LingoTweaker

A language checker in WebAssembly. Everything runs in your browser; the text never leaves the page.

Language Check as you type loading engine…

Right-click an underlined word for suggestions (or tap it on a touch screen). Underline colour by issue type: misspelling, grammar, style, typographical, duplication, other.

Engine: LingoTweaker (Rust + WebAssembly), a JVM-free grammar and spelling checker.

Rules

Include picky rules

Toggling rules recompiles the engine in the worker; the data pack is reused, so nothing is downloaded again.
