Undo Ai Make Ai Work Seem

Undo-Ai rewrites stiff, robotic text into writing that flows naturally — the way a real person would actually say it. Paste a paragraph, choose your voice, and get back a version with genuine rhythm, contractions, and the relaxed cadence that makes writing feel human.

WHAT IT DOES
━━━━━━━━━━━━
- Rewrites pasted text in Casual, Professional, Academic, or Creative tone
- Optional light imperfections (realistic contractions, natural phrasing) so output doesn't feel template-clean
- Works on blog drafts, emails, social posts, product copy, cover letters, scripts — anything you wrote or are refining
- On-device processing via Chrome's built-in Gemini Nano AI — your text never leaves your machine
- Rule-based fallback engine runs instantly even when Gemini Nano is unavailable or not yet downloaded
- Works fully offline once the model is downloaded

PRIVACY FIRST
━━━━━━━━━━━━
All text processing happens on your device. No servers receive your input. No analytics. No tracking. The only external connection is to ExtensionPay (extensionpay.com) to check your subscription status — and even that never sees the text you rewrite.

RESPONSIBLE USE
