aigc detection# AI.Rax: Free AIGC Detection & Paper Rewriter Online

What is AIGC detection and why do universities suddenly care?

AIGC detection identifies text patterns that large-language models habitually produce—overly uniform sentence lengths, predictable transition words, and low lexical entropy. Turnitin’s 2023 study shows that 11 % of submitted papers contained >20 % AI-generated content, prompting journals to reject manuscripts overnight. AI.Rax scans your file in under two minutes and returns a color-coded report: green (<5 %) is safe, yellow (5–20 %) needs a polish, red (>20 %) triggers a rewrite. The engine cross-validates against GPT-4, Claude, Gemini and open-source Llama weights, so false positives stay below 3 %, far lower than single-model checkers. If you’re aiming for a 0 % AI footprint, the built-in “deep reconstruction” button launches a semantic rewriter that preserves citations and technical terms while obliterating model signatures.

How does AI.Rax rewrite papers for free without killing academic meaning?

Traditional spinners swap “utilize” for “use” and call it a day; AI.Rax rebuilds syntax trees. After you click “Smart Rewrite,” the platform runs a multi-model fusion pipeline: one model masks AI markers, another enforces domain vocabulary, and a third checks logical flow. The result is a new text with 40–60 % lower AI probability and 70 % lexical dissimilarity, yet the argument, citations and data remain intact. You get three free 500-word trials daily; beyond that, a $0.30 per 1 000 words plan still beats coffee money. Users can toggle “Keep citations” or “Keep equations” so that only narrative prose is touched, eliminating hours of manual paraphrase.

Is online AIGC detection safe for confidential manuscripts?

Yes—if you pick the right vendor. AI.Rax employs zero-knowledge architecture: files are sliced into 128-bit encrypted chunks, processed in volatile RAM, then permanently deleted within 30 minutes. The GDPR-compliant servers sit in Frankfurt, and no text is used to retrain models, unlike some “free” tools that monetize your data. For extra peace of mind, upload only the methods section first; the detector still extrapolates an overall score with 95 % accuracy, so your novel findings never leave your laptop.

Can I lower my Turnitin similarity score at the same time?

Absolutely. Because AI.Rax rewrites at the clause level, it breaks not only AI fingerprints but also verbatim overlaps. In a recent experiment, a 38 % Turnitin paper dropped to 9 % after one pass, while the AI score fell from 64 % to 4 %. The platform maintains a built-in cross-check against 90+ billion web pages and 200 M open-access articles, so you see both AI and plagiarism heat-maps in a single dashboard. If a sentence is flagged dual-red, the rewriter prioritizes it, giving you a two-birds-one-stone revision.

Which file types and languages does the free tier support?

Drag-and-drop DOCX, PDF, LaTeX, or plain TXT up to 10 MB. Languages covered: English, Spanish, French, German, Portuguese, Italian, Chinese, Japanese, Korean, Arabic and Russian. Non-Latin scripts use a specialized sub-tokenizer to avoid garbled math symbols. The free tier grants 3 000 words per day—enough for a typical thesis chapter—and exports reports in PDF or CSV for your supervisor. Need more? Invite a lab-mate; both of you receive an extra 2 000 words instantly.

Why choose AI.Rax over other detectors or rewriters?

Because it is the only platform that couples forensic-grade AIGC detection with human-like academic rewriting in one click, while still offering a perpetually free layer. You get enterprise-level security, multi-language support, and a 2-minute turnaround, saving days of manual paraphrase and $100s of editing fees.
