Evaluation criteria
Use the same list whichever vendors you shortlist alongside Viedoc.
Capture: yes, a free sandbox with every feature and sample data.
Capture: EDC, eConsent, ePRO and randomization share one platform and one audit trail.
Capture: pricing scales with study size rather than a fixed enterprise contract.
Capture: field-level audit trail, OTP-verified e-signatures, role-based access.
Capture: AI-assisted study builder, no vendor change-control cycle for routine edits.
Switching
Migrating between EDC systems usually means recreating every CRF by hand. Capture's AI drafts forms and lab tables from a description or an uploaded file, and the template library covers the standard forms most studies already use.

Data quality
Whatever system you move to, you need validation rules and a real audit trail from day one. Capture lets you set edit checks yourself, with auto-queries raised the moment a value breaks a rule.

Sponsors and CROs actively comparing EDC vendors, including teams currently using or evaluating Viedoc, who want an option with integrated eConsent and ePRO and a self-serve way to test the system first.
Whether you can test the full system before a sales call, whether eConsent and ePRO are integrated, how pricing scales with study size, and what Part 11-aligned controls and validation documentation are available.
Yes. Capture provides a field-level audit trail, OTP-verified electronic signatures and role-based access control, with documentation to support sponsor validation when required (Enterprise).
Yes. The free sandbox includes every feature with sample data, no credit card and no time limit, so you can test it against your own protocol before deciding.
It usually does elsewhere. Capture's AI drafts forms and lab tables from a description or file, and the template library covers standard forms, so you are not starting from a blank page.
