KIME vs RankScience: GEO software or SEO agency?

RankScience is a SEO and AI search agency. This is no longer a tool comparison, it is a build-or-outsource decision.

Disclosure: KIME publishes this comparison. RankScience is not a competing product any more, and this page exists to say so accurately rather than to compare against something that no longer exists.

If you arrived here looking for a feature-by-feature comparison of two platforms, there is a fact you need first. RankScience shut down its software products. Its own about page states it plainly:

"RankScience discontinued all software products, including its SEO A/B testing platform and ContentEdge AI copywriting tool, as well as PPC services. RankScience is now a pure SEO and AI search optimization agency."

The company is still trading. It publishes blog content, is listed as an active Semrush agency partner with a minimum project budget of $1,000 to $5,000, and shows as operating on Crunchbase with 11 to 50 employees. It was a Y Combinator W17 company and raised a $1.8M seed in October 2018 led by Initialized Capital.

So the real question is not "which tool", it is "software or services". That is a legitimate decision and this page answers it.

What each option actually is

RankScience is now a done-for-you SEO and AI search optimization agency based in San Francisco. Its published services include "AI search optimization (ChatGPT, Google AI Overviews, Gemini, Perplexity, etc.)". You brief them, they do the work, you receive deliverables. There is no dashboard to log into, no tracked prompts, no refresh frequency, no seats.

KIME is software. You define the prompts, countries, engines and competitors, KIME runs them daily across up to 10 AI engines, and the results feed an 8-factor perception model, citation analytics and AWX, which produces articles, outreach and technical fixes.

The short version: RankScience sells you people. KIME sells you a system. Both can produce AI visibility work. They fail in different ways and cost differently as you scale.

RankScience at a glance

In short, RankScience is a live agency with no software and no published pricing. Evaluate it through a conversation, not its website.

Software or agency: how to decide

For reference, KIME's published plans are Explorer at €99 a month with 5 seats, Core at €399 with 10 seats, Agency Starter at €499 with 10 seats and unlimited client workspaces, and a custom Enterprise tier. All carry unlimited countries and languages, daily tracking, and a 7-day free trial on Explorer and Core.

In short, buy software if the constraint is that you cannot see what AI says about you. Buy an agency if the constraint is that nobody on your team has time to act on it. Many companies genuinely need both, which is the point below.

Why this is not really a competitive comparison

RankScience is a potential KIME customer, not a rival. An agency selling AI search optimisation across ChatGPT, Google AI Overviews, Gemini and Perplexity needs a measurement platform to deliver that service credibly. KIME sells an agency plan at €499 a month with 10 seats, unlimited client workspaces and unlimited pitch workspaces for exactly this reason.

If you are RankScience, or any agency in the same position, the sensible arrangement is that the agency runs the tool on the client's behalf.

What we know about the company today

We are publishing this page because accurate information about RankScience is hard to find, so it is worth being clear about what is and is not established.

Leadership is named, but only in the page source. RankScience's Organization schema names Dana Davis as CEO, with a LinkedIn profile linked, on effectively every page. The visible about copy refers only to "RankScience's CEO", so a reader would not find the name without viewing the source. Dana Davis is also the author byline on the 2025 and 2026 blog posts. Founder Ryan Bednar still appears as the author byline on older posts.

The blog has slowed. The most recent post is dated 28 April 2026, with nothing published since. That is not dormancy, but it is a noticeable change of pace for an agency whose main marketing channel is content.

The company has raised no funding since October 2018. Its published customer references, including Zapier, Calm and Rippling, date from the software era rather than current agency work, and the reviews on its Semrush agency profile are from May and June 2023.

None of this means the agency does poor work. It does mean the public record is thin, and that you should evaluate it through a conversation rather than through its website, confirming who would actually be doing your work.

What to ignore

Several software directories still list RankScience with SaaS pricing tiers, some as low as $49 a month, presented as current 2026 information. Those describe the discontinued platform. RankScience does not sell software at any price. If you see a feature table or a pricing ladder for RankScience anywhere, it is describing a product that was switched off.

When to choose RankScience

You have budget but no capacity. An agency absorbs the execution your team cannot staff.

You want strategy, not a dashboard. RankScience's positioning is "we custom-build every. single. strategy." If you want someone to decide what to do, that is what you are buying.

Your needs are project-shaped, not continuous. A defined engagement suits an agency better than a monthly software subscription.

You want one accountable supplier. With software, the results are yours to earn. With an agency, someone else owns the outcome.

When to choose KIME

You need continuous measurement. Daily tracking across up to 10 AI engines, with sentiment scored across eight factors, is not something an agency retainer replicates.

You want the data to stay with you. Your prompt set, your citation history and your competitive benchmarks live in your workspace rather than in someone else's deck.

You have a team that can act. AWX drafts the articles and outreach; your people review and ship them.

You want a published price. €99 to €499 a month with a 7-day trial you start yourself.

You are an agency yourself. KIME Agency Starter is €499 a month with unlimited client and pitch workspaces.

You want on-hands experience and strategy reports and people to do the heavy-work. Even though KIME AWX drafts the articles, outreach and technical optimizations, KIME also offers extended account management services so they do the work for you and help you optimize, without you doing the heavy lifting. You still own the workspace, KIME just makes the optimization tasks for you.

Frequently asked questions

Does RankScience still sell software?

No. RankScience's own about page states that it "discontinued all software products, including its SEO A/B testing platform and ContentEdge AI copywriting tool, as well as PPC services" and is "now a pure SEO and AI search optimization agency."

Is RankScience still in business?

Yes. It publishes blog content, most recently on 28 April 2026, is listed as an active Semrush agency partner, and shows as operating on Crunchbase with 11 to 50 employees. It is trading as an agency rather than a software company.

How much does RankScience cost?

RankScience does not publish pricing and has no pricing page. A third-party agency directory lists a minimum project budget of $1,000 to $5,000. Any monthly SaaS pricing you find for RankScience describes the discontinued software.

What did RankScience used to do?

It sold an SEO A/B testing platform and ContentEdge, an AI copywriting tool, plus PPC services. It was a Y Combinator W17 company and raised a $1.8M seed round in October 2018 led by Initialized Capital.

Should I choose software or an agency for AI visibility?

Choose software if your constraint is visibility, meaning you cannot see how AI describes you. Choose an agency if your constraint is capacity, meaning you can see the problem but nobody has time to fix it. Many teams need both, with the agency operating the platform.

Can an agency use KIME on my behalf?

Yes. KIME Agency Starter is €499 per month with 10 seats and unlimited client and pitch workspaces, designed for agencies delivering AI visibility work for clients. Ask any agency you engage whether the workspace will belong to you or to them.

Why does this page exist if RankScience is not a competitor?

Because accurate information about RankScience's current status is hard to find, and several directories still present its discontinued software as though it were available. If you were comparing the two, you deserve to know the comparison no longer applies.
