Phrasee

Phrasee (now part of Jacquard) specializes in generating and optimizing marketing language at scale. The AI creates on-brand copy for email subject lines, push notifications, SMS messages, social ads, and web content, then uses real-time experimentation to learn what resonates with each audience. The platform generates dozens of message variants and uses dynamic optimization to automatically shift traffic to top performers. Over time, the AI builds a model of your audience's language preferences, improving performance with each campaign. Phrasee's brand controls ensure every AI-generated message matches your tone, terminology, and compliance requirements. The platform is trusted by major brands including eBay, Walgreens, and Virgin, and reports average uplift of 2-10x in engagement metrics compared to human-written control messages.
