Natural languages
IntelliJ IDEA helps ensure your codebase is error-free and consistent not only in terms of correct programming languages syntax, but also in terms of proper grammar, spelling, and style. In addition to common text files like your project's README.md, it checks natural language consistency and correctness in your source files, including names of identifiers and variables, contents of string literals, comments, JavaDocs, and even your commit messages.
