Discover instruments, request a licence, build a modular study, collect responses and get scored, analysis-ready data — without a single email to an instrument author.
Every instrument is a first-class asset with authors, DOI, version, licence and scoring.
Official instrument items, wording, response options and reverse coding are locked. Researchers place them, never edit them.
Each instrument carries its own licence model. Academic-free instruments auto-approve; the rest route to the owner's inbox.
Compose consent, demographics, official instruments, custom questions and a debrief in any order.
Sum and mean scores per subscale with reverse coding applied server-side the moment a participant finishes.
Wide-format CSV and JSON with stable variable codes and a variable dictionary for every study.
Every study records the instrument version, translation set and scoring rules that produced its data.
