AI conversion optimization for Shopify and WooCommerce that lifts CVR 3.4x.
Shopify's platform default storefront conversion is 1.4%. Zubby stores average 4.8%. The gap is bandit-tested opening messages, margin-aware offers, and an AI agent that handles the questions a static PDP can't. Flat monthly pricing — no per-resolution fees, no surprise bills.

What is AI conversion optimization?
AI conversion optimization is the practice of running continuous, automated experiments on the shopper-facing surfaces of your store — opening messages, offers, bundles, follow-up questions, recovery email copy — and letting an algorithm route traffic to the highest-converting variant in real time. Zubby uses Thompson sampling, a multi-armed bandit method, so you don't burn weeks of traffic on losing variants waiting for statistical significance.
Where classic CRO depends on rare hero tests, Zubby turns optimization into a steady drumbeat: dozens of small tests running in parallel, winners promoted, losers retired, and a continuously rising conversion baseline. The agent itself is part of the surface under test — an AI that can answer the question a static PDP can't is, structurally, a conversion lever in a way no popup or upsell app is.
Across 14,000+ Zubby stores, that combination — bandit testing plus AI agent — averages a 4.8% storefront conversion rate, against a Shopify platform default of 1.4% and a Tidio benchmark of 2.1%. Pricing stays flat per tier — one predictable monthly price, with no per-resolution AI metering.
From hypothesis to lift in days, not months.
Three steps from install to first promoted winner. See the bandit testing feature or the Shopify install guide.
Define variants
Spin up an opening-message test, an offer-ladder test, or a bundle-composition test. The dashboard suggests what's worth testing for your current traffic level.
Bandit routes traffic
Thompson sampling pushes more traffic to high-performing variants from session one. No test-and-pray, no two-week traffic tax.
Promote winners
Variant hits 95% posterior probability of beating baseline — auto-promoted with a 14-day novelty freeze for safety.
The CRO stack, built in.
Bandit testing, AI variant generation, honest stats, and revenue attribution — wired together so you don't bolt three tools onto your storefront.
Bandit-driven tests
Thompson sampling on every test, with configurable priors and confidence thresholds.
Auto-promotion
Winners ship themselves once they cross the configurable significance threshold. No copy-paste, no merge conflicts, no missed wins.
Honest reporting
95% credibility intervals, expected lift, expected revenue impact — no p-value cargo cult, no dashboard maths that doesn't reconcile.
Novelty freeze
After a winner ships, a 14-day measurement window catches regression and reopens the test if needed.
AI variant generation
Stuck for ideas? The agent proposes high-leverage variants based on your traffic, current performance, and category benchmarks.
Parallel orthogonal tests
Run multiple tests at once — the engine accounts for interaction effects automatically. Sequential tests resume from the prior, not from zero.

Without Zubby
- Designer wrote a witty greeting. Nobody tested it.
- Six months of 'Hi! How can I help?' — same conversion baseline.
- Quarterly CRO retro: no high-confidence wins this quarter.
- Nobody knows why.
With Zubby
- ZubbyTest live: 4 opening messages, traffic routed by bandit.
- ZubbyDay 3: Variant C ('What brought you here today?') at 62% best-arm probability.
- ZubbyDay 7: Variant C promoted. +11% conversion lift, 95% credibility interval [+6%, +16%].
- ZubbyDay 21: Novelty freeze cleared. Lift held at +10.4%. Next test queued.
