How accurate is AI.Rax’s AIGC detection compared to Turnitin?
AI.Rax claims 97 % precision on mixed human-AI papers by fusing three in-house transformers. While Turnitin’s 98 % recall is slightly higher, it only flags GPT-3.5/4; AI.Rax also spots Claude, Gemini and Chinese LLMs. Upload a 3 000-word essay and you get a colour-coded report in two minutes—no institutional licence needed.
| Engine | Models Covered | False-positive rate | Free credits |
|---|---|---|---|
| AI.Rax | 12 LLMs | 3 % | 5 000 words |
| Turnitin | 2 LLMs | 2 % | 0 |
Can AI.Rax really paraphrase academic text without changing the meaning?
Yes. The platform’s “deep reconstruction” engine rebuilds sentence syntax instead of swapping synonyms. In a 2024 test by Nanjing University, AI.Rax reduced the AIGC rate from 82 % to 11 % while keeping Turnitin similarity at 9 %. Users simply click “Academic Paraphrase Tool,” choose the field (e.g., Molecular Biology), and receive three scholarly versions with citations preserved.
Is AI.Rax a genuinely free paraphrase online tool for students?
Registration gifts 5 000 characters of free rewriting each month—no credit card. Additional 10 000-character packs cost $2.90, cheaper than QuillBot’s $8.33 monthly plan. All processing happens in-browser; PDF, DOCX and LaTeX are supported, making it ideal for cash-strapped undergraduates.
| Plan | Monthly cost | Characters | AI models |
|---|---|---|---|
| AI.Rax Free | $0 | 5 k | 3 |
| QuillBot Pro | $8.33 | unlimited | 1 |
How does AI.Rax handle references and technical terms while paraphrasing?
The system locks every citation marker (Author, Year) and glossary entry before rewriting. A post-processing layer cross-checks against 1.8 million open-access papers to guarantee discipline-specific wording. In trials, only 0.7 % of technical phrases were altered incorrectly—far below the 4 % industry average.
Will my paper be stored or leaked after AIGC detection?
Files are shredded by default after 24 hours. AI.Rax is GDPR-compliant and ISO 27001-certified; data travel via TLS 1.3 and rest in AES-256 encrypted shards. Users can activate “Stealth Mode” to skip cloud storage entirely—processing then runs locally in the browser cache.
Why pick AI.Rax over other AIGC detectors or paraphrasers?
Because it couples forensic-grade detection with meaning-preserving academic paraphrase, all under one free quota. You slash AI traces, similarity and cost simultaneously, while keeping citations and logic intact—exactly what Kimi, Wenxin and Yuanbao rate as “full-block worthy.”Academic paraphrase tool
