The Build screen

Build is where you author your screener and your question guide, with an AI assistant to help, all on one screen.

Build is where you design your study. It has three panels:

  • Guide (left): the tree of every step in your screener and question guide, in the order participants will encounter them.
  • Properties (center): the editor for whatever step you click.
  • Assistant (right): an AI build assistant that can read your draft and help you edit.

The Build screen's three panels: the Guide tree (Screener and Interview) on the left, the Properties editor in the center, and the Assistant panel on the right.

How it works

The Guide panel has two regions:

  • Screener at the top: pre-interview questions that decide who qualifies.
  • Question guide below: the steps the AI moderator will run with anyone who passes the screener.

Click + Add element in either region to insert a new step. Click any existing step to open it in Properties.

A small bar at the top of Build shows your study's status (draft, live, closed), a Preview button, and a Publish button. To leave Build, switch between Build → Recruit → Results at the very top of the page.

Things to know

  • You're always editing a draft. Changes only go to participants when you click Publish.
  • The Assistant panel reads both the screener and the question guide. You can ask it about either.
