AI A/B Test Runner
A platform that lets you create A/B tests for landing pages and emails with AI-generated variants, automatic traffic splitting, and statistical significance detection.
Moat
The Prompt
Build an A/B testing platform where users create tests with a control and variant. Include AI-generated variant copy suggestions for headlines and CTAs. Split traffic 50/50 via a JavaScript snippet. Track conversion events and display real-time results with confidence intervals. Auto-declare a winner when statistical significance is reached (p < 0.05). Use React with a Node.js backend and proper experiment assignment logic.
What You Can Build
- ✓Create test with control and variant URLs or HTML snippets
- ✓AI-generated variant headlines and copy suggestions
- ✓Traffic splitting (50/50 or custom ratios)
- ✓Conversion event tracking (click, signup, purchase)
- ✓Real-time results dashboard with confidence intervals
- ✓Automatic winner declaration at statistical significance
What's Hard
- ✗AI-generated variants are only as good as the input context. Statistical significance requires sufficient traffic — small sites may wait weeks for conclusive results. Cookie-based assignment can be affected by ad blockers.
What You Lose
- −Verify traffic splitting is truly random
- −Test conversion tracking accuracy
- −Validate statistical significance calculations
- −Ensure snippet works across different site architectures
