AI Humanizer for Mac.
Humanizer is a native Mac app built for desktop drafting. Select text in any app, right-click → Services → Humanize with Humanizer, and the rewrite is ready to paste back. Or trigger it from Spotlight. The same account and history follow you to iPhone, and every rewrite carries an AI-detector score.
Right-click to humanize
Select text in any Mac app, right-click → Services → "Humanize with Humanizer." The selection opens rewritten, ready to paste back where you were drafting.
Spotlight, no app-switching
An App Shortcut puts Humanize in Spotlight on macOS 26. Hit Command-Space, type humanize, go — no dock-hunting, no browser tab.
Built for desktop drafting
Where the long writing happens — essays, briefs, reports. Pick a mode, see the rewrite alongside an AI-detector score, and keep moving.
Same account across devices
Sign in once with Apple. Your history, personas, and subscription follow you between Mac and iPhone — draft at the desk, finalize on the phone.
An AI-detector score on every rewrite
A Sapling-based score shows how natural the output reads, so you can judge it before you submit or send.
Private by design
Inputs are processed by Anthropic's Claude under API terms and never used to train any model. Delete your account and everything is erased within 30 days.
