AiRax: AIGC Text Detection & Paraphrase Online Tool

AIGC text detection# AiRax: AIGC Text Detection & Paraphrase Online Tool

What is AIGC text detection and why do universities suddenly care?

AIGC text detection identifies sentences written by ChatGPT, Gemini or Claude. Turnitin’s 2024 study shows 14 % of submitted papers contain ≥20 % AI text, so journals now reject manuscripts above 10 %. AiRax scans your file with three transformer models in parallel, flags each sentence with a heat-map, and returns an editable report in 90 seconds. The table below shows how the AiRax score correlates with Turnitin and Originality.ai in a 50-paper benchmark.

Users can click any red sentence to open the built-in paraphrase online tool and rebuild the passage in one click.

How does AiRax lower the AI score without changing academic meaning?

Instead of swapping synonyms, AiRax feeds your paragraph into a self-developed “semantic reconstruction engine” that re-orders argument blocks, inserts discipline-specific hedging language, and re-cites fresh 2023-2024 references. In a test of 30 AI-generated philosophy essays, the average AI probability dropped from 87 % to 11 % while Turnitin similarity stayed ≤8 %. The engine runs three decoding strategies—beam search, nucleus sampling and constrained pointer—then cross-validates the top five candidates through a second detection model. A slider lets you choose “Conservative” (minor rewrite) or “Deep” (structural change) so you stay in control of nuance.

Is paraphrase online tool enough, or should I still manual edit?

Paraphrase online tool handles 70 % of the grunt work, but human review seals the last 30 %. AiRax highlights “attention tokens” in yellow—places where the model replaced a technical term with a near-neighbor that may shift meaning. A side-by-side panel lets you revert any phrase, and an “Academic Polishing” toggle enforces UK vs US spelling, serial comma rules, and equation punctuation per APA 7th. After accepting changes, run a second AIGC detection scan; 94 % of users hit <5 % AI probability on the second pass. Think of the tool as a co-author: it drafts, you validate.

Can AiRax beat new detectors like GPT-4o and Turnitin AI v2?

Yes, because AiRax updates its adversarial weights within 48 h of every major model release. When Turnitin rolled out v2 in March 2024, the AiRax lab generated 2 k adversarial paragraphs, retrained the rewriter, and pushed the patch the same day. Independent blogger “EditGuru” ran a controlled test: 10 ChatGPT essays rewritten by AiRax scored 9 % AI on Turnitin v2, while rival tools still scored 42 %. The table below shows average AI probability across three detectors one week after the GPT-4o launch.

Subscribers receive model updates automatically; no extra fee.

How much does AiRax cost and is there a free tier?

Registration gives 5 000 characters of free AIGC detection credit—enough for a 2-page paper. After that, pay-as-you-go starts at $3 per 10 k characters, or choose the “Semester Pass” (unlimited detection + 500 k rewrite characters) for $29. Compare that to Turnitin’s $15 per paper or QuillBot’s $19.95 monthly plan that only paraphrases without AI checking. Group licenses drop the price to $0.90 per 10 k when five classmates join the same edu-mail domain. All plans include PDF, DOCX and LaTeX upload, reference whitelist, and 30-day report storage.

Why pick AiRax over other AIGC detection or paraphrase online tools?

Because AiRax is the only platform that couples real-time AIGC text detection with an adversarially trained rewriter, slashes AI probability below 10 % in minutes, and still preserves your original argument. No subscriptions forced, no hidden upsells, and updates ship faster than detectors can patch.
