OFFLINE GRAMMAR CHECKER

A private, offline grammar checker that runs on your Mac.

Pick an open model, download it once, and it runs right on your Mac. No internet, no API key, no bill. MacWriteBuddy fixes your writing in any app, and with a local model your words never leave the room.

Version 1.2.2macOS 14 Sonoma or laterApple silicon & IntelHow to install
MacWriteBuddy’s Models settings: Apple Intelligence built into macOS, and open models with their download size and memory needs, with Qwen3 4B Instruct in use and Llama 3.2, Gemma 3, Phi-4 mini, and Mistral 7B ready to get.

Highlights

Small models, picked for writing

Settings › Models lists a few small open models chosen for fixing and rewriting text, such as Qwen3 4B, Llama 3.2, Gemma 3, Phi-4 mini, and Mistral 7B, with the download size and memory each one needs. Download one, and every shortcut uses it.

Apple Intelligence, with nothing to download

On macOS 26 or later, MacWriteBuddy can use Apple Intelligence, built into macOS, so you can start fixing your writing without downloading a model at all.

Or bring your own server

Already run Ollama or LM Studio? Point MacWriteBuddy at it and your text stays on your own network, on your own hardware.

Private by design

MacWriteBuddy has no server that receives your writing. It only goes online to download the models you pick, check for updates, and check a Pro license key. There’s no login, no account, and no tracking.

MacWriteBuddy’s Privacy settings: your selection goes from Mail to Qwen3 4B on this Mac and back as fixed text, with 0 bytes sent to MacWriteBuddy. No account, no analytics or tracking, text read only when you press a shortcut, password fields always skipped, and recent fixes kept on this Mac for 7 days.

Which Mac do you need?

macOS 14 Sonoma or later, on Apple silicon or Intel. Local models run best on Apple silicon with 8 GB of memory or more; on older Macs, a cloud provider or your own Ollama server keeps things quick.

QUESTIONS

Good to know.

More answers on the MacWriteBuddy home page.

Does MacWriteBuddy work without an internet connection?

Yes, with a local model. Download a model once in Settings › Models and MacWriteBuddy fixes your writing with Wi-Fi switched off. It only goes online to download the models you pick, to check for updates, and, with Pro, to check your license key.

Does my text get uploaded to your servers?

Never. MacWriteBuddy has no server that receives your writing. With a local model, your text never leaves your Mac at all. With a cloud provider, it goes straight from your Mac to that provider using your key. The app only goes online to download the models you pick, to check for updates, and, with Pro, to check your license key.

Which models can I use?

Download a small open model from the built-in list and it runs right on your Mac, or connect your own Ollama or LM Studio server. You can also use any model your cloud provider offers. Each action can use a different model.

Which Mac do I need?

macOS 14 Sonoma or later, on Apple silicon or Intel. Local models run best on Apple silicon with 8 GB of memory or more; on older Macs, a cloud provider or your own Ollama server keeps things quick.
