# Language support

> For the complete documentation index, see [llms.txt](https://www.jetbrains.com/help/air/llms.txt).

How much the editor understands depends on the language. For some languages you get code insight backed by a language server, including navigation such as Go to Definition, Go to Implementation, and Find Usages. For the rest, you get syntax highlighting only.

## Languages with LSP-backed support

For the languages in this section, an LSP server provides code insight. This can include navigation, completion, semantic highlighting, quick-fixes, rename, formatting, and related features.

| Language | Provider |
| --- | --- |
| Kotlin | Kotlin Analyzer (kotlin-lsp) |
| Go | gopls |
| Rust | rust-analyzer |
| Python | basedpyright (Python + PythonStub) |
| C, C++, CUDA | clangd |
| TypeScript and JavaScript family | TypeScript language server (JS, JSX, TS, TSX, Vue, MJS, CJS, MTS, CTS) |
| HTML | VS Code HTML LSP (HTML, HTM) |
| CSS family | VS Code CSS LSP (CSS, SCSS, LESS) |
| Svelte | svelte-language-server |

Java is not supported yet.

## LSP add-ons

Add-on LSP servers also run in supported file types. These servers extend specific features but do not define primary language semantics.

| Add-on | Where it works |
| --- | --- |
| Tailwind CSS LSP | HTML, Svelte, Vue, JavaScript, TypeScript, CSS, Sass, and related file types |
| Emmet LSP | HTML, CSS, SCSS, Sass, Less, JSX, TSX, XML, Vue, Svelte |
