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.

Describe the form you want in natural language and Nexform builds the complete structure, fields and validation rules automatically.
Every published form comes with a shareable short link plus a generated QR code, so it works online and in physical locations.
Intelligent field validation prevents bad submissions, while dynamic fields adapt based on earlier answers to keep forms relevant.
