Stat-Assist is designed to make clinical research design, analysis, and reporting friction-less for clinicians. The platform guides users through the process of designing studies, selecting appropriate statistical tests, calculating required sample sizes, and generating study protocols.
- Study Design Wizard: Step-by-step guidance for designing various study types (RCT, Diagnostic Accuracy, Cohort)
- Statistical Test Recommender: Automated recommendations for appropriate statistical tests based on study design and variables
- Power Calculator: Interactive sample size and power calculations with visualizations
- Protocol Generator: Automated generation of study protocols based on design inputs
- PICOT Refiner: Converts free-form questions into structured PICOT format using Gemini Flash
- Backend: FastAPI, SQLAlchemy, PostgreSQ
- Frontend: React (Next.js), Tailwind CSS, shadcn/ui
- aat engine
- Deployment: Kubernetes-ready

Clone the repository:
git clone https://github.com/your-org/stat-assist.git cd stat-assist -
Install dependencies for all services:
npm run install:allThis will install:
- Python dependencies for the API service
- Python dependencies for the PowerSim service
- Node.js dependencies for the UI service
-
Set the
GEMINI_API_KEYenvironment variable with your Gemini Flash API key. This is required for the research question refinement features.
Start all services with a single command:
npm start
This will concurrently run:
- Backend API at http://localhost:8000
- Frontend UI at http://localhost:3000
- PowerSim service at http://localhost:8001
For development, you can run each service individually:
# Run only the backend API
npm run start:api
# Run only the frontend UI
npm run start:ui
# Run only the PowerSim service
npm run start:powersim
For demonstration purposes, you can use the "Demo Login" button on the login page. This will give you access to the platform without requiring registration.
