1. Start a study
From Studies (or an Explore use-case card), click Start building. You get a blank draft and land in the Builder. To start from existing work instead, Replicate a public study from Browse or use a Library template.2. Add blocks
The Builder is a list of blocks — each is one screen or measure a participant sees. Add blocks from the picker: instructions, Likert scales, multiple choice, open text, stimuli (text/image/video/audio), timers, and more. See the block catalogue. Reorder by dragging. Edit a block’s wording and options inline. Everything autosaves as your Draft.3. Branch and compare (optional)
- Conditions show or hide blocks based on earlier answers — for screening, branching, and randomized arms.
- Variants define version-level arms (e.g. an A/B of two stimuli) so participants are split across versions.
- Themes control the look participants see.
4. Preview
Click Preview to take the study exactly as a participant would — one screen at a time, with live validation and branching. Nothing you do in Preview counts toward results.5. Make it runnable
To collect real data, freeze a version:- Publish — freezes a runnable version (good for pilots/exploratory work).
- Preregister — freezes a version and timestamps your plan on the OSF (the open-science path).
