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.
Turn any text, PDF or video into an interactive quiz
Turn pasted text, PDF files or video transcripts into a full quiz in a single pass, then edit or discard any question.
The tool adjusts question type and difficulty to the learner's level, so assessments fit different audiences.
Ask questions in the languages your learners, staff or customers actually use.
Add images, video and charts to questions instead of relying on plain text.
More advanced layout customization and database integrations, but lacks client-side end-to-end data encryption features.
