# Humanit — Free AI Humanizer & AI Writing Toolkit

> Humanit (https://humanit.app) is a free AI humanizer and AI writing toolkit. It rewrites AI-generated text from ChatGPT, Gemini, or Claude to read like natural human writing (built to bypass GPTZero, Turnitin, Originality.ai, and Copyleaks), and bundles an AI detector, paraphraser, summarizer, and grammar checker. Free every day, no sign-up to try. Also a native iOS app.

## The five tools

### AI Humanizer — https://humanit.app/humanize

To humanize AI text means to rewrite AI-generated writing so it reads like a person wrote it — varying sentence length, cutting AI-tell phrases, and restoring natural voice while keeping the meaning intact.

### AI Detector — https://humanit.app/detect

An AI detector estimates the probability that text was generated by an AI model, scoring signals like perplexity, burstiness, and AI-tell vocabulary to return a 0–100 AI score, a verdict, and the specific sentences that read as machine-written.

### Paraphraser — https://humanit.app/paraphrase

A paraphrasing tool rewrites text using different words and sentence structures while keeping the original meaning — useful for clarity, tone changes, and avoiding repetition.

### Summarizer — https://humanit.app/summarize

A text summarizer condenses long content into a shorter version that keeps the key facts and main points — available as a short TL;DR, a paragraph, bullet points, or key takeaways.

### Grammar Fix — https://humanit.app/grammar

A grammar checker scans your text for grammar, spelling, and punctuation errors and corrects them — Humanit also explains why each change was made, so you learn from every fix instead of just accepting it.

## How the humanizer works

AI detectors score two signals most heavily: perplexity (how predictable word choice is) and burstiness (how much sentence length varies). AI text tends to be low on both. Humanit raises both — varying sentence length aggressively, breaking rule-of-three list patterns, cutting stock AI-tell vocabulary (delve, tapestry, leverage, moreover, robust, seamless), and restoring natural human voice. Ultra mode restructures clauses rather than swapping words, producing the most human-like output. No tool guarantees 100% across every detector version, so a built-in detector lets you verify before you submit.

- **Product:** Humanit — AI humanizer, AI detector, paraphraser, summarizer, and grammar checker.
- **Free tier:** 3 runs/day, up to 500 words per run, no sign-up to try.
- **Privacy:** text is processed to return your result and is never used to train any AI model.
- **Honest framing:** no humanizer guarantees 100% across every AI detector version; detection is probabilistic, so Humanit pairs the humanizer with a built-in detector to verify results.
