grammachy
A grammar check that runs only when you ask
grammachy is an Omarchy plugin that checks grammar and spelling on demand. Highlight text in any application and press SUPER + SHIFT + Q. A popup marks each issue in the selection. You accept or skip each fix, then apply the corrected text through the clipboard. For longer text, SUPER + ALT + Q opens a Compose window that checks a draft in chunks.
Grammachy never checks while you type. Each check is an explicit trigger. No engine sends text off the machine.
Two engines, one honest trade
Harper is the default engine.
It runs in process through harper-core, compiles into the binary, and needs no download.
LanguageTool is opt in from Settings.
It needs a 250 MB download, a Java runtime, and about 1 GB of resident memory.
Harper catches about one in eight learner errors with zero false positives. LanguageTool catches about one in seven. That small gap is why LanguageTool stays opt in. There is no automatic fallback between engines. An engine that cannot answer says so, and you switch.
How it fits into Omarchy
The plugin is a Rust CLI plus a QML bar widget.
It is a verified plugin on the Omarchy plugin marketplace.
The omarchy plugin add command clones the repository and validates it, and nothing else.
The bar widget shows the pinned companion binary and its sha256 before you install it.
The setup command writes the two hotkeys into the Hyprland bindings file and reloads Hyprland.
The doctor command lists each system package and its state and installs nothing.
No step needs sudo.
