The Problem

Tests take too long.
And cost too much.

Idea → Briefing → Design → Dev → QA → Launch: Weeks pass before a single A/B test goes live. Every test requires developer capacity — and without AI support, this quickly becomes expensive.

Avg 2–4 weeks per test

From initial briefing to go-live takes weeks. Hypotheses gather dust in the backlog because manual implementation is too complex — this is exactly where AI-powered A/B testing comes in.

Expensive due to dev dependency

Every test needs developer resources — whether for frontend changes, QA or deployment. This costs time and money that's needed elsewhere.


Prompt Based Experimenting

Describe your hypothesis.
The AI builds the test.

Formulate your idea in natural language — the AI creates a testable variant that you can iteratively adjust via prompt. When needed, you have direct access to the generated JavaScript to save developers time.

1

Formulate prompt

Describe your idea in natural language — no technical details needed, the AI understands your optimization idea immediately.

2

AI creates the variant

Varify generates a variant including code. You can iteratively refine via prompt — or switch directly to JS.

3

Experiment starts immediately

Review, approve, go live — your AI-generated experiment runs in under 2 minutes. GA4 tracking is automatically configured.

AI CRO Audit

Your site, AI-analyzed.
Priorities delivered immediately.

Varify automatically scans your most important pages for conversion barriers — and delivers a prioritized list of optimization points, directly as testable hypotheses for Prompt Based Experimenting.

Instant hypotheses

Every finding is a testable hypothesis — one click starts the experiment directly via Prompt Based Experimenting.

10,000+ test patterns

The AI recommendations are based on CRO patterns from real experiments — not generic tips.

Prioritized by impact

Severity + estimated CVR uplift — you immediately know which test to start first.

Example: Audit report for my-shop.com/product/premium-sneaker
Critical

CTA below the fold on 68% of mobile devices

Der „Add to Cart"-Button ist auf den meistgenutzten Viewports (375×667, 390×844) nicht ohne Scrollen sichtbar. Sticky CTA oder Position-Shift testen. Potenzial: +12–18% Mobile CVR.

Critical

No trust signal in buy-box area

Neither quality seals nor review count are placed in the visible purchase area. Test Trusted Shops badge + star snippet directly next to price.

Medium

No urgency element despite limited product

Product name contains "Limited Edition", but availability and remaining quantity are not communicated. Test stock display or countdown.

Medium

CTA button contrast below WCAG AA on mobile

Blue button (#2563eb) on light background — contrast ratio 3.8:1 instead of min. 4.5:1. Test darker tone or larger font.

Optimization

Product images without zoom on desktop

High-resolution images available, but no hover zoom or lightbox activated. For fashion products, zoom increases dwell time by avg 15%.
