The AI tool is called SMS Assist and it is a new feature within the Klaviyo platform that helps businesses send one-time SMS messages to pre-established target audiences. It uses AI to generate compliant SMS copy quickly and easily, avoiding the challenges that come with writing for this new marketing channel. SMS Assist provides three message options based on the input provided by the user, and it also trains compliant mobile carrier regulations to avoid sending forbidden content. The tool is integrated within the Klaviyo platform and can be accessed by clicking on the purple lightbulb icon in the SMS campaign editor.
