Run Delphi studies your way: real-time or multi-round, with rich question types, comments, conditions and built-in analysis.



Choose the Delphi format that fits your study
Real-time Delphi
Participants see the group result right after they submit and can adjust their vote straight away. Best for fast, interactive studies.

Multi-round Delphi
Answers are collected per round. After reviewing the results, you start the next round, where participants see their own previous answer.

The right input for every question
Rating scales with flexible ranges, single and multiple choice, ranking, time estimates, percentage inputs and free-text metadata questions.
Let participants explain their answers
Enable comments on any question. Participants can give pro and con arguments, others can read and like them. You decide when comments become visible: never, after the first response, or always.

Show the right questions to the right people
Make pages, aspects and comments depend on earlier answers. Example: ask for a comment only if a participant answered “No” to the previous question. You can also restrict questions to participant groups.
