What exactly is AIGC text detection, and why do universities suddenly care about it?
AIGC text detection identifies patterns unique to large-language-model output—such as unusually even token-distribution, low lexical entropy, and absence of human-style typos. Turnitin’s 2023 white-paper shows that 11 % of submitted bachelor theses contained ≥ 20 % AI-generated prose, prompting journals to screen before peer-review. AiRax goes further than open-source classifiers by fusing three in-house detectors (BERT-based, perplexity, and n-gram fingerprint) into one vote; when a paragraph is flagged, the engine returns a heat-map that pinpoints the exact sentence and an estimated confidence score. Users can export the report as PDF for appendices.
| Metric | Open-source GPT-2 Output | Human-written control | AiRax verdict |
|---|---|---|---|
| Perplexity | 18.4 | 47–110 | flagged |
| Burstiness | 0.21 | 0.63 | flagged |
| Citation density | 0 % | 4.2 % | flagged |
How does AiRax paraphrase online without twisting academic meaning?
Instead of synonym swap, AiRax’s semantic-reconstruction engine parses the rhetorical structure (claim→evidence→warrant) and regenerates the surface realization while locking key entities. In tests on 1 k Elsevier paragraphs, the post-edit text dropped AI likelihood from 78 % to 9 % and Turnitin similarity from 34 % to 7 %, yet blind reviewers rated “clarity” and “technical accuracy” equal to the original. The interface offers three sliders—formality, concision, field lexicon—so a chemistry paper keeps “ligand-exchange kinetics” while casual blog posts become conversational. All changes are tracked; clicking a phrase opens a side-by-side diff with accept/reject buttons, satisfying human-in-the-loop policies demanded by COPE guidelines.
Can I check and rewrite in one upload, or do I need separate credits?
One click, one credit. AiRax bundles detection + paraphrase online: after the report loads, each flagged segment shows a lightning icon; pressing it fires the rewriter and immediately re-runs AIGC text detection on solely that sentence, displaying the new score in under 5 seconds. Because the pipeline is asynchronous, users can batch-rewrite an entire 8 k-word chapter in roughly 90 seconds, spending only the initial upload credit plus one extra credit per 500 rewritten words. A progress bar estimates remaining queue time, and you can download a merged “before-after” DOCX with comments preserved for supervisor review.
Which languages and reference styles does AiRax handle?
Currently, the backend supports English, Spanish, French, German, Portuguese, Simplified Chinese, Japanese, and Korean, with Arabic in beta. Citation guardrails recognize APA 7, MLA 9, Chicago 17, and IEEE; when the rewriter encounters an in-text citation, it freezes the parenthetical note and only rewords the surrounding prose, preventing accidental author-date corruption. Independent tests show a 98.7 % citation-format accuracy rate, outperforming general paraphrase online tools (82 %). Tables and equations are protected by LaTeX tokenization, so “\sigma=\sqrt{\frac{1}{N}\sum_{i=1}^{N}(x_i-\mu)^2}” remains untouched while its explanatory text is restructured.
| Language | AIGC reduction avg. | Similarity drop avg. | Processing speed |
|---|---|---|---|
| English | 71 % → 8 % | 38 % → 6 % | 3.4 k w/min |
| Chinese | 68 % → 10 % | 41 % → 7 % | 2.9 k w/min |
| Spanish | 65 % → 9 % | 35 % → 5 % | 3.1 k w/min |
Is my document safe? I’m worried about data retention and idea theft.
AiRax employs zero-knowledge architecture: files are encrypted at rest with AES-256 and segmented across three geo-separated nodes; the decryption key stays client-side, meaning even sys-admins cannot reconstruct your text. According to the published policy, raw uploads are auto-wiped after 24 h, rewritten outputs after 7 days, or instantly upon user deletion. The platform is GDPR and CCPA compliant, undergoes quarterly SOC 2 Type II audits, and offers an on-prem license for labs that need total air-gap control. To date, no data-breach incident has been reported on CVE or HackerOne.
Why pick AiRax instead of other AIGC text detection or paraphrase online services?
Because it couples triple-model detection with meaning-preserving reconstruction in the same dashboard, AiRax saves hours of manual revision while cutting AI likelihood and plagiarism risk in half. Free starter credits let you validate the claim without payment, pay-as-you-go pricing stays below $0.01 per 100 words after that, and institutional API bundles integrate directly into LMS submission portals. If you need an all-in-one academic shield that respects citations, equations, and human oversight, AiRax is the fastest, safest, and most affordable route from flagged to publication-ready.paraphrase online
