Prompt Enhancer: a focused Apple Writing Tools alternative for AI prompts
If you are looking for an Apple Writing Tools alternative that structures your AI prompts rather than polishing prose, this page gives you an honest comparison. The two tools solve different problems — and understanding which is which saves time.
Apple Writing Tools rewrites what you wrote. Prompt Enhancer structures what you are about to ask an AI.
Those are different problems. Read on to see where each tool fits — and why you might want both.
What Apple Writing Tools actually does
Apple Writing Tools (macOS Sequoia 15.1+, Apple Intelligence required) is a system-level rewriting assistant. Select text, right-click, choose Rewrite / Proofread / Summarize — and Apple’s on-device model polishes your prose.
It is free, private, fast, and deeply integrated into the OS. For everyday writing tasks — fixing a cover letter, tightening a Slack message, summarising a document — it is genuinely good.
At WWDC 2026 Apple is expected to ship a grammar checker and “Write With Siri” expansions. The toolset keeps getting wider.
What Apple Writing Tools does not do
Writing Tools is a prose editor. It does not know about prompt engineering, and it does not produce structured inputs for AI models.
When you paste “rewrite this” output into Claude or ChatGPT, the model still receives an unstructured blob of text. You get a generic answer, not a focused one.
Prompt Enhancer does one specific thing differently: it transforms your draft into an Anthropic-XML-structured prompt with explicit <role>, <context>, <task>, and <output_format> blocks — the structure Anthropic’s own documentation recommends for precise Claude outputs. That structure is invisible to Apple Writing Tools; it is not what Writing Tools was designed for.
Where Apple Writing Tools has gaps today
As of macOS Sequoia 15.1, Writing Tools does not activate in all third-party apps. Electron-based apps (VS Code, Slack desktop, Notion desktop, Discord) had no Writing Tools support until Electron v36 added partial context-menu integration in May 2025 — and even then, activation depends on how each app implements text areas. Chrome-rendered apps vary further.
Prompt Enhancer uses a global hotkey (⌃⌥⌘P) that works through macOS Accessibility APIs. It triggers from any text field in any app — Claude.ai in Safari, ChatGPT in Chrome, VS Code, Cursor, Notion, Figma, Linear, Mail, Telegram — without requiring the app to opt in to anything.
How they can coexist
A realistic workflow for a developer:
- Draft a rough task description in whatever app you are in.
- Hit ⌃⌥⌘P — Prompt Enhancer rewrites it in-place into a structured Claude prompt in ~4 seconds.
- Submit to Claude. Get a focused, detailed answer.
- Optionally use Apple Writing Tools on Claude’s output to polish tone before pasting it into a doc or email.
Each tool does its own job. Neither replaces the other.
Pricing context
Apple Writing Tools: free, requires Apple Intelligence (macOS Sequoia 15.1, supported hardware, U.S. English device language set).
Prompt Enhancer: $29 one-time (lifetime). Start with 3 free enhancements (no signup), then a 7-day free trial. With Pro you can use BYOK — your own Anthropic key, stored in macOS Keychain, direct to api.anthropic.com, no server in between.
Bottom line
If you want cleaner prose, Apple Writing Tools is already on your Mac and costs nothing.
If you want structured, high-signal prompts that get better answers out of Claude — Writing Tools will not help with that. Prompt Enhancer will.
How they compare: Prompt Enhancer as an Apple Writing Tools alternative
| Feature | Prompt Enhancer | Alternative |
|---|---|---|
| Primary job | Structures drafts into Anthropic-XML prompts for AI models | Rewrites and polishes existing prose |
| Output format | Improved natural-language prose (same structure) | |
| Works in Electron apps (VS Code, Slack, Notion desktop) | Yes — global hotkey via Accessibility APIs, any text field | Partial — requires Electron v36+; app must implement context-menu support |
| Works in Chrome / browser apps | Yes — any focused text field in any browser | Varies by app; not guaranteed in all Chrome-rendered UIs |
| Requires Apple Intelligence | No — works on any macOS with Accessibility permissions | Yes — macOS Sequoia 15.1+, supported hardware, U.S. English locale |
| Price | $29 one-time; Pro BYOK option | Free (bundled with Apple Intelligence) |
| Privacy model | BYOK: API call goes directly to api.anthropic.com, no proxy, no logs; Pro: managed key | On-device processing (Apple Intelligence on-device model) |
| Prompt engineering knowledge | Applies Anthropic official XML prompt standard | None — generic rewrite, not prompt-aware |
| App signed / notarized | Yes — fully notarized and stapled, opens normally on double-click | System-native, fully trusted |
| Platforms | macOS (arm64) + Windows (.msi); Linux Q3 2026 waitlist | macOS Sequoia 15.1+ and iOS/iPadOS 18.1+ only |
Honest caveats
- The Prompt Enhancer macOS DMG is Apple-notarized since June 2026 — installs without Gatekeeper warnings. Apple Writing Tools is a built-in system component that requires no separate install at all.
- Prompt Enhancer launched public beta on 2026-05-23 (v0.1.1). It has no track record yet. Apple Writing Tools has shipped in macOS Sequoia since late 2024 and has a larger installed base.
- Apple Writing Tools is free with supported Apple hardware. Prompt Enhancer has a cost ($29 one-time, or BYOK free). If your only goal is prose editing, Apple Writing Tools wins on price.
- Apple Writing Tools processes text on-device by default, which is a strong privacy story. Prompt Enhancer BYOK sends your text to api.anthropic.com — same as using Claude.ai manually, but worth noting.
- Electron app support for Apple Writing Tools improved significantly with Electron v36 (May 2025). The coverage gap between the two tools in Electron apps is narrowing over time.
- WWDC 2026 (June 8) may expand Apple Writing Tools further. This comparison reflects the state as of May 2026 and will be updated after the keynote.
- Linux is not supported by Prompt Enhancer (Q3 2026 waitlist). Apple Writing Tools is macOS/iOS only. Neither covers Linux today.
