Privacy-first AI surveys with end-to-end encrypted responses
Responses are encrypted on the respondent's device before upload, so only the survey owner holds the key and can decrypt the data.
Generate structured, less biased questionnaires from a prompt, refine wording, create answer options and add skip logic and multilingual support.
Automated thematic analysis, sentiment detection, anomaly flagging and data encoding turn open-ended answers into usable categorical insight.
Run natural back-and-forth interviews with dynamic follow-up questions that adapt to each respondent for deeper qualitative data.
