Capture vs TrialKit: the short version
- TrialKit, from Crucial Data Solutions, is an EDC platform known for its native mobile apps.
- Native apps can suit settings where staff work on dedicated devices; browser-based systems avoid installation and app store updates.
- Capture's participant questionnaires open from a secure link with no app, laid out for touch on phones and tablets.
- Capture does not currently offer offline data entry. If your sites have no connectivity, test offline needs with each vendor.
- Compare builds, participant tools and exports on your own protocol.

The comparison
Where will data actually be entered?
The mobile question is really about the setting. Site staff at hospitals usually have a desktop or laptop; home nurses and field researchers may use tablets; participants use their own phones. Apps can offer device features and offline use; browser-based tools remove installation, updates and app store accounts for every user.
Capture is browser-based. Questionnaires have large tap targets, keep the Next button above the keyboard, and survive a tablet being rotated mid-questionnaire. Participants open them from a secure link sent by email or SMS. See BYOD ePRO, no app download.
What to compare
What to test when comparing Capture and TrialKit
| Criterion | Why it matters | Capture |
|---|---|---|
| Device model | Installation and updates | Browser on phones, tablets and desktops; no app to install |
| Participant access | Onboarding friction | Secure link by email or SMS; no password to remember |
| Offline entry | Sites without connectivity | Not currently offered; confirm needs with each vendor |
| Study build | Time from protocol to testable study | AI drafts visits and forms from the protocol; your team reviews and approves |
| Modules in one study | Reconciliation and vendor count | EDC, ePRO, eConsent, randomization and kits with one audit trail |
| 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 TrialKit 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 TrialKit fits, and when Capture does
TrialKit may be the better fit if you specifically need native mobile apps, for example for data entry in places without reliable connectivity. Confirm the offline workflow with the vendor.
Capture fits studies where sites and participants are online and you want no apps to install, AI drafting from the protocol, and 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 TrialKit to Capture
Plan the move with a new study. Upload form specifications for the AI to draft, and send participants a secure link instead of an app download, updating participant materials accordingly.
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.
