## In short

ToneMate is a native macOS app that runs AI actions on text you select, from a global keyboard shortcut: proofread, rewrite, translate, summarize, reply and dictate. You choose the model: one on your Mac through Ollama or MLX, or your own API key from a cloud provider. It is designed as a one-time purchase that includes 2 licenses, with no subscription.

## Quick facts

- Works on text you select, with a shortcut you assign, rather than inside a single editor.
- Proofread fixes grammar, spelling, punctuation and style and shows every change.
- An optional inline assistant underlines mistakes as you type, only in the apps you allow.
- You choose the model, local or cloud, and the purchase is planned as one-time, with no subscription.

## How it works

1. **Select the text.** Highlight what you want to check, in the app where you are writing.
2. **Press your shortcut.** Run Proofread, or any other action, from a shortcut you assigned.
3. **Review the changes.** See what was fixed, word by word, and accept or copy the result.
4. **Optionally, turn on inline suggestions.** Add the apps where you want underlines while you type.

## How the approach differs

Many writing tools work inside their own editor or through a browser extension. ToneMate takes a different route: it is a Mac app that acts on the text you select, in the app you are already using, when you ask it to. The optional inline assistant is the exception, and it only runs in apps you add yourself.

That choice has trade-offs. It means ToneMate is not always watching, which some people prefer and others will miss. And because it is a macOS app, it is not a browser extension and does not run on Windows or on a phone.

## Who it may suit, and who it may not

- It may suit you if you write in several Mac apps, want to choose where your text is processed, and prefer paying once.
- It may suit you if you also want to translate, rewrite, reply or dictate from the same place.
- It may not suit you if you need a browser extension, Windows or mobile support, or you do not want to set up a model.
- It is in free beta: you can download it and try it, but it is not on sale yet, and the app is in English for now.

## Two approaches to writing help

|  | A tool built into an editor or extension | ToneMate |
| --- | --- | --- |
| Where it acts | Inside the editor or the pages where the tool is installed | On the text you select in the app you are using |
| When it acts | Often as you type | When you press a shortcut; optional inline suggestions in apps you allow |
| Where text is processed | Decided by the service | Your choice: a local model on your Mac or your own API key |
| How it is paid | Varies by product | Planned as a one-time purchase that includes 2 licenses |

## Frequently asked questions

### Is ToneMate a Grammarly replacement?

It depends on what you use a writing tool for. ToneMate proofreads text you select, offers optional inline suggestions in the apps you allow, and also translates, rewrites, summarizes, replies and dictates. It is not a browser extension and is not available for Windows or mobile. We have not compared it feature by feature with other products.

### Does ToneMate work in my browser?

It works in apps where you can select, copy and paste text, which includes text fields in a browser, because it acts at the macOS level. It is not a browser extension, and we are still verifying specific apps one by one.

### How is it paid for?

ToneMate is planned as a one-time purchase that includes 2 licenses, with no subscription. If you use a cloud model, the provider bills your own API usage. The final price appears in the pricing section once sales open.

### Is my text sent to a server?

ToneMate never sends your text to its own servers. With a local model your text is processed on your Mac; with a cloud model it goes straight to the provider whose API key you added. The app only contacts ToneMate to check your license.

### Can I buy or download ToneMate today?

You can download it, but not buy it yet. ToneMate is in free beta: download the app and request a free license key, which has no fixed end date. The plan for the full version is a one-time purchase that includes 2 licenses; when the first stable version comes out, a 30-day free trial starts.
