IntelliJ IDEA helps you check that all text written in natural languages is correct. This works similar to coding assistance, but instead of incorrect programming language syntax, the IDE detects and highlights typos, spelling mistakes, grammatical errors, stylistic complexity, and so on. Besides common text files, such as your project's README.md, it can check text in your source files as well: names of classes, methods, fields, and variables, string literals, comments, JavaDocs, and even your commit messages. For more information, see Scope of grammar checks.
By default, IntelliJ IDEA includes English language support. If you open a file with several paragraphs of text in another supported language, IntelliJ IDEA will detect it and show a suggestion to download and enable checks for this language. You can see the list of supported languages and enable them in the settings.
