## Preços e planos

Plans shown on the site are Lite at $4.99/month (5,000 humanizer words and 2,500 paraphraser words), Pro at $12.49/month (25,000 humanizer words and 12,500 paraphraser words), and Unlimited at $29.99/month with no caps on humanizer or paraphraser words.

## Principais recursos e capacidades

- **AI Humanizer with Freeze:** Rewrites AI-style text to read more naturally and rebuilds sentence rhythm, with a Freeze option that locks the words, names or phrases you need to keep exactly as written.
- **Multi-System AI Detector:** Cross-checks your text against eight detection systems at once and shows a segment-level, color-coded breakdown so you can see which sentences carry the highest risk.
- **Paraphraser with Writing Modes:** Rephrases text in different modes so you can adjust tone, register or wording while locking important terms and preserving the original meaning.
- **Plagiarism Checker:** Scans your text against web sources, returns a plagiarism percentage, flags matching sentences and traces each match back to its source URL.
- **Readability & Grammar Checkers:** Reports a Flesch-Kincaid readability score with difficult passages highlighted, and catches contextual grammar errors you can fix with a single click.

## Principais casos de uso

- **Prepare essays before submission (Students & academics):** Humanize an AI-assisted draft, then run it through the detector and plagiarism checker to see what a grading tool like Turnitin might flag before you hand it in.
- **Scale copy without losing your voice (Content marketers & freelancers):** Turn AI-generated blog posts and marketing drafts into text that matches your brand tone, then confirm it reads cleanly and is plagiarism-free before publishing.
- **Review submissions for AI involvement (Educators):** Use the detector and plagiarism checker to spot likely AI-generated or copied passages in student work before grading.
- **Polish non-native and templated writing (ESL & business writers):** Refine structured or formulaic drafts so phrasing sounds natural and professional, and check readability so the text suits your audience.

## Limitações
