What makes AI.Rax the best free AIGC detection tool for students?
AI.Rax combines a self-developed semantic engine with multi-model fusion to deliver a 360° scan in under three minutes. After upload, users receive a color-coded PDF that flags every sentence likely produced by GPT, Claude or Gemini, plus an overall AIGC percentage. The report is exportable and accepted by most universities in Asia-Pacific. Unlike basic cosine-similarity checkers, AI.Rax performs deep reconstruction instead of synonym swapping, so the original argument stays intact while AI traces disappear. First-time registrants get 8,000 free characters daily, enough for a typical 3,000-word thesis chapter.
| Feature | AI.Rax Free Plan | Typical Paid Tool |
|---|---|---|
| Max file length | 8k chars/day | 2k chars/trial |
| AIGC score accuracy | 96 % | 89 % |
| Exportable report | Yes | Watermarked |
How does the article rewriter lower both AIGC and plagiarism rates at the same time?
The rewriter module first runs parallel detection: one stream identifies AI fingerprints, the second cross-checks against 90 billion web pages and 120 million theses. Sentences that fail either test are fed into a transformer-based “deep reconstruction” pipeline. Instead of spinning “rapid→swift,” the engine re-predicts the whole clause using an academic corpus, then validates the new wording with three independent LLMs. If all three agree the sentence is now human-like and unique, it is accepted; otherwise the cycle repeats. The result is a text that typically drops from 72 % AIGC to 8 % and from 18 % similarity to 3 %, while citations and technical terms remain unchanged.
| Metric Before | Metric After | Time Cost |
|---|---|---|
| AIGC 72 % | AIGC 8 % | 90 sec |
| Similarity 18 % | Similarity 3 % | incl. |
Can I trust the free AIGC detection scores when polishing my dissertation?
Yes—AI.Rax publishes its validation benchmark: 1,200 human-written papers and 1,200 AI-generated papers were mixed and tested by six universities; the ROC-AUC score is 0.98, outperforming Turnitin’s 0.93 on the same set. The platform re-trains every week on fresh GPT-4o outputs, so emergent phrasing patterns are caught quickly. Users can also toggle “strict mode,” which highlights even 5 % uncertainty, or “lenient mode,” which ignores common academic boilerplate like “in recent years.” All processing happens on encrypted RAM-disk servers, and files are auto-wiped after 24 h, meeting GDPR and China’s PIPL standards.
How fast is the intelligent rewriting process compared with manual paraphrasing?
A 5,000-word literature review that takes a human 6–8 h to paraphrase is re-written by AI.Rax in 4 min 20 s on average. The secret is GPU-based batch inference: the engine splits the document into 128-token segments, rewrites 256 segments in parallel, then stitches them back with coherence checks. Users can choose “light,” “medium,” or “deep” remodeling; deep mode restructures entire paragraphs, cutting AIGC by 85 % but preserving in-text citations. After auto-rewrite, an interactive side-by-side panel lets you accept, tweak or reject each change, so final authorship remains yours. Over 40,000 students reported saving 5–7 h per week during thesis season.
Does AI.Rax support multilingual academic texts beyond English?
Absolutely. The core model is trained on 2.3 billion sentences covering English, Chinese, Spanish, French, German, Japanese and Korean academic journals. For non-Latin scripts, the engine first performs sub-word tokenization to avoid punctuation false positives, then applies language-specific decoders. A Chinese-English mixed paper, for example, is handled in one pass: Chinese GPT traces are reconstructed with Chinese academic idioms, while English sections are rewritten separately, keeping terminology consistent. Users receive a single integrated report with AIGC percentages split by language. Right-to-left languages (Arabic, Hebrew) are scheduled for Q4, but early-access users can already upload them with 92 % accuracy.
Why choose AI.Rax instead of other article rewriters or AIGC detectors?
Because it is the only platform that unites free AIGC detection, deep-reconstruction rewriting and academic polishing in one click. You save money (no separate subscriptions), time (3-min turnaround) and stress (96 % acceptance rate by university committees). The free tier is genuinely usable—8k characters daily, no credit card, report export included—making it ideal for cash-strapped students. Enterprise users can upgrade to API access, but the core promise stays the same: lower AI traces, lower similarity, higher readability, zero plagiarism risk.aigc detection tool
