Drop Grammarly when you already pay for ChatGPT, Claude, Gemini or Copilot

Proofread the text below as a careful copy editor.

Style: {{style_guide}}
Audience: {{audience}}
English variety: {{english_variety}}

Rules:
- Fix only spelling, grammar, punctuation, clear typos, and violations of the style guide.
- Do NOT change meaning, facts, numbers, names, links, quotes or formatting. Don't 'improve' wording that is already correct.
- If something might be an error but you're not sure (a name, a figure, a technical term), don't change it — list it under "Check".

Output exactly:
1. **Changes** — a numbered list: "original" → "corrected" (reason, max 8 words). Write "No changes needed" if none.
2. **Check** — anything ambiguous for me to decide.
3. **Corrected text** — in one block, ready to paste.

Rewrite the text below in the {{tone_preset}} tone from my style guide, for {{audience}}.

Style guide:
{{style_guide}}

Constraints: keep every fact, number, date, name and commitment exactly; keep it within {{max_words}} words; keep any links. Give two versions (A: closest to the original wording, B: more rewritten), then one line on what you changed in each.

Here are {{number_of_samples}} examples of writing from {{company_or_person}} that represent the voice we want:

{{writing_samples}}

Draft a one-page house style guide using ONLY patterns you can see in these samples. Sections: Language & spelling, Voice (5 bullet rules), Terms (always/never), Don'ts, three Tone presets (SUPPORT, SALES, INTERNAL) with one example sentence each. Where the samples are inconsistent, show both options and ask me to choose. Keep it under 350 words.

HOUSE STYLE GUIDE — paste into a Claude Project / ChatGPT Project / Gemini Gem / Copilot notebook as standing instructions.
Keep it under one page; the AI follows short, concrete rules better than long essays.

Language & spelling
- Variety: [US English | UK English]. Spell-check against it; flag the other variety's spellings.
- Oxford comma: [yes | no]. Numbers: words for one–nine, digits for 10+; always digits with units (5 GB, 3 days).
- Dates: [13 October 2026 | October 13, 2026]. Times: [9:00 | 9am]. Currency: $1,200 (no ".00" unless cents matter).

Voice
- Plain, direct, friendly. Short sentences (aim < 20 words). Active voice.
- We say "you" to the reader and "we" for the company. No "utilize", "leverage", "synergy", "best-in-class".
- Headlines and buttons: [Sentence case | Title Case].

Terms (always / never)
- [Product name] — always capitalised like this; never "[wrong variant]".
- [customer | client] — use "[chosen]" only.
- [sign up] (verb) vs [sign-up] (noun).

Don'ts
- No exclamation marks in customer emails. No emojis in [contracts, invoices, support replies].
- Never promise dates, refunds or legal outcomes in support replies.

Tone presets (ask for one by name)
- SUPPORT: warm, apologise once, give the next step and a timeframe.
- SALES: confident, specific benefit, one question at the end.
- INTERNAL: brief, bullet points, decision first.

Editing rules for the AI
- Preserve meaning, facts, names, numbers, links and formatting. Never add claims.
- When proofreading, change only what's wrong or violates this guide; list every change.

KEYBOARD-SHORTCUT WORKFLOW — get "select text → fixed text" down to a few keystrokes

1. One saved place for the instructions (all platforms)
   Create a Claude Project, ChatGPT Project, Gemini Gem or Copilot notebook called "Proofread" and paste the
   house style guide + the proofreading prompt as its instructions. Pin it. Each check is then just: paste text → Enter.

2. Snippet expansion for the prompt (no extra software)
   macOS: System Settings → Keyboard → Text Replacements → "+"
          Replace: ;pf    With: Proofread the text below using my house style. List every change as
          "original → corrected (reason)", then give the corrected text in one block. Change nothing else.
   Windows/other: use your existing text-expander, or keep the prompt as the Project instructions above.

3. Copy → ask → paste back (any app, any OS)
   Select text → Cmd/Ctrl+C → switch to the Proofread project (Cmd/Ctrl+Tab or the AI app's own global shortcut,
   if your app offers one — check its settings) → Cmd/Ctrl+V → Enter → copy the corrected block → switch back →
   Cmd/Ctrl+V.

4. Built-in, no AI subscription needed
   - Apple devices with Apple Intelligence: select text → Control-click → Writing Tools → Proofread / Rewrite
     (Friendly, Professional, Concise) — works in most apps and websites.
   - Microsoft Edge: built-in spelling/grammar in text boxes; Microsoft Editor extension for Chrome/Edge
     (basic checks free with a Microsoft account; advanced refinements with Microsoft 365).
   - Google Docs: Tab accepts a suggestion; Tools → Spelling and grammar for a full pass.
   - Word: Editor pane on the Home tab (Word for the web / Microsoft 365 on Windows).

5. Optional macOS Quick Action (copies text + prompt, opens your AI app)
   Shortcuts app → New Shortcut → Details: "Use as Quick Action", receive Text from Services/Quick Actions →
   actions: Text ("Proofread using my house style…\n\n[Shortcut Input]") → Copy to Clipboard → Open App (your
   AI app). Assign a key in the shortcut's details (Add Keyboard Shortcut). Then: select text → shortcut → Cmd+V → Enter.
