## 總覽

uPass AI is a student-focused AI humanizer and checker. It rewrites AI-generated text into natural, human-sounding prose, then lets you test the result against multiple AI detectors in one run.

## 價格與方案

Freemium. The free plan gives 300 words per month for both the humanizer and the detector. Paid tiers: Basic $14.99/month (5,000 words/month, up to 500 words per input), Pro $19.99/month (30,000 words/month, up to 1,000 words per input) and Unlimited $79.99/month (unlimited words). Yearly billing discounts the paid monthly prices.

## 關鍵功能與能力

- **AI humanizer with three intensity modes:** Paste AI-written text and uPass rewrites it with vocabulary and sentence structures that read like a person wrote it, rather than simple synonym swapping.
- **Multi-detector AI checker:** Check a passage against several popular detectors in a single run instead of submitting it to each service separately, and see where your text stands.
- **Basic, Advanced and Aggressive settings:** Select Basic, Advanced or Aggressive depending on how much restructuring the text needs while keeping the meaning intact.
- **Plagiarism-conscious rewriting:** The rewriter generates varied phrasing designed to keep output free of matches flagged by plagiarism checkers as well as AI detectors.
- **Multilingual support:** The humanizer accepts and outputs text in more than fifty languages, with a browser interface localized into many of them.

## 主要使用情境

- **Review an essay for AI-detection risk (University student):** Run a draft through the multi-detector checker before submitting, then humanize the passages that score as machine-written.
- **Polish AI-assisted literature notes (Graduate researcher):** Use the humanizer to rework awkward, repetitive machine phrasing while keeping the original meaning and citations intact.
- **Rework marketing copy into natural prose (Content marketer):** Rewrite AI-drafted captions and product text into more natural phrasing and run it through the detector to spot passages that need another pass.
- **Humanize non-English drafts (Multilingual writer):** Use the rewriter's 50+ language support on non-English drafts and correct phrasing that sounds translated.

## 優勢

- Detector and humanizer live in one interface, with one consolidated detection report
- Free tier is enough to judge output quality before paying
- Three rewriting intensities let you tune how far the text moves from the source
- Supports more than 50 languages
- Credits, word limits and per-input ceilings are stated openly on the pricing page

## 限制

- Free plan is very limited at 300 words per month
- Humanizer output still needs a human proofread for accuracy in technical subjects
- Results against any given detector can change as detectors update
- Using it may conflict with the academic integrity rules of some institutions

## 常見問題

### What is uPass AI?
It is a writing tool with two parts: an AI humanizer that rewrites AI-generated text into more natural prose, and an AI detector that checks text against several detection services at once so you can judge its AI-detection risk.

### How much does uPass AI cost?

### Which detectors does it claim to bypass?
The site states it is tested against Turnitin as well as GPTZero, Originality.ai, Copyleaks, ZeroGPT, Sapling, Writer, QuillBot and Crossplag. Detector algorithms change frequently, so results can vary over time and should be verified on your own text.

### What are the humanization modes?
Three modes — Basic, Advanced and Aggressive — trading off how heavily the text is restructured against how closely it stays to the original phrasing. Basic stays closest to the source; Aggressive changes the most sentence structure.

### Can I use the output for a graded assignment?
You are responsible for how you use it. The tool's output passes AI and plagiarism checks, but many schools treat AI-assisted writing as an integrity violation, so check your institution's policy before relying on it.
