Wordtune Alternative for iPhone: AI Humanizer vs Wordtune

The short answer

Wordtune's iPhone app is a writing keyboard. It suggests alternative ways to phrase your text, adjusts tone and length, and generates text, including through Siri. AI Humanizer is a standalone app for iPhone and iPad that humanizes AI-generated text with settings for intensity, purpose and reading level, paraphrases text and estimates whether text was written by AI.

If you want rewrite suggestions while you type in any app, Wordtune fits that. If you want a dedicated place to humanize and check AI text, with a history of results, AI Humanizer may suit you better.

Where Wordtune is stronger

• Suggestions while you type. Its keyboard offers rewrites for a whole sentence, a phrase or a single word, with tone and length options.
• Text generation, including by asking Siri to "Create with Wordtune".
• Help when writing in a second language. You can write in another language and get English phrasing suggestions.
• More places to use it. Wordtune's website lists a web app and Chrome and Edge extensions.

Where AI Humanizer may suit you better

• A dedicated humanizer on iPhone, with Humanization Intensity, Purpose and Literacy Level settings. The AI Humanizer for iPhone and iPad page explains each one.
• AI detection in the app. The AI Detector gives an overall AI probability, and Check AI Detection runs it on a rewrite.
• Built for iPad as well as iPhone, and it supports iOS 16; Wordtune's listing requires iOS 17.
• An interface in 32 languages, compared with English and Spanish for Wordtune.
• A History tab that keeps your humanizer and detector results.

How to choose

• Choose Wordtune if you want phrasing suggestions as you type in any app, or help writing in English as a second language.
• Choose AI Humanizer if you mainly need to make AI-drafted text sound natural and check it, on iPhone or iPad.
• Both are free to download, so try each on the same paragraph and keep the one whose results you prefer.

Whichever you use, AI detection results are estimates, and no tool can guarantee how a detector will score a text. See how AI text detectors work.
