In their own words
GitHub Copilot
GitHub Copilot provides contextual assistance across software development, including inline code suggestions, chat, code explanations and answers to documentation questions. It works on GitHub and in editors including Visual Studio Code, Visual Studio, Xcode, JetBrains IDEs, Vim, Neovim, Eclipse and Azure Data Studio; GitHub Mobile supports Android and iOS. Copilot CLI is included with all plans, and the tool can index codebases and work with terminals. Agent workflows can launch work from GitHub, track agents, review changes and merge completed work. The Free plan gives eligible individual developers 2,000 code completions and 50 chat requests per month, with community support; eligibility excludes people with organizational or enterprise Copilot access. Pro costs $10 a month, Pro+ $39 a month and Max $100 a month. Business is $19 seat per month, and Enterprise is $39 seat per month. Paid plans have unlimited code completions, while chat, agents, code review, CLI and Copilot Apps consume GitHub AI Credits. Suggestions are probabilistic; models are trained on natural language and publicly available source code.
