The same Rephraser you know on Mac, rebuilt natively for Windows 10 / 11. On-device AI via llama.cpp. No cloud. No API keys. Free and open source.
Windows 10 version 1809 or later · Windows 11 · x64 · ~15 MB installer, ~0.8 GB for default AI model
Double-click Rephraser-setup.exe from your Downloads folder. It's a per-user installer (no admin required).
Windows will say "Windows protected your PC" with "Unknown publisher" under the file name. That's because Rephraser isn't code-signed yet (a cert costs $70–$300/yr and we haven't pulled the trigger on that for a free tool at v0.1).
Click More info, then Run anyway. This tells Windows you trust the publisher; the file is immediately whitelisted on your machine.
Want proof the installer is clean? Every Windows release is scanned by VirusTotal in CI — the scan URL is attached to the GitHub release notes for the binary you downloaded.
On first launch, Rephraser opens a small tray window. Pick Qwen 2.5 0.5B for the smallest download (~0.4 GB) or Gemma 3 1B for the default (~0.8 GB). The download resumes if your connection drops.
Select text in any app — Word, Outlook, Slack, Chrome, VS Code —
press Ctrl + Alt + R, and Rephraser's floating panel
appears over whatever you're working on. Enter to paste, Escape
to cancel. Your clipboard is preserved.
SmartScreen, antivirus flags, hotkey conflicts, ARM64, enterprise silent install, privacy, and offline behaviour are all answered in the main FAQ on the Rephraser home page — one place for both Mac and Windows so you don't have to hunt across pages.
