From idea to live experiment in minutes

Describe your marketing goal. Get structurally distinct copy variants with phrase-level emotion analysis. Ship the A/B test. Measure what wins and why.

Start experimenting See how it works

Xaiku dashboard showing variant generation and emotion analysis

Creating quality A/B test variants is slow, subjective, and fragmented

Write copy

AI copywriters give you rewrites, not structurally different angles. Your variants end up too similar because you anchor on the first draft.

Test it

A/B testing tools handle delivery but leave variant creation entirely to you. Setup across tools takes longer than the test itself.

Analyze results

You know variant B won. You don't know why. No insight means no compounding learning across experiments.

Xaiku replaces three disconnected tools with one.

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

Describe

Tell the AI what you're marketing. It asks the right questions and builds your experiment.

Generate

Get structurally distinct variants — not rewrites. Different angles, hooks, emotional appeals.

Refine

Phrase-level editing with emotion analysis, gene type classification, and voice controls.

Forecast

AI scores variants on 5 dimensions before you go live. Know the likely winner.

Ship & Measure

Integrate with one SDK call. Statistical validation tells you the winner — and why.
