Key features
- No-code visual editor
- A Chrome extension opens your live store so marketers can swap copy, images, CTAs and whole sections visually, with rules that ship in seconds.
- AI Copilot
- It reads your page structure and copy, learns your brand tone and product details, then the CustomFeds ML engine generates the change and self-iterates until it is right.
- CRO Page Audit
- Scans a page across 7 dimensions and returns prioritized findings with a severity, lift estimate, effort level and one-click fix.
- Competitor PDP analysis
- Compares a competitor's product page against yours on copy, pricing, trust signals and layout, then returns a scored report with prioritized fixes.
- Funnel-wide testing
- Run theme-level, template-level, price, discount, shipping, content, split-URL and checkout gateway A/B tests from one platform.
- Audience targeting
- Build rules from 40+ built-in attributes such as geo, device, cart value, session count and inventory, and bring custom events from Segment, RudderStack or GA4.
- Bayesian analytics
- Segment-aware significance, revenue per visitor instead of CVR alone, and automatic pausing of losers and promotion of winners.
