AI Website Optimisation Tools Compared for B2B in 2026

The short answer

If you want to run your own A/B tests at a published price, look at Varify. If your site is on Webflow, look at Webflow Optimize (formerly Intellimize). If you want experts to run optimisation for you, look at Coframe. If you would move your website to a new platform that ships weekly improvements, look at Optise. If you run large volumes of paid traffic and want personalised landing experiences, look at Fibr. Mutiny has changed direction and is now a sales assistant. Artiweave, which we make, is in private beta and is not available to buy yet.

How we compared them

We visited each vendor's website on 3 November 2026 and recorded only what the vendor publishes about itself: what the product does, who it says it is for, how changes reach the live site, and the prices on its own pricing page. Where a vendor does not publish a price, we say so. We have not used these products on a client site, we have not tested their results, and we do not repeat their performance claims. Vendors change their products and pricing often, so check each source before you decide. Each vendor's section links to the page we used.

Two questions separate these tools more than any feature list:

Who decides what goes live? Some tools ask a person to approve each change. Others let an algorithm decide which version each visitor sees, once you have supplied the versions. Neither is wrong, but they suit different teams. We explain the case for approval in human-in-the-loop website changes.
Where does the website live? Most of these tools work on your existing site through a script. Optise asks you to move your website onto its platform. Webflow Optimize works natively on Webflow and through a script elsewhere.

Optise

What it does. Optise, which lists offices in Reykjavík and Palo Alto, calls itself "the self-improving B2B website platform". Its site describes four products: analytics, automated improvements, a CMS and a content creator. Its Intelligence Engine reviews the site, gives it a score and recommends "the next best improvements", which can include copy and calls to action, technical fixes, internal links, new subpages and blog posts, and visibility in Google and AI answers¹³.

Where the site lives. Optise is a website platform as well as an optimisation tool. Its switching page says it rebuilds your website on Optise from your existing content and brand, you review and approve every page, and your current site stays online until you go live². It compares itself with Webflow, Framer, WordPress and HubSpot CMS rather than with testing tools.

How changes go live. Its FAQ says: "Optise recommends improvements and can ship them for you, but you decide what gets published." Its automated improvements page says it "ships them for you when you approve"¹³.

Who it suits. By its own description, B2B marketers who want a prioritised list of improvements shipped for them, and whose developers or agency are a bottleneck. It suits a team that is happy to move its website onto a new platform.

Pricing. Not published. The site says "Free to start. No credit card."³

Webflow Optimize (formerly Intellimize)

Status. Webflow announced its acquisition of Intellimize, "an AI-driven website personalization and conversion rate optimization platform", in April 2024⁴⁵. Intellimize.com now redirects to Webflow Optimize, so we treat that as the current product.

What it does. Webflow describes three parts: experiments (A/B tests), personalisation for audience segments, and "Optimize with AI", which can "test multiple variables at once, automate testing, and personalize the on-page experience for each unique visitor"⁶.

How changes go live. You create the variants. Webflow says you can then "let AI Optimize make real-time decisions about which audiences see what content in order to maximize conversions", and its FAQ describes the AI "automatically allocating traffic" to the best-performing variations⁶. So people decide what can be shown, and the algorithm decides who sees it.

Who it suits. Marketing teams on Webflow, and larger sites elsewhere. Webflow's FAQ says Optimize "works with any CMS": natively on Webflow sites, and through a JavaScript snippet on other sites⁶. AI-driven allocation learns from visitor behaviour, so it suits sites with enough traffic for the algorithm to learn from.

Pricing. Webflow's pricing page lists Optimize as an add-on to a site plan from $299 a month, "based on # of page views", with up to five concurrent optimisations. For sites not built on Webflow, it says to contact sales⁷.

Fibr

What it does. Fibr calls itself an "Experience Optimization Platform for Humans and AI-Agents". For human visitors, its AI agents "analyze visitor intent, identify opportunities, develop hypotheses, and create and test experiences at scale", with a focus on matching pages to ads and traffic sources. A newer product, which Fibr calls Agent Experience Optimization, creates versions of your pages for AI platforms, "served on the same URL and invisible to human visitors"⁸. Fibr presents this feature as aimed at AI platforms. Google's spam policies define cloaking as showing search engines and people different content with the intent to manipulate rankings and mislead users¹⁴, so if you consider the feature, ask Fibr how it treats search engine crawlers.

How changes go live. Fibr's site says: "Review every variation and approve what goes live. You stay in control before anything goes live."⁸

Who it suits. Fibr's pricing page describes its Enterprise plan as "for enterprises looking to personalize at scale" and its Starter plan as "for growing businesses"⁹. Its homepage lists industries including financial services, healthcare, insurance and B2B SaaS, and use cases built around traffic sources such as paid social and paid search⁸, so it suits teams that spend heavily on ads and want landing experiences matched to them.

Pricing. Not published. The pricing page lists Starter, Enterprise and Agency plans, each with a "Book a Demo" button⁹.

Varify

What it does. Varify describes itself as an A/B testing platform developed in Germany, with A/B, split URL and multi-page tests, a visual and code editor, and results evaluated in Google Analytics 4. Its AI features include a CRO audit with prioritised test ideas, and "Prompt Based Experimentation", in which you describe a test in plain language and the AI "creates the variation, writes the code and builds the experiment"¹⁰¹¹.

How changes go live. As with most testing tools, you build or approve a variation and start the test yourself. Varify says you can then "keep a winning variation live with one click, without waiting for a developer release"¹¹.

