What should I look for in an AI rewriting app for Mac?

Local processing with no account, the option to use your own API key (so you control model and cost), a global shortcut for instant access, and integration with your existing copy-paste flow.

Is ClipHistory a subscription?

No. It's a one-time $19.99 purchase with a 12-month license and no auto-renewal. AI usage is billed separately by your chosen provider.

Will it run on my Mac?

If you're on macOS 12 or later, yes. ClipHistory is a universal binary that runs natively on both Apple Silicon and Intel, and it's signed and notarized by Apple.

What else does it do besides rewrite?

It's a full clipboard manager: 150 unpinned plus unlimited pinned clips, snippets, boards, a paste stack, and other AI transforms (summarize, translate, clean).

Rewrite Text with AI on Mac: What to Look For

Q: Does ClipHistory include its own AI model?

No. You bring your own API key from one of five providers (Anthropic, OpenAI, DeepSeek, Google, or a custom endpoint), and each rewrite call goes directly to that provider from your Mac.

There are plenty of Mac apps that promise to rewrite your text with AI. The useful question isn't which one wins a popularity contest — it's which qualities actually matter day to day. This guide lays out what to evaluate, then shows how a clipboard-based approach handles rewriting.

The qualities that matter

When you compare AI rewriting tools for macOS, weigh these:

1. Where the work happens

Some tools route your text through their own servers and store it in an account. Others keep processing local and only call out to an AI model directly. If the text you rewrite is sometimes confidential, local-first with no account is the safer default.

2. Whose model (and bill) it uses

A tool that bundles its own AI usually bundles a subscription. A tool that uses your own API key lets you choose the provider, the model, and the cost — and there's no recurring fee for the app itself beyond what you paid for it.

3. How fast it is to invoke

Rewriting is only useful if it's instant. A global keyboard shortcut that works in any app beats opening a separate window every time.

4. Whether it fits your existing copy-paste flow

You already copy text constantly. A tool that rewrites at the clipboard level slots into that habit instead of adding a new one.

How ClipHistory approaches rewriting

ClipHistory is a clipboard manager for macOS that keeps your last 150 clips and adds AI transforms on top, including Rewrite. It's built around the four qualities above.

The flow:

Copy the text (Cmd+C).
Press the global shortcut Cmd+Shift+V.
Select the clip and run Rewrite.
Give a direction — clearer, shorter, more formal, paraphrased — and paste.

Your original stays in history, so you can compare or iterate.

The transforms you get

Rewriting is one of several AI transforms:

Rewrite — rephrase, restructure, change tone, paraphrase.
Summarize — condense long text to key points.
Translate — move text between languages.
Clean — fix typos, spacing, and punctuation without changing meaning.

Keeping them separate means each does one job predictably.

Local processing, your own key

ClipHistory has no account and no cloud sync. It connects to your own API key from one of five providers — Anthropic, OpenAI, DeepSeek, Google, or a custom endpoint — and each rewrite call goes directly to that provider.

The practical upshot:

Your clipboard history lives only on your Mac.
Only the clip you rewrite is sent, and only to your provider.
You choose the model per task and pay the provider directly.

Trust and compatibility

A rewriting tool sits in your daily flow, so it should be trustworthy and broadly compatible:

Signed and notarized by Apple, so Gatekeeper trusts it.
Universal binary, running natively on Apple Silicon and Intel.
macOS 12 or later.

Beyond rewriting: the clipboard you keep

Because it's a clipboard manager first, ClipHistory also gives you:

150 unpinned clips plus unlimited pinned ones.
Snippets for text you reuse constantly.
Boards to group related clips.
A paste stack for pasting several items in sequence.

So the same app that rewrites your text also stops you from losing the thing you copied five minutes ago.

Pricing

ClipHistory is a one-time $19.99 purchase with a 12-month license and no auto-renewal. You're not signing up for a subscription, and AI usage is billed separately by whichever provider's key you use.

Questions worth asking before you buy

Before committing to any AI rewriting app for Mac, a short checklist saves regret:

Does it require an account or cloud sync? If yes, your text lives somewhere you don't fully control.
Can I use my own model? Bundled models mean you can't tune cost or quality, and usually mean a subscription.
Is it signed and notarized? Unsigned apps fight Gatekeeper and are harder to trust.
Does it run natively on my chip? A universal binary runs well on both Apple Silicon and Intel.
Will it survive my workflow? A global shortcut and clipboard integration beat a standalone window you have to remember to open.

ClipHistory is built to answer all five the way a careful user would want: no account, your own key, signed and notarized, universal binary, and a global Cmd+Shift+V shortcut tied to the clipboard you already use.

A worked example

Original:

We regret to inform you that the item you ordered is currently unavailable and we are unable to provide a delivery date at this time.

Rewrite with "shorter and warmer":

Sorry — that item is out of stock right now, and we don't have a delivery date yet. We'll let you know the moment that changes.

Same news, better delivered, one shortcut.

Setup checklist
