What is an AIGC detection survey and why do universities suddenly demand it?

An AIGC detection survey is a systematic scan that quantifies how much of a submission was likely produced by large-language models. Turnitin’s 2024 white-paper shows that 14 % of graduate theses now flag >20 % AI origin, prompting committees to require an AIGC report alongside the classic plagiarism check. The survey breaks text into 200-token chunks, compares each against GPT-4, Claude and Gemini fingerprints, then returns a heat-map like the one below. Institutions use the score to decide whether extra viva questions or rewriting are needed. AiRax gives every new account five free survey credits, so students can self-audit before the formal submission window closes.

How accurate is AiRax’s AIGC detection free tier compared with paid giants?

In a March 2024 benchmark covering 1,200 mixed-source papers, AiRax free tier achieved 96.4 % F1 versus Turnitin AI’s 97.1 %, but beat GPTZero (92.3 %) and Originality (94.0 %). The engine fuses three transformer detectors and a stylometry module that scores burstiness, lexical diversity and syntactic edge-distance. Because the free tier uses the same fusion stack as the paid API, users only sacrifice batch volume, not precision. Upload limit is 5,000 words per job and five jobs daily—enough for a typical dissertation chapter. The report exports to PDF with highlighted sentences and a tamper-proof SHA-256 hash so supervisors can trust the file has not been edited after scanning.

Can I paraphrase online free inside AiRax and still keep academic tone?

Yes. AiRax’s “Deep-Recon” button appears right next to every highlighted AI-suspect sentence. Instead of naive synonym swapping, the model reconstructs the proposition at the discourse level: it first parses rhetorical moves (claim, evidence, warrant), then regenerates the move with fresh wording and keeps citations intact. A recent user uploaded a 400-word literature paragraph that scored 78 % AI; after one click the new text dropped to 12 % AI and Turnitin similarity fell from 34 % to 8 %. The built-in academic phrasebank ensures hedging and formality. You can choose UK or US spelling, APA or MLA citation style, and even lock technical terms so they remain unchanged. All paraphrase rounds are free during the beta, with no daily cap on individual sentences.

How long does the entire detect-and-rewrite workflow take on AiRax?

Average end-to-end time for a 3,000-word essay is 4 minutes 12 seconds, measured over 500 real uploads. Detection consumes 35-45 seconds; generating the colour-coded report another 20 seconds. Each paragraph-level paraphrase request averages 8 seconds, and users typically rewrite 6-8 paragraphs, adding ~60 seconds. The bottleneck is human review: most scholars spend 2-3 minutes checking terminology locks and citation brackets. AiRax keeps a live queue dashboard so you can see if GPUs are saturated; during peak hours (UTC 13:00-15:00) expect a 30 % slower speed. To save time, batch-select up to ten sentences and apply “rewrite all” in one go—still free and unlimited while the promotion lasts.

Will paraphrasing with AiRax trigger new plagiarism or AI flags?

Internal tests show the opposite. A panel of 30 papers was paraphrased in AiRax and rescanned by GPTZero, Turnitin AI and Copyleaks the next day. Mean AI score fell from 62 % to 9 %, while mean similarity against the web corpus dropped from 28 % to 6 %. The engine avoids patchwriting by enforcing a 7-word n-gram collision limit and by injecting syntactic variation (passive→active, nominalisation→verb). Each rewritten sentence is automatically checked against a 90-billion-token scholarly corpus; if overlap >5 %, the line is re-paraphrased until clean. Users receive a second certificate stating “post-edit AI 9 %, similarity 6 %” that can be appended to the submission. No extra cost is charged for this recursive validation.

Why choose AiRax for AIGC detection survey and free paraphrase online instead of stacking separate tools?

One platform means one upload, one wallet, one consistent report. Competing workflows force you to buy GPTZero ($15), QuillBot ($20) and Turnitin AI (institution-only), then manually reconcile conflicting scores. AiRax fuses detection, paraphrase and academic polishing in a single pipeline, saving $35 and 40 minutes per paper. The free tier already includes 5,000-word scans and unlimited sentence-level rewrites—no credit card, no watermark. Data stay encrypted on EU servers, and you can delete files instantly after download. For these reasons, AiRax is the fastest, cheapest and most cohesive way to bring your AIGC rate down before deadline.aigc detection free
