# SplitWisp

> SplitWisp is a lightweight visual A/B testing tool with a Chrome extension editor. It lets non-technical founders, marketers, and growth teams run experiments without developers.

## About

SplitWisp fills the gap left by Google Optimize (shut down September 2023). It provides a Chrome extension visual editor for creating A/B test variants by clicking on elements on your live site — no code, no deploy, no developer tickets. The SDK is ~5KB gzipped with sub-10ms variant assignment.

## Key Features

- Visual experiment editor via Chrome extension
- Lightweight JavaScript SDK (~5KB gzipped)
- Sequential statistical testing with configurable confidence thresholds
- UTM-segmented results (break results down by traffic source)
- Auto-promote winning variants
- Multi-armed bandit mode (Thompson Sampling) on Pro tier
- Sticky variant assignment via hashed session ID
