Which one is for you

Pick AI SEO Copilot if

  • Fits if you design in Webflow and want a page checklist while you build
  • Works for freelancers who want a free SEO check for client sites

Look elsewhere if

  • Skip it if your site isn't on Webflow, as it only runs inside the Webflow Designer
  • Too light for site-wide audits, since each check covers one page and one keyword
  • Watch out: a page must be published to staging or production before it can be checked
  • Not for you if you want a support contract, as help is by email, GitHub and a feature board

Pick Semflow if

  • Fits if you build client sites in Webflow or Framer and handle their SEO
  • Works for agencies that want one subscription for unlimited sites

Look elsewhere if

  • Not for you if you want a free plan, as there's only a 7-day trial
  • Pricey if you need keyword research, rank tracking or schema, which need Pro at $29 a month or $19 yearly
  • Watch out: rank tracking is shown week over week, not daily

How we grade them

3.0GPAAI SEO CopilotVery good2.4GPASemflowFair
Value for money
ANothing to pay, and no account, email or card asked for: the 18 checks, the score and the AI suggestions are all free. Three tools in this category are free outright, and the makers ask for GitHub donations instead.
CStarter is $10 a month billed yearly ($14 monthly) for unlimited sites, a little above this category's $8.25 cheaper quarter. Pro, with keyword research, rank tracking and schema, is $19 a month yearly or $29 monthly.
Free plan and trial
AFree outright with no paid tier, so there's no cap to reach. The code is open source under the MIT license.
CNo free plan, but both plans have a 7-day free trial, and the listing doesn't say it needs a card.
Features
C18 checks on titles, descriptions, headings, links, images and schema, a score by category, AI fixes you apply in the Designer, alt text and H2 rewrites, and schema advice. It checks one page and one keyword at a time and doesn't crawl the site.
BSite audits with fixes, AI titles and descriptions, page keywords, page speed, site monitoring and AI visibility, then keyword research, rank tracking, a schema builder, robots.txt help and PDF reports on Pro. It covers the job, though rank tracking is weekly.
Ease of use
BNo store rating on record, but there's no account to make: open it in the Designer, type a keyword and run the check. The page does have to be published to staging or production first.
CNo store rating on record. It opens inside Webflow or Framer, but you add each site, set a primary and up to three secondary keywords per page and work through the audit.
Platforms and integrations
CWebflow only, inside the Designer, with OpenAI behind the suggestions. No phone or desktop app, and nothing for other site builders.
BWeb, inside Webflow and as a Framer plugin, plus a Chrome extension for sites built anywhere, with Google PageSpeed Insights. One subscription covers all three. No phone or desktop app.

Semflow

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.
