ABOUT

Built by R users, for R users

We got tired of asking R questions and getting Python back. RCode.ai is the assistant we wanted in grad school and in industry.

RCode started as a side project: a tuned system prompt and evaluation suite focused on tidyverse, ggplot2, Shiny, and biostatistics. The goal was not another general chatbot with an R mode — it was an assistant that could pass a code review from an experienced R developer.

Today we serve analysts in academia, CROs, pharma, and data journalism. Our playground is free for 30 messages a day because we believe you should be able to evaluate quality before paying.

Principles

  • Runnable R first — complete examples, not fragments
  • No training on customer code or prompts
  • Transparent usage limits — no surprise bills
  • Honest about uncertainty — we cite package docs when specs matter
