The short version

  • Only Elicit has a free tier, so it costs nothing to try first.
  • Each has a real cost: Elicit pro and Scale plans available at different monthly prices; annual billing options not specified; REDCap a for-profit company cannot hold a licence or self-host REDCap, so a biotech or CRO that liked it at university simply cannot deploy it the same way and must buy a commercially licensed hosted version instead.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Elicit

  • Pro and Scale plans available at different monthly prices; annual billing options not specified
  • Enterprise plan pricing not disclosed; requires contacting vendor

REDCap

  • A for-profit company cannot hold a licence or self-host REDCap, so a biotech or CRO that liked it at university simply cannot deploy it the same way and must buy a commercially licensed hosted version instead.
  • Because each institution hosts its own instance, support, uptime, backup and version currency vary by university, and a researcher has no recourse to Vanderbilt when the local instance is two years out of date.
  • It is free of licence fee but not free of cost: the hosting institution carries server, security, patching and support staffing, which is why some institutions charge internal recharges per project.
  • Validation for regulated use is the deploying institution responsibility, so an instance is not Part 11 compliant simply because REDCap supports the features; someone locally has to produce and maintain the evidence.
  • The interface and reporting are dated compared with commercial survey and EDC tools, and complex logic is built through data dictionary spreadsheets rather than a modern visual builder, which slows non technical study teams.

REDCap: Is REDCap really free?

The licence is free to non-profit institutions and government organisations that join the consortium, but they must host and support it themselves, so there is real internal cost.

Elicit: What is the difference between Elicit's Pro and Scale plans?

Elicit's Pro plan ($49/month) includes standard usage limits, dedicated screening of up to 5,000 papers, and access to 135 data sources. The Scale plan ($169/month) offers 5x higher usage limits, screening of up to 40,000 papers, figure extraction, team collaboration, and access to 200 data sources.

REDCap: Can my company use REDCap?

Elicit: What security features does Elicit Enterprise offer?

Elicit's Enterprise plan includes single sign-on (SSO), SAML, two-factor authentication (2FA), PRISMA-grade screening and extraction accuracy, and a dedicated customer success team. Pricing is custom and requires contacting the vendor.

Source
REDCap: Is REDCap 21 CFR Part 11 compliant?

It has the features to support Part 11 use, but compliance depends on how the hosting institution configures, validates and documents its own instance.

REDCap: Who supports it?

Your local institutional REDCap administrator, not Vanderbilt. Support quality varies by site.
