Which one is for you
Pick Koala if
- Fits if you run a blog or affiliate site and publish articles in volume
- Works for WordPress and Shopify sites that want drafts sent straight to the site
Look elsewhere if
- Not for you if you want a free plan, as the free allowance is one-time
- Watch out: word allowances assume one model, and the others count double or triple
- Tight if you lean on the SEO agent, at 25 messages a month on Starter and 50 on Professional
- Pricey if you write for several brands, as each extra one is $29 a month
- Watch out: refunds come only within 15 days, and only if under 15,000 words and 100 credits were used
Pick Surfer if
- Fits if you write articles meant to rank and want a score to aim for, from $49 a month
- Works for writers who draft in Google Docs or WordPress and want the guidelines there
Look elsewhere if
- Skip it if you want to try it without a card, since the 7-day trial needs one and becomes a paid plan unless cancelled
- Pricey if AI answer tracking is why you're here: Discovery has none, and Standard at $99 tracks 25 prompts weekly in ChatGPT only
- Not for you if you need a full SEO suite, as its research and audits are about content
- Watch out: on yearly plans credits reset once a year, and unlimited documents fall under a fair usage policy
- Pricey if you need the API, which needs Peace of Mind at $299 a month, Enterprise or an add-on

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
