What is TLDR?
TLDR is an IDE plugin that uses AI to explain code in plain English. Rather than spending time deciphering unfamiliar code, developers can select any snippet and get an instant explanation of what it does. The tool supports nearly all programming languages, including SQL and regular expressions, so it works across different tech stacks and scenarios. The plugin integrates directly into JetBrains IDEs, processing code on TLDR's servers to generate explanations. It's available in both free and paid versions; the free tier covers basic explanations, whilst paid plans remove limitations and add extra features. This makes it practical for individual developers who occasionally need code explanations as well as teams working regularly with unfamiliar codebases.
