TLDR JetBrains
JetBrains IDE plugin that explains selected code in plain English, making unfamiliar codebases and complex expressions easier to understand.
About
TLDR is a plugin for JetBrains IDEs that takes any selected code, from a single regular expression to a multi-line function, and returns a clear English-language explanation without leaving the editor. It is particularly useful when navigating an unfamiliar codebase, decoding SQL queries, or understanding complex logic written by someone else. A free tier allows a limited number of explanations per day. Paid individual and team plans remove that daily cap and raise the maximum code length that can be submitted at once.
