credits, up to $80 for 20 sites. Credits come bundled with 10Web hosting, and the editor only works on sites they host. The standalone plugin closed in September 2024.
10web.io/pricing-platform · 18 September 2026
$25/mo buys 45,000 words, $49 buys 100,000, $99 buys 250,000, and it climbs to $2,000. Annual billing takes 20% off. Better models burn words at two or three times the rate. The old $9 tier is gone: an archived capture from 1 June 2026 shows it at 15,000 words.

If you are the vendor and we have something wrong, tell us and we will correct it within a week.
Licence price is the wrong number to compare, because these products bill for different things. A word plan covers the AI cost and then stops you when the words run out. A per-site licence with your own key is flat, and your provider bills you for what you actually use.
Say you publish 100 articles a month at 1,500 words. That is 150,000 words: Boost at $99 on Koala, Pro at $49 on GetGenie. With us it is a $9 to $49.99 licence depending on how many sites you run, plus provider usage. Our calculator puts that at roughly $3.73 a month on Claude Sonnet 5 with the fact-check pass, using provider prices from 15 September 2026.
Two things we would rather say than bury. That provider bill varies and it is yours to watch, which is why we log what every call cost against the article that caused it. And you need an API account somewhere, a ten-minute job that metered tools save you.
The free official plugin, 50,000+ installs and a 4.6 rating. It puts your own provider keys into the editor through the core Connectors screen. No bulk runs, no fact-check, no white label. If an assistant is all you want, use it. It costs nothing.
$9, $29 or $49 a month for 50,000, 150,000 or 400,000 words. No own key. The WordPress plugin was last updated in 2024; the product is really a web app with CSV imports. contentbot.ai
$24.97 a month or $247 a year, and you bring your own keys. Windows desktop software that publishes to up to 100 sites and runs batches of up to 1,000 posts. The nearest thing to our pricing model outside WordPress. zimmwriter.com
Its plugin is gone from wordpress.org; the listing returns a 404. Existing users work through a Chrome extension. Word-metered, no own key.
SEOWriting.ai belongs here too, but we could not read its pricing page without JavaScript on 15 September 2026, so we are not quoting numbers we did not see.
If you run several sites, publish more than a few pieces a month, want to know what each article cost and whether a second model checked it, and would rather keep old posts current than just pile on new ones, that is who we built this for.
The calculator takes your volume and model choice and returns a figure you can check against your provider’s own billing page.
