Start your trial design

Load a worked example to see how it works, or start from a blank canvas. The tool builds your study diagram and a schedule of assessments table you can export into a protocol.

Continue a saved design

Drop in a PNG you saved earlier — every Save as PNG download also stores your design, so you can rebuild it exactly and carry on editing.

Choose a file or drag it here

On a phone, save the file to Files (not Photos) so your design is kept — or just use the share link from the review screen.

Study population

Describe the population for your trial.

Randomisation

How participants are allocated across arms.

Trial arms

Add each arm of your trial — the intervention, a short description and the number of patients.

Arm name Description (intervention, dose…) n

Study activities

Your schedule of assessments — each activity and the day it occurs. Details appear in the table only, not on the diagram.

Activity name Day Details (table only)
