## Principais recursos e capacidades

- **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.

## Principais casos de uso

- **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.

## Pontos fortes

- 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

## Limitações

- 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
