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 your form, let AI build it
Describe the form you need in plain language and Makeform drafts the questions, structure, copy and logic automatically.
Combine payments, signatures, file uploads, ratings, rankings, matrices, dates and calculated fields in one form.
Build conditional branching, variable-based calculations, hidden fields for URL parameters and answer piping for personalised forms.
Start from ready-made templates for feedback, intake, registration, quizzes, surveys and more instead of building from scratch.
Offers more advanced multi-page logic and database integrations, but requires slightly more setup than quick prompt generation.
Features a broader traditional drag-and-drop builder with solid AI drafting, though less centered on pure chat generation.

Great for lead-generation quizzes and polls, but less flexible for deep backend database form connections.
