How it works
PDF, DOCX or DOC. The AI reads the schedule of assessments and builds your visits, windows and draft forms.
Adjust questions in the visual builder, add edit checks and calculated fields, or start from templates.
Approve each form, then download the blank eCRF casebook for your ethics or IRB submission.
Sites enter data against the schedule. Monitors and data managers verify, query, freeze and lock fields as they go.
Protocol in
Upload the protocol and the AI Study Generator pulls out what it needs to build the study. A schedule-only upload is enough to create the visit skeleton, and you can add forms from the template library without sharing the full document.

Structure
The schedule matrix puts visits across the top and forms down the side. Tick a cell to collect a form at that visit. Site forms, participant questionnaires and ongoing logs are kept visibly apart, so the study plan is easy to review with your team.

Forms
Open any draft form to fine-tune it. Use AI to draft questions or a lab table from a description or a file, then add the validation that keeps the data clean.

Ethics submission
Ethics committees want to see the empty forms. Capture generates them from your approved CRFs as one PDF, so the document always matches what sites will actually use.

Live data
Once live, each field carries its own controls for queries, source data verification, freeze and lock. Every change is recorded field by field, with who, when and why.

Buyer checklist
Use this list when you compare tools. Here is how Capture handles each point.
Visual builder with AI drafting. Study teams build their own forms.
Edit checks on each field raise auto-queries as data is entered.
Template library with demographics, vitals, ECG, labs, AEs and more.
Draft and approved states, locked approved forms, field-level audit trail.
One-click blank eCRF PDF built from approved forms.
Free sandbox with nearly every feature and sample data.
Teams use anything from Word documents to enterprise EDC systems. Dedicated eCRF software such as Capture lets you design the forms, attach them to visits, validate data as it is entered and keep an audit trail, all in one place.
Yes. Upload the protocol as a PDF, DOCX or DOC file. The AI reads the schedule of assessments and related sections and drafts the visits and forms. You review and adjust everything before it is used.
A schedule of assessments on its own is enough to build the visit skeleton. You can then add forms from the template library or build them yourself.
A blank eCRF is the empty version of every case report form in your study. Ethics committees and IRBs often ask for it. Capture exports it as a PDF with a cover page, form index, visit by form matrix and every approved form.
Approved case report forms attached to the schedule, plus approved log forms such as adverse events. Drafts, archived versions and patient questionnaires are excluded.
Approved forms are locked for live use, and clinical data changes are recorded in a field-level audit trail with the user, time and reason. Clinical data is never hard deleted.
The AI produces a first draft in minutes. The time after that depends on how much you refine, but you start from a structured draft instead of a blank page.
Yes. The free sandbox includes nearly every feature and sample data, with no credit card.
