PureEdit

iPhone · iPad · Mac · On-Device · No Cloud AI

Your writing stays on your device.

A local grammar checker for people who want better feedback than the tools built into Word, Pages, or LibreOffice — without pasting drafts into ChatGPT, Grammarly, or another cloud AI. Now on the App Store.

Download on the App Store Support

Free on the App Store for iPhone, iPad, and Mac (Apple Silicon). PureEdit Pro is a one-time in-app unlock.

The promise: Grammar checking runs on your iPhone, iPad, or Mac. Your document is not uploaded to PureEdit or a cloud AI for that check.

Who it’s for

A good fit if you…

  • Won’t paste essays or drafts into AI chat sites
  • Want stronger grammar help than built-in checkers
  • Work in Word, Pages, LibreOffice, or Markdown files
  • Prefer accept/reject review over “rewrite my paper”

Not the right tool if you…

  • Want an AI ghostwriter or full essay generator
  • Need Grammarly-style checks in every browser box
  • Live only in Google Docs (no official add-on yet)
  • Need a human copyeditor’s final pass

What it does

Open a document, run a check, and review suggestions side by side with your text. Accept or reject each change yourself. Export a corrected file when you’re done. The default path is a fast on-device grammar engine — not a remote model.

Features

On-device grammar

Spelling, grammar, punctuation, and style rules run in-process on your device. No PureEdit cloud for your draft.

Real documents

Word, Pages, LibreOffice, rich text, plain text, and Markdown — open, check, and export.

You stay in control

Review every suggestion. Accept one at a time, ignore words you choose, or apply fixable items in batch.

Optional AI style

A separate, opt-in on-device style pass (Apple Intelligence / local model). Not required for normal checking — and not a cloud chatbot.

No account to check

Open a file and check. Purchases use the App Store when you unlock full documents; checking itself doesn’t need a PureEdit login.

CLI for power users

The direct Mac build can include the pe helper for scriptable checks from the terminal.

Meet Moss

Moss, our rock-golem mascot, isn’t much of a typist — which is exactly why he cares about proofreading tools that don’t ship your manuscript to the cloud.

Pricing
