Converts mixed-script Korean text containing hanja into hangul-only output, powered by the bundled Standard Korean Dictionary.

Processes plain text, HTML fragments, and Markdown (CommonMark and GFM). Supports hangul-only, parenthetical, and ruby markup rendering modes.

Load domain-specific vocabulary in FST or CDB format alongside the bundled dictionary to handle specialised terminology.

Force or suppress annotations for specific characters or glob patterns, inline or via a directives file.

Use from the command line, embed in a Rust crate, or run in browsers, Node.js, Deno, and Bun via WebAssembly or a native Node.js addon.

Process arbitrarily large documents chunk by chunk with a TransformStream interface in JavaScript or an iterator API in Rust.
