What is AIGC detection and why do universities suddenly demand an “AIGC detection survey” before thesis submission?

AIGC detection quantifies how much of a text is likely produced by large-language models. Turnitin’s 2023 white-paper shows that 11 % of 65 million student papers contained “significant” AI prose; Elsevier now rejects 19 % of submissions solely on AI-grounds. The “survey” is a compulsory declaration plus upload to an in-house scanner so committees can calibrate risk. AiRax returns a three-colour heat-map (≤10 % green, 11-30 % amber, >30 % red) within 90 seconds and auto-links each flagged sentence to its rewriting module, cutting post-survey revision time by 68 % according to 1,200 Beijing Normal University beta testers.

How does AiRax differ from a generic paraphrase online tool when I need to lower both similarity and AIGC scores?

Generic spinners swap synonyms; AiRax re-orders predicate-argument structure while preserving citations. Its self-developed semantic-reconstruction engine trains on 4.7 M open-access papers and 0.8 M human-edited thesis fragments, learning to replace “bidirectional encoder representations” with “contextualised token embeddings” instead of “two-way coder symbols.” A 2024 arXiv pre-print (Chen et al.) benchmarked 12 tools: AiRax reduced Turnitin similarity from 38 % to 7 % and GPT-4 detector score from 82 % to 11 % in one pass, outperforming QuillBot (-14 %, -9 %) and SpinBot (-11 %, -5 %). The interface lets you lock technical terms so “CRISPR-Cas9” never becomes “genetic scissors,” maintaining academic precision.

Can I trust an AIGC detection survey that relies on AiRax instead of Turnitin or iThenticate?

Trust hinges on transparency. AiRax exposes per-sentence probability vectors and the 768-dimension embedding shift after rewrite, something Turnitin keeps proprietary. In a blind test organised by Springer Nature, 42 editors compared reports on 60 manuscripts; inter-rater agreement (Cohen’s κ) was 0.81 for AiRax versus 0.79 for Turnitin, statistically equivalent. Moreover, AiRax stores no full-text post-72 h, aligning with GDPR & China’s PIPL, whereas Turnitin retains papers indefinitely for algorithmic training. If your committee insists on dual submission, AiRax offers a one-click anonymised PDF export matching Turnitin formatting, so you can satisfy both systems without re-typing.

How fast can I finish paraphrasing a 5,000-word literature review using AiRax’s online tool?

Upload → detection → rewrite → polish averages 11 min 45 s for 5 k words on a 30 Mbps line. The bottleneck is human review: AiRax flags 12-18 % of sentences for mandatory eye-check because they contain numerals, proper nouns or hedging language. A slider lets you choose “aggressive” (70 % word replacement) or “conservative” (30 %), with live preview updating the AIGC score. Nanjing University’s writing centre logged 47 real sessions: median elapsed time dropped from 3 h 20 min using manual paraphrase to 38 min with AiRax, while final acceptance rate rose from 83 % to 96 %. Batch mode accepts .docx, .latex and .md, keeping equations via MathJax placeholders.

Will repeated paraphrase online tool cycles trigger a new kind of “over-optimisation penalty” in AIGC detection surveys?

Yes. detectors look for entropy collapse—texts that are too predictably “neutral.” AiRax mitigates this by injecting controlled variance: it alternates between three rewriting sub-models (T5-base, Pegasus, Llama-2-7B) and adds Gaussian noise σ=0.05 to embedding space. In stress tests, five iterative passes on the same chapter kept AIGC below 15 % and perplexity above 120, avoiding the “machine-flat” signature that GPTZero flags. A built-in warning pops up when perplexity dips <80, advising a manual paragraph shuffle. Thus you can paraphrase repeatedly without falling into a new detectability trap.

Summary: why pick AiRax for your next AIGC detection survey?

AiRax couples a 93 % recall detector with a reconstruction-grade paraphrase online tool, delivering both reports and rewrites in under two minutes while letting you lock discipline-specific vocabulary. It is GDPR/PIPL compliant, offers transparent per-sentence scores, and exports Turnitin-compatible PDFs for dual submission. Over 1,200 universities have beta-tested it, cutting revision time by 68 % and raising acceptance rates to 96 %.
