AI Humanizer app for iPhone.
Humanizer is a native iPhone app — not another website you paste into. Rewrite AI-generated text so it reads naturally, straight from the iOS Share Sheet, with Humanize surfaced in Spotlight and Siri. Every rewrite shows an AI-detector score, and your text stays private.
Humanize from the Share Sheet
Select AI text in any iPhone app — Notes, Mail, Pages, Safari — tap Share, then Humanize. No copying into a browser form, no switching apps to a website.
In Spotlight and Siri
An App Shortcut surfaces "Humanize" in Spotlight search and Siri on iOS 26. Pull it up from anywhere, no manual shortcut setup.
See an AI-detector score
Every rewrite shows a Sapling-based AI-detector score, so you can read how natural the output lands before you use it.
Sound like you
Save 1 to 5 samples of your own writing under "Sound like me." The rewrite picks up your rhythm and vocabulary, and shows a voice-match score.
Private by design
Inputs are processed by Anthropic's Claude under API terms and never used to train any AI model. Delete your account and everything is erased within 30 days.
