Xaiku dashboard showing variant generation and emotion analysis

Copy testing shouldn't take three tools

Write copy

AI copywriters give you rewrites, not different angles. Your variants end up too similar.

Test it

A/B tools handle delivery. Variant creation? Still on you. Setup takes longer than the test.

Analyze results

You know variant B won. You don't know why. No insight, no compounding.

Xaiku replaces three disconnected tools with one.

How it works - From idea to live experiment in five steps