Who it suits. Marketing and CRO teams and agencies who want to run their own tests, at a published price that does not rise with traffic. Like any A/B testing tool, it needs enough traffic to reach a conclusion; see CRO for low-traffic B2B websites for what to do when you do not have it.

Pricing. Published, in euros: Growth €199 a month billed annually (€249 billed monthly), Pro €249 a month billed annually (€349 billed monthly) and Enterprise from €799 a month, billed annually. All plans include unlimited traffic when results are measured through GA4. AI features start on the Pro plan, where they are billed in AI credits (a monthly credit package) or through your own AI provider key; the Enterprise plan includes a credit volume¹¹.

Coframe

What it does. Coframe describes "expert-managed conversion rate optimization, end-to-end". It generates copy, code and images for variations of your pages, then tests and personalises them¹².

How changes go live. Coframe's three steps are: "We analyze your site", "You approve the variants" ("You review and approve what goes live"), then "Coframe deploys, personalizes, and tracks lift". It also mentions "automatic fallbacks"¹².

Who it suits. Teams who want optimisation run for them rather than a tool to operate. Its testimonials come from growth and experimentation leaders, and it positions itself against both SaaS tools and CRO agencies¹².

Pricing. Not published. The site offers a demo.

Mutiny: no longer a website optimisation tool

Status. Mutiny was widely known for B2B website personalisation. Its site now describes it as "the sales assistant built for customer-facing work": it takes meeting notes, drafts follow-up emails, proposals and decks "for your review", and offers templates for assets such as "1:1 ABM", "Vertical Landing Page" and "Deal Room"¹³. As of 3 November 2026, neither its homepage nor its pricing page describes on-site personalisation or testing. Croct, which sells a competing personalisation product, says Mutiny discontinued its website personalisation product on 8 April 2026¹⁶. We could not confirm that from Mutiny's own pages, so treat it as unconfirmed.

Who it suits. Sales and marketing teams who want help producing customer-facing content. If you need a tool that changes your website, Mutiny's current site does not describe one.

Pricing. Published for the sales assistant: Free ($0), Business ($50 a month) and Enterprise ("Starting at $40,000/year")¹³.

Artiweave (private beta)

What it does. Artiweave is our product, so read this section with that in mind. It works on the B2B website you already have. It finds opportunities from evidence (a crawl, Search Console and performance data), proposes specific changes with the reasoning, and measures each published change, reporting "inconclusive" and "insufficient traffic" when that is the honest answer. Showing which companies visit your site is planned but not live yet.

How changes go live. A marketer approves, edits or rejects every change. Approved changes are published with automatic rollback.

Who it suits. Lean B2B marketing teams, roughly one to five people, on sites with modest traffic, starting in the UK. It is not available to buy yet. If you need a tool today, one of the products above is the better fit.

Pricing. The plans we expect to offer at launch are Starter at £199 a month, Growth at £499 a month and Scale from £1,250 a month, excluding VAT. There is nothing to buy today (pricing).

How to choose: five questions

Who should decide what goes live? If brand, legal or sales need to see every change, choose a tool where a person approves each one. If you are comfortable letting an algorithm choose between versions you have already approved, AI traffic allocation is an option.
Do you have the traffic? A/B tests and AI allocation need many conversions to learn from. A page converting 2% of visitors needs about 21,000 visitors per variant to detect a 20% relative improvement with conventional settings (our calculation, reproducible with Evan Miller's calculator¹⁵). If you have far less, favour tools that measure before and after and say when a result is inconclusive.
Will you move your website? Platform tools such as Optise change where your site is hosted and edited. Script-based tools leave your CMS as it is.
Do you want a tool or a service? Coframe describes itself as expert-managed; Varify is a tool your team operates.
Is the price published, and what drives it? Varify and Webflow publish prices, the latter tied to page views. Optise, Fibr and Coframe ask you to talk to them. Ask every vendor how the price changes as your traffic grows.

Questions to ask any vendor

Can I see and edit every change before it is published, and is each decision recorded?
How do I undo a change, and does anything roll back automatically if a page breaks?
How do you measure a result, and what do you report when there is not enough traffic to tell?
Does your script affect page speed or Core Web Vitals, and how?
Do search engines and visitors see the same content during a test?
What visitor data do you collect, where is it processed, and will you sign a data processing agreement?
What happens to my site and my data if I stop paying?

Where Artiweave fits

Artiweave is built for teams who want every change approved and every result reported plainly, on the site they already have. It is in private beta, with a waitlist and design partner places.

Frequently asked questions

What is the best AI website optimisation tool for a B2B company?

There is no single best tool. Choose by how your site is built, how much traffic it has and who should decide what goes live. Teams with plenty of traffic who want to run tests themselves may suit an A/B testing tool such as Varify; teams on Webflow may suit Webflow Optimize; teams who want a managed service may suit Coframe; teams willing to move their site to a new platform may look at Optise.

Do AI website optimisation tools publish changes automatically?

It varies. Optise, Fibr and Coframe each say on their sites that you approve changes before they go live. Webflow Optimize describes AI that decides in real time which audiences see which variant you created. Varify runs the tests you start and lets you roll out a winner with one click.

What happened to Intellimize?

Webflow acquired Intellimize in April 2024. Intellimize.com now redirects to Webflow Optimize, which Webflow describes as experimentation, personalisation and AI optimisation that works whether or not your site is built on Webflow.

Is Mutiny still a website personalisation tool?

Mutiny's own site now describes it as a sales assistant that drafts emails, proposals and other customer-facing assets. As of 3 November 2026 its homepage and pricing page do not describe website personalisation. A competing vendor says it stopped selling that product in April 2026; we could not confirm this from Mutiny's own site.
