What is the keyboard shortcut to fix grammar?

Press Cmd+Shift+V to open your clip history, then run the Rewrite transform on the copied text. ClipHistory uses Cmd+Shift+V as its global shortcut.

Does this work outside of Apple's apps?

Yes. Because it works from your clipboard, you can correct text copied from any app - chat tools, code editors, web forms, terminals - not just fields that support macOS's built-in check.

Will it change my wording too much?

Rewrite aims to fix mechanics while keeping your meaning, but always review the result. Your original text remains in your clip history so you can revert if a correction overreaches.

A Fix-Grammar Shortcut for Mac From Your Clipboard

Q: Which AI corrects the grammar?

The provider you connect with your own API key: Anthropic, OpenAI, DeepSeek, Google, or a custom endpoint. Only the selected clip is sent to that provider.

macOS has built-in spelling and grammar checks, but they only fire inside certain text fields and they miss a lot. A clipboard-based fix-grammar shortcut works everywhere: any app, any field, as long as you can copy the text.

Here is how to set one up using an AI clipboard manager.

The core idea

Grammar fixing is a kind of rewrite - keep the meaning, correct the mechanics. With a clipboard manager that has AI transforms, you copy the text, run a Rewrite transform aimed at correcting grammar, and paste the clean version back.

The shortcut that ties it together is Cmd+Shift+V, which opens your clip history from anywhere.

The workflow

Select the text with the mistakes and copy it (Cmd+C).
Press Cmd+Shift+V to open your clip history.
Select the clip and run Rewrite to correct grammar, spelling, and phrasing.
Paste the corrected text back over the original.

Your original stays in the history, so if a correction goes too far, you can recover the source.

Why a clipboard shortcut beats built-in checks

	macOS built-in check	Clipboard fix-grammar
Works in any app	No, only certain fields	Yes
Fixes phrasing, not just spelling	Limited	Yes
One shortcut everywhere	No	Cmd+Shift+V

The built-in checker is fine for obvious typos in supported fields. A clipboard shortcut covers code comments, terminal text, web forms, chat apps - anywhere you copy from.

You choose the AI behind it

ClipHistory does not run its own grammar engine. You connect your own API key from one of five providers - Anthropic, OpenAI, DeepSeek, Google, or a custom endpoint - and only the clip you selected is sent to that provider for the correction.

So:

You pick the model that checks your grammar.
You pay your provider directly.
There is no ClipHistory account and no cloud copy of your text.

No key, no AI transforms - but the clipboard manager still works.

Setup, step by step

Install ClipHistory - universal binary, macOS 12+, signed and notarized by Apple.
Open settings and add an API key for a provider you use.
Copy any text and press Cmd+Shift+V to confirm your history opens.
Run Rewrite on a clip to see the corrected output.

After this, fixing grammar is: copy, Cmd+Shift+V, Rewrite, paste.

Clean vs. rewrite for grammar

If your text is mostly fine but cluttered with stray line breaks or formatting from a copy-paste, the Clean transform handles that. For actual grammar, spelling, and phrasing corrections, use Rewrite. Many people run both: Clean to tidy, Rewrite to correct.

Reuse common fixes with snippets

For text you send often - a standard reply, a bio, a disclaimer - fix it once and save it as a snippet. Then you paste the already-correct version instead of re-checking it every time. Use the fix-grammar shortcut for fresh text and snippets for repeatable text.

Privacy

Running a grammar fix sends that one clip to your configured AI provider. Use normal judgment and avoid sending sensitive secrets you would not paste into that provider's own interface. Everything else stays local: your clip history, snippets, and boards live on your Mac with no cloud and no account.

A repeatable grammar workflow

Once it is set up, the same five steps cover almost any grammar fix:

Write your message or document as usual, without stopping to self-edit.
Select a paragraph and copy it.
Press Cmd+Shift+V, choose the clip, and run Rewrite asking it to fix grammar and punctuation only.
Compare the corrected clip to the original, which is still in your history.
Paste the version you want.

Keeping grammar and tone as separate prompts gives cleaner results than asking one request to do everything. If you want the text shortened too, run a second rewrite pass focused on concision after the grammar pass.

Why a one-time license fits a daily task

Grammar checking is something you do many times a day, every day. ClipHistory is a one-time purchase - $19.99 for a 12-month license, with no auto-renewal - so a constant-use tool does not turn into a recurring charge you forget about. You supply your own API key, so the AI cost is billed directly by your provider at their rates, with nothing added on top.

Honest expectations

An AI grammar fix is a strong, fast pass, not an infallible editor. It catches the typos and awkward phrasing you would fix yourself given time, and it works in places the built-in checker cannot reach. Read the result before you send anything important - the original is always one click away in your history if you need it.
