Capture vs iMedNet: the short version
- iMedNet is the eClinical platform from MedNet Solutions, including EDC.
- iMedNet is used by sponsors and CROs across drug and device studies.
- The key differences to test are build ownership, amendment speed and which modules sit in the same study.
- Capture drafts the study from the protocol with AI and locks approved forms, so amendments are deliberate and recorded.
- Capture supports device studies, with custom device deficiency forms and long post-market follow-up.

The comparison
Build ownership and amendments
In some eClinical models the vendor or a services team builds the study; in others the sponsor does. Neither is wrong, but they lead to very different amendment experiences. When a protocol changes, who makes the change, how long it takes and what it costs decide how painful mid-study changes are.
In Capture, your team makes the change in the visual builder, tests it, and approves it. The audit trail records what changed. For device studies, see ISO 14155 and EDC and EDC for medical device trials.
What to compare
What to test when comparing Capture and iMedNet
| Criterion | Why it matters | Capture |
|---|---|---|
| Build ownership | Speed of builds and changes | Your team builds; AI drafts from the protocol |
| Amendments | Traceable changes | Draft and approved states; approved forms locked; changes recorded |
| Modules in one study | Reconciliation and vendor count | EDC, ePRO, eConsent, randomization and kits with one audit trail |
| Device studies | Deficiencies and follow-up | Custom device deficiency forms; long follow-up with remote questionnaires |
| Compliance controls | Part 11 and GCP expectations | Field-level audit trail, re-authenticated e-signatures, role-based access |
| Commercial model | Fit for your study size | Free sandbox; no setup fee; pay only when you go live |

Self-serve build
Your team builds and amends, with AI doing the drafting
The AI form builder drafts questions or lab tables from a description or an uploaded file, and the AI Study Generator drafts the schedule from your protocol. Nothing is saved without human review. Forms move from draft to approved and are locked for live use, so amendments are deliberate and recorded.
- Ten question types plus repeating table sections.
- Calculated fields such as BMI, BSA, eGFR and QTc.
- Configuration export and import between studies.

One platform
EDC, ePRO, eConsent and randomization in one study
Sites enter data on locked, approved forms with edit checks that raise queries at entry. Participants complete questionnaires on their own phones and sign eConsent with verified signatures. Randomization and kit management run in the same study, and everything shares one field-level audit trail.
- One participant record across every module.
- No integrations to build or reconcile.
- Phase 1 through Phase 3.

Fit
When iMedNet fits, and when Capture does
iMedNet is often a good fit for teams with existing iMedNet studies and processes, and for organisations that prefer the vendor's build and support model.
Capture fits teams that want to build and amend studies themselves, with AI drafting, and run EDC, ePRO, eConsent and randomization in one study.
Compliance controls
The controls inspectors look for, built in
Every change is written to an append-only, hash-chained audit trail with user, time, old and new value and reason. Electronic signatures require password re-authentication and carry a meaning statement. Roles separate sites, and identifying data is segregated from study data at the database layer.
- Field-level audit trail, never hard deleted.
- Re-authenticated e-signatures.
- Role-based access with site separation.

Switching
Moving from iMedNet to Capture
Start new studies in Capture with AI-drafted builds from the protocol or your existing specifications. Use the template library for standard forms.
Historical data stays in its original export and is combined at analysis if needed. See how to switch EDC vendors mid-study for when a mid-study move makes sense.

Every comparison uses the same approach: what to test, where each option fits, and Capture's own answers. See all of them on the comparisons hub at /compare.
Is Capture an iMedNet alternative?
Yes, for teams that want a self-serve build with AI drafting and EDC, ePRO, eConsent and randomization in one study.
Does Capture support medical device studies?
Yes. Build device and deficiency forms alongside the AE form and SAE workflow, with long post-market follow-up.
Who makes amendments in Capture?
Your team, in the visual builder. Approved forms are locked and changes are recorded in the audit trail.
Can I test Capture before deciding against iMedNet?
Yes. The free sandbox includes every feature with sample data, no credit card and no time limit. You pay only when you go live.
How did you build this comparison?
