Capture vs Greenlight Guru Clinical: the short version
- Greenlight Guru Clinical, formerly SMART-TRIAL, is an EDC focused on medical device clinical investigations, from Greenlight Guru, which also offers quality management software for medtech.
- Device teams value EDC designed around ISO 14155 and post-market clinical follow-up.
- Capture supports custom device deficiency forms, AE and SAE workflows, and long follow-up with remote questionnaires.
- Teams using Greenlight Guru's quality system may value one vendor ecosystem; others prioritise study workflow.
- Test a device investigation and a follow-up schedule hands-on.

The comparison
Device investigations and post-market follow-up
Device studies have their own data: device identifiers, procedures, device deficiencies and device-related adverse effects, then years of post-market follow-up. A platform should make those structures easy and keep follow-up practical for participants who rarely visit a clinic.
In Capture, device fields and deficiency forms sit alongside the AE form with its minimum dataset, and follow-up questionnaires reach participants on their own phones with reminders. See ISO 14155 and EDC and post-market clinical studies.
What to compare
What to test when comparing Capture and Greenlight Guru Clinical
| Criterion | Why it matters | Capture |
|---|---|---|
| Device data | Deficiencies and device effects | Device deficiency and device relationship fields built in the visual builder |
| Safety workflow | Timely reporting | Routed safety alerts, SAE timeline, investigator sign-off |
| Follow-up | Years of post-market data | Remote questionnaires with windows and reminders |
| Study build | Time from protocol to testable study | AI drafts visits and forms from the protocol; your team reviews and approves |
| 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 |
This table shows Capture's answers only. Ask Greenlight Guru Clinical for theirs, and confirm current capabilities and terms directly with them.
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 Greenlight Guru Clinical fits, and when Capture does
Greenlight Guru Clinical is often a good fit for device companies already using Greenlight Guru's quality management system who want clinical data in the same ecosystem.
Capture fits device teams that want a self-serve build with AI drafting, participant ePRO and eConsent in the same study, and randomization for controlled investigations.
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 Greenlight Guru Clinical to Capture
Start the next investigation or follow-up study in Capture. Upload the clinical investigation plan for a drafted schedule and review the 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.
