About ClinicalTrials.Tools
We're building the modern platform for clinical trial design — making validated statistical tools accessible to every researcher.

Clinical trial design shouldn't require expensive enterprise software or years of biostatistics training. ClinicalTrials.Tools democratizes access to validated sample size calculators, power analysis tools, and AI-driven design guidance — helping investigators worldwide design better trials, faster.

Every calculator is validated against published reference tables and peer-reviewed formulas. We show our work.

Beautiful, intuitive interfaces that work on any device. No Java applets. No desktop downloads.
Built for Researchers
Designed with input from PIs, biostatisticians, and CRAs at leading academic centers.
Scientifically Rigorous
Our statistical engine uses exact distributions and methods from peer-reviewed publications.
