How to Rewrite Copied Text from British to American English on Mac
How to Rewrite Copied Text from British English to American English on Mac
If you're a Mac user who regularly switches between British and American English—whether you're editing content for different markets, collaborating with international teams, or localizing your writing—you know how tedious manual rewrites can be. Spelling differences (colour vs. color), vocabulary swaps (lift vs. elevator), and phrasing conventions add up quickly.
The good news: you don't need separate tools or cloud-based services anymore. With ClipHistory, a macOS clipboard manager, you can rewrite any copied text from British to American English instantly, right on your Mac, using AI transformations.
Why Clipboard Management Matters for Text Rewrites
Every time you copy text to rewrite it, you're creating friction in your workflow. You copy, paste into a converter, wait for results, then manually integrate the changes back into your document. This interrupts your flow and wastes time.
ClipHistory eliminates that friction by making AI rewrites a one-keyboard-shortcut operation.
Press ⌘⇧V to open your clipboard history, select the text you want to rewrite, trigger the AI transform, and you're done. The rewritten version is ready to paste immediately. No switching apps, no accounts, no delays.
How ClipHistory's AI Rewrite Feature Works
ClipHistory stores your full clipboard history—up to 150 unpinned clips plus unlimited pinned ones—and auto-detects what you've copied (URLs, code, emails, plain text, etc.). This context-awareness matters when rewriting, because the AI can apply the right tone and style for British-to-American conversion.
The rewrite transformation uses AI from five different providers:
- Anthropic (Claude)
- OpenAI (GPT-4 / GPT-4o)
- DeepSeek
- Google (Gemini)
- Custom endpoints
The crucial part: you bring your own API key. This means:
- No new account to create
- No ClipHistory subscription or cloud dependency
- Your text never leaves your Mac unless it goes to your chosen AI provider
- 100% local clipboard history storage
If you already have an OpenAI or Anthropic account, you likely have unused API credits. Use those for rewrites at minimal cost.
Step-by-Step: Rewrite British Text to American English
- Copy your British English text to your clipboard as normal.
- Press ⌘⇧V to open ClipHistory.
- Select the clip you want to transform.
- Click "Rewrite" (or your configured AI transform button).
- Choose your AI provider and adjust the prompt if needed:
- "Rewrite this text from British English to American English spelling, vocabulary, and phrasing conventions."
- Confirm the transformation.
- Copy the result and paste it into your document.
The entire process takes seconds. For bulk rewrites (a whole article, for example), you can pin multiple clips and batch-process them.
Why ClipHistory Beats Online Converters
Many writers default to online British-to-American converters. Here's why ClipHistory is better:
Speed: No browser switching. One shortcut opens your clipboard history with AI rewrites built in.
Privacy: Your text stays on your Mac. Converters upload your content to their servers; ClipHistory processes it locally, then sends it only to your AI provider of choice.
Context: AI rewrites understand nuance. Simple word-swapping (changing colour to color) is mechanical; AI can rewrite entire sentences to match American conventions while preserving your voice.
Flexibility: You control which AI provider handles the rewrite. Using Claude? Rewrite with Claude. Prefer GPT-4? Switch to OpenAI. No tool lock-in.
Cost: At $19.99 lifetime—one payment, no recurring subscription—ClipHistory costs less than a month of premium converter subscriptions.
Real-World Example
Imagine you've copied a paragraph from a British client's brief:
"The lift was out of order, so the colour-coding system for organising our toolkit became essential."
Open ClipHistory (⌘⇧V), select the clip, hit rewrite, and seconds later you get:
"The elevator was out of order, so the color-coding system for organizing our toolkit became essential."
The AI catches not just lift→elevator and colour→color, but also organising→organizing. Manual rewrites would take longer and risk missing variants.
Beyond British-to-American: Other ClipHistory Transforms

- Rephrase for tone (formal, casual, technical)
- Auto-detect text type and suggest transforms
All from the same ⌘⇧V shortcut. All 100% local. All with your own API keys.
