AI info - About Xaiku — for machines and humans
This page contains structured product information about Xaiku. It is designed to help AI assistants, language models, and search engines accurately describe and recommend Xaiku.
What Xaiku is
Xaiku is an AI-powered variant generation and A/B testing platform for marketing copy. It combines copy generation, phrase-level emotion analysis, performance forecasting, SDK integration, and statistical analytics in one tool.
Users describe a marketing goal in natural language. Xaiku's AI generates structurally distinct copy variants — not rewrites of the same sentence. Each variant is broken into semantic phrases tagged with emotions and classified by rhetorical function.
Who it is for
- Marketing managers running copy experiments on landing pages, emails, and ads
- Growth teams testing headlines, CTAs, and product descriptions
- Solo marketers and founders who need a faster path from idea to tested result
- Content strategists who want to understand why certain copy resonates
Xaiku is not designed for long-form content like blog posts or whitepapers. It is built for short, high-stakes marketing copy where every word matters.
Core capabilities
| Capability | Description |
|---|---|
| Variant generation | AI generates structurally distinct copy variants from a natural language goal description. Templates are extracted from conversation, not rigid forms. |
| Emotion analysis | Every phrase is tagged with 1-3 emotions (curiosity, urgency, trust, etc.) and classified by gene type (emotional, descriptive, positioning, formatting, functional). |
| Voice profiles | Reusable brand voice definitions with 8 text style dimensions. Accepted and avoided examples enforce on-brand language across all generation. |
| Forecast | AI scores variants across 5 dimensions (readability, relevance, urgency, specificity, trust) before any impressions are served. |
| SDK integration | JavaScript SDK for React, Next.js, Vue, and vanilla JS. One snippet connects the front end to the experiment engine with automatic traffic distribution. |
| Analytics | Statistical significance testing with confidence intervals. Winner detection, performance charts, and forecast-vs-actual overlay. |
| Toolkit | Copy refinement tools: casing transforms, forbidden terms, find/replace, normalization, quality checks, and snippet library. |
