btw

A complete toolkit for connecting R and LLMs

Overview

btw helps R users work with Large Language Models, whether you’re pasting context into ChatGPT, chatting with an AI assistant in your IDE, or building LLM-powered applications.

The challenge: LLMs need context about your R environment to be helpful—your data structures, the packages you’re using, relevant documentation.

btw provides a flexible toolkit that works across different workflows:

• Copy-paste to external LLMs: Quickly gather context from your R session and copy it to your clipboard for pasting into ChatGPT, Claude, or any other chat interface.
• Interactive chat in R: Launch a full-featured AI assistant directly in your IDE that can explore your environment, read documentation, and help you write code.
• Build LLM-powered tools: Integrate btw’s capabilities into your own applications, whether you’re creating custom chat interfaces or connecting R to coding agents.

Quick Start

Copy-paste workflow

Use `btw()` to gather context from your R session and copy it to your clipboard:

library(btw)

# Describe a data frame
btw(mtcars)

# Include package or function documentation
btw("{dplyr}", ?dplyr::across)

# Combine multi
