Detailed Review
Ledidi is the only tool in this list that publishes euro prices on a pricing page, although trial functions are added through a calculator on top of a base plan. The legal entity is Ledidi AS in Oslo, enterprise number 917 137 137.
Norway sits in the EEA, so the contracting entity meets the European rule even outside the EU.
Starting from the protocol
The AI Study Builder drafts a study structure from an uploaded protocol, and the team reviews and edits the result. The site markets this as study setup without programmers.
Design Mode testing is free until the project goes live, which lets a team judge the build before paying the startup cost.
Registries as well as trials
Ledidi Core and Ledidi Admin cover registries and governance, so the same vendor can serve a clinical trial and a long-running registry. That breadth suits hospital departments with both needs.
Hosting in two regions
Data is hosted in the AWS Frankfurt region with backups replicated to Stockholm. The site adds that the platform is built on confidential computing with end-to-end encryption.
Limitations to Consider
Trial pricing is not a single number, since features are priced per project through a calculator plus a one-time startup cost. Hosting runs on AWS, and the pages checked do not state who owns Ledidi. Ledidi lists no CTMS or eTMF, so large multi-country operations will want BSI Life Sciences or Viedoc alongside it.
Who Should Use Ledidi
Investigator-led studies, hospital research groups and small CROs that want transparent entry pricing and an AI-drafted study build.
