Tripetto

Tripetto is a form and survey builder that emphasizes conversational, adaptive experiences. Questions branch based on previous answers, and the interface feels more like a chat than a traditional form. You can build in the web-based studio, embed as a plugin into WordPress, or use the SDK in custom applications.

The conversational approach tends to boost completion rates for longer surveys. If you want respondents to feel like they're having a dialogue rather than filling out a form, Tripetto's logic-driven branching and friendly interface make that possible. The multiple deployment options mean you can use it almost anywhere.
