Design events, pages and fields — and change them safely once patients exist
AI-assisted protocol extraction, a drag-and-drop event and field builder, and a structural-change workflow that shows the exact impact on existing patient data before you confirm it.
Request a demoDesign and capture share one model
A field defined in the study builder is not just a label — it is the object every captured field value points back to, across every patient and every visit.
Change the field definition and every downstream value stays traceable to it.
AI-assisted extraction
Upload a protocol PDF or a CSV/XLS/XLSX and get inferred fields and structure back in minutes, not a services engagement.
Impact-aware structural changes
A save that would orphan patient data returns a structured impact summary — patients, visits, forms, SDV and signatures affected — before anything is touched.
Derived fields with formula IntelliSense
Computed fields reference other fields across forms in the same event, with inline diagnostics while you write the formula, not after you save it.

Bring a protocol or an existing study and we'll show you what this looks like in Arion.
