Does macOS have a built-in rephrase tool?

There is no system-wide rephrase command. ClipHistory adds a Rewrite transform that you run on any copied text from your clipboard history.

Will rephrasing overwrite my original text?

No. The rewritten text comes back as a new clip. Your original copy stays in your clipboard history so you can compare or revert.

What does it cost to rephrase?

The app is $19.99 once for a 12-month license. AI rephrasing uses your own provider API key, so you pay your provider directly for usage.

Can I rephrase without sending text to the cloud?

The rephrase step sends only that text to your chosen AI provider. If you point ClipHistory at a custom self-hosted endpoint, you control where it goes entirely.

How to Rephrase Text on a MacBook

Rephrasing is one of those small tasks that interrupts your flow. You have a sentence that says the right thing in the wrong way, and fixing it by hand takes longer than it should. On a MacBook, you can hand that job to AI without leaving the app you are working in.

The fastest method: rewrite from the clipboard

macOS does not include a built-in rephrase command, so the trick is to put the rewrite step where your text already is, the clipboard.

With ClipHistory, the steps are:

Select the sentence and copy it (Cmd+C).
Press Cmd+Shift+V to open your clipboard history.
Pick the clip and choose the Rewrite transform.
Paste the result (Cmd+V) where you want it.

The rephrased version comes back as a new clip, so your original wording is still in history if you change your mind.

How the rewrite works

ClipHistory sends only the selected text to the AI provider you connected, then returns the rephrased version. You bring your own API key from Anthropic, OpenAI, DeepSeek, Google, or a custom endpoint. There is no ClipHistory cloud in the middle and no account to create.

Because you control the key, you control the cost and the destination of the text. Short rewrites are cheap on most providers.

Rewrite vs. clean vs. summarize

These three transforms solve different problems:

Rewrite keeps the meaning but changes the phrasing.
Clean removes formatting junk like stray line breaks without changing words.
Summarize shortens the text by cutting content.

If your sentence is fine but awkward, you want Rewrite. If it is full of line breaks pasted from a PDF, you want Clean first.

Rephrasing for tone

Rewrite is useful when the meaning is right but the register is off. A blunt note can become more diplomatic, a stiff line can become more natural. If you specifically need a formal tone, that is a focused job worth its own pass.

Save phrasings you reuse

If you find yourself rephrasing the same kinds of text repeatedly, for example turning rough notes into polished status updates, save the polished versions as snippets. A snippet is reusable text you can paste with a keystroke, which saves you from re-running the same transform.

What it needs to run

ClipHistory is signed and notarized by Apple and ships as a universal binary for Apple Silicon and Intel Macs. It requires macOS 12 or later. The license is a one-time $19.99 payment covering 12 months, with no auto-renewal.

Everything except the AI transform stays on your Mac: the clipboard history is stored locally, never synced to a server.

Why not just use a website?

You can paste into a web tool, but every rephrase becomes a tab switch, a paste, a wait, and a copy back. Doing it from the clipboard keeps the whole loop on the keyboard and inside whatever app you are already using. For something you do many times a day, that saved friction adds up fast.

You can also chain transforms. Rephrase a paragraph, then run Translate on the result if you need it in another language, or Summarize it if it is still too long. Each step produces a fresh clip, so you never lose an earlier version while you experiment with wording.

Bring your own AI provider

ClipHistory does not bundle a hidden AI service. You connect a key from one of five providers, Anthropic, OpenAI, DeepSeek, Google, or a custom endpoint you control, and rewrites run through that. There is no markup and no middleman: you pay your provider for what you use, and the text goes only where you sent it.

This is also why there is no account to create. The app runs against your key, stores your clipboard history locally, and sends only the specific clip you act on, and only at the moment you trigger a transform. For drafts you would rather not leave on a third-party server, a custom self-hosted endpoint keeps everything in your hands.

A worked example

Suppose you jotted a quick line: "hey can you get me those numbers asap, kind of urgent." Copy it, open clipboard history, and run Rewrite. You get back something like a clear, polite request that keeps the urgency without the abruptness. If you want it more formal, run Rewrite again on the result. If you want it in Spanish for a colleague, run Translate. Three transforms, three new clips, and your original casual note is still there in case you want it.

Because the history keeps 150 unpinned clips plus unlimited pinned ones, none of these intermediate versions crowd out your real work. Pin the ones you want to keep; let the rest age out naturally.
