Turn Every Copy-Paste into Clean, Polished Writing with Clipboard Rewriter

If you write emails, reports, captions, or client updates all day, you already know how much time small edits can steal. Grammar fixes, tone adjustments, and quick rewrites add up fast.

That’s exactly why I built Clipboard Rewriter — a lightweight Python app that lives quietly in your Windows tray and rewrites copied text instantly using Google Gemini 1.5 Flash.

No tabs. No browser workflow. No switching context. Copy text, press a hotkey, and paste a cleaner version.

Why this tool is useful

Clipboard Rewriter helps when you need to:

Clean up grammar in seconds
Adjust tone (formal, casual, or business)
Rewrite rough drafts into polished text
Keep working without leaving your current app

It runs in the background, sends native Windows notifications, and keeps a history of rewrites automatically.
