A/B Testing on Autopilot

From conversational prompt to statistically valid winning variant in three simple steps.

1

Prompt Your Agent

Tell Kopair in plain words what you want to test: "Move this section higher", "Test a 2-step lead capture flow", or "Rewrite the copy to target enterprise CTOs".

2

Zero-Code Variant Launch

Kopair generates the changes and serves them instantly via a lightweight 4KB edge snippet. Zero layout flicker, zero engineering tickets, and no slow load times.

3

Automated Stat-Sig Winner

Our Bayesian engine watches conversions in real-time. As soon as a variant achieves statistical significance, you get alerted and can auto-promote the winner to 100% traffic.

Built for Modern Growth Teams

Everything you need to turn website optimization from a month-long slog into a 5-minute task.

💬

Natural Language Editor

Edit text, rearrange components, change colors, and swap imagery simply by typing what you envision.

📊

Bayesian Math Engine

Stop guessing sample sizes. Real-time Bayesian probability curves ensure you only implement real winners.

⚡

Zero Flicker Delivery

Custom anti-flicker technology ensures your visitors never see awkward content jumps or delays.

🎯

Multi-Goal Tracking

Track revenue, signups, button clicks, scroll depth, and custom JS webhook conversions effortlessly.

🔄

Auto-Traffic Shifting

Multi-armed bandit algorithms route traffic dynamically toward winning variations to protect your revenue.

🔌

Universal Compatibility

Drop into Next.js, Webflow, Shopify, WordPress, Nuxt, Astro, or any custom stack with 1 script tag.

Frequently Asked Questions

Everything you need to know about Kopair and our upcoming beta launch.

Traditional tools like Optimizely or VWO require complicated visual point-and-click builders or engineering resources to code variants. Kopair is agentic: you instruct an AI agent conversationally (e.g. "Move the testimonial block above the pricing table, change CTA copy to 'Start Free', and swap hero images"), and the agent writes and executes the DOM mutations automatically.

Not at all! Anyone on your marketing, product, or founder team can run high-impact experiments. You simply describe the change in plain English, preview the variant live, and hit publish.

No. Kopair uses an ultra-lean 4KB CDN script with asynchronous hydration and zero layout shifts. Search engine crawlers receive the original canonical markup without interference, preserving all your search rankings.

Kopair applies Bayesian probability models that continuously estimate the true conversion rate distribution of each variant. You get a clear probability score (e.g. "99.4% confidence that Variant B outperforms Variant A") so you never stop an experiment prematurely or declare a false winner.

We are currently onboarding early-access partners in private batches. Sign up on the waitlist above, and you will receive an invitation link and priority onboarding access.
