How to Install Prompt Enhancer

Prompt Enhancer is available for Mac and Windows. The macOS DMG is Apple-notarized (June 2026) and installs without Gatekeeper warnings. The Windows build is currently unsigned, so SmartScreen shows a one-time "unknown publisher" prompt — click More info → Run anyway to proceed (you can verify the download with the SHA-256 hash below). Nothing is sideloaded, and your API key goes directly to Anthropic.

1. Install on macOS

Download for Mac (.dmg)
  1. Open the downloaded PromptEnhancer-mac.dmg and drag the app to Applications.
  2. Open Prompt Enhancer from Applications. The DMG is Apple-notarized, so it launches normally on a double-click — no Gatekeeper prompt.

Requires macOS 13 (Ventura) or later. Universal build — works on Apple Silicon (M1/M2/M3/M4) and Intel Macs.

2. Install on Windows

Download for Windows (.msi)
  1. Click Download — you will get a file named PromptEnhancer-win.msi. Keep the .msi extension — do NOT rename it to .exe. Renaming it to .exe is exactly what triggers the "This app can't run on your PC" error, because an .msi is a Windows Installer package, not a standalone program.
  2. Double-click PromptEnhancer-win.msi to start the installer.
  3. If Windows shows "Windows protected your PC" (SmartScreen), click More info, then click Run anyway. This warning is expected because the Windows build is an unsigned indie release — the installer is safe and nothing extra is bundled. Want proof? Verify the SHA-256 hash below.
  4. Follow the installer steps, then launch Prompt Enhancer from the Start menu. Press Ctrl + Alt + P in any text field to enhance your prompt.

Requires Windows 10 or 11 (x64). Microsoft Edge WebView2 runtime is required and ships with Windows 10/11 by default — the installer will pull it automatically if it is missing.

Why does Windows warn about an unknown publisher?
The "unknown publisher" badge and any antivirus false-positive are because the Windows build is currently unsigned — it has no code-signing certificate yet, so Microsoft SmartScreen and some AV engines flag it on sight. This is a well-known situation for new Tauri/Rust apps. Your API key is sent directly to api.anthropic.com; nothing passes through our servers. Every purchase is covered by a 30-day, no-questions money-back guarantee.

Frequently Asked Questions

Is Prompt Enhancer safe to install on Mac?

Yes. Prompt Enhancer is a native macOS binary — Apple-notarized since June 2026. Nothing is sideloaded. Your API key traffic goes directly to api.anthropic.com.

Will macOS say "unidentified developer"?

No. Prompt Enhancer is Apple-notarized and stapled, so the current DMG passes Gatekeeper cleanly and opens normally on a double-click. There is no "unidentified developer" prompt to work around.

Does it work on Apple Silicon Macs?

Yes. Prompt Enhancer ships as a universal build that runs natively on Apple Silicon (M1, M2, M3, M4) and Intel Macs. macOS 13 (Ventura) or later is required.

Windows says "This app can't run on your PC" — what's wrong?

You most likely renamed the file from PromptEnhancer-win.msi to something ending in .exe, or your browser saved it with the wrong extension. An .msi is a Windows Installer package — Windows cannot execute it if the extension is changed. Re-download PromptEnhancer-win.msi and run it exactly as downloaded, without renaming it.

Windows says "Windows protected your PC" — is this safe?

Yes, it is safe. The Windows build is currently unsigned, so SmartScreen shows a one-time warning. Click More info, then Run anyway to proceed — and you can verify the download against the published SHA-256 hash above. Your API key is sent directly to api.anthropic.com — nothing passes through our servers.

My antivirus flagged Prompt Enhancer. Is it malware?

No. Brand-new Tauri/Rust executables are routinely false-flagged by antivirus engines because they are statically compiled and unfamiliar to signature databases — this is a well-documented false positive in the Tauri community. Email support@promptenhancer.online and we will help you add an exception or submit a whitelist request to your AV vendor.
