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.
