RTutor

RTutor is a free artificial intelligence statistical programming assistant designed to accelerate data analysis for researchers, biostatisticians, and data scientists. By allowing users to upload CSV, Excel, or RData datasets and ask analytical questions in plain English, the platform automatically generates, tests, and executes R and Python code in real time. This immediate synthesis makes advanced statistical modeling accessible to non-programmers.

The system utilizes large language models fine-tuned on data science libraries such as tidyverse, ggplot2, pandas, and matplotlib. When a user submits an analytical query, RTutor interprets the underlying dataset structure, writes the corresponding statistical code, runs it within a secure cloud sandbox, and renders publication-ready plots alongside comprehensive explanatory notes. Users can inspect the raw code to learn best programming practices.

Accessible online via any modern web browser without requiring local R or Python installations, RTutor is completely free for academic and exploratory use. The platform allows researchers to export complete R Markdown documents, publication-grade graphics, and full reproducible research reports with a single click.
