Natural languages

Last modified: 20 March 2024

This section describes how to use a spellchecking plugin. To switch IntelliJ IDEA UI to another language, install and enable a corresponding language pack plugin. For more information about installing plugins, refer to Install plugins.

IntelliJ IDEA helps ensure your codebase is error-free and consistent, not only in programming languages but also in natural languages. The IDE includes a spell-checker for typos and spelling mistakes, and it also reports grammatical errors and stylistic problems. In addition to common text files like your project's README.md, it checks natural language consistency in your source files, including names of identifiers, contents of string literals, comments, JavaDocs, and even your commit messages.

By default, IntelliJ IDEA includes support for the English language. If you open a file with several paragraphs of text in another supported language, IntelliJ IDEA will detect it and offer a suggestion to download and enable checks for that language. You can see the list of supported languages and enable them in the settings.
