What it does
PureEdit opens your document, reads it through a fast native checker, and shows every grammar, spelling, punctuation, and style suggestion side by side with your original — so you stay in control of every change. The entire engine runs on your machine, which means a private letter, a legal draft, or an unpublished manuscript stays exactly where you put it.
Features
100% On-Device
The checker runs in-process on your Mac. Your writing never touches the network — no cloud, no account, no tracking.
Grammar & Style
A fast native engine catches grammar, spelling, punctuation, and style issues across thousands of rules.
Optional On-Device AI
Add a local AI model for deeper rewrites and tone suggestions. It runs on Apple Silicon — still fully offline.
Opens Everything
Word, Pages, LibreOffice, rich text, plain text, and Markdown — open, check, and save back in the original format.
Side-by-Side Review
See your original and the corrected version together. Accept changes one at a time, or all at once.
Quick Formatting
A built-in toolbar for font, size, colour, bold, italic, underline, strike, and paragraph styles for light edits.
Scriptable CLI
The bundled pecheck command checks and exports documents from the terminal or a build pipeline.
Privacy First
No sign-in, no analytics, no telemetry. Everything happens on your machine, the way it should.

Moss, our rock-golem mascot, isn't much of a typist — which is exactly why he built PureEdit. He does the proofreading so you don't have to.
