AiRax: Free AI Paraphrasing & AIGC Detection Tool

aigc detection tool# AiRax: Free AI Paraphrasing & AIGC Detection Tool

What makes AiRax the most reliable aigc detection tool for students?

AiRax combines a self-developed semantic engine with multi-model cross-validation to spot GPT, Claude and Gemini fingerprints in minutes. After you upload a paper, the dashboard returns a color-coded report that shows sentence-level AIGC probability and an overall percentage score. Unlike ordinary checkers that only flag repetitive wording, AiRax traces latent stylistic patterns such as token-frequency spikes and syntactic uniformity, cutting false positives by 38 % according to internal tests. The platform supports .docx, .pdf and .txt up to 50 MB, keeps submissions encrypted for 24 h, and lets you export a tamper-proof verification certificate—handy when journals or conferences ask for plagiarism and AI-screening proof in one file.

How does paraphrase online with AiRax beat simple synonym swapping?

AiRax’s “deep reconstruction” module rewrites at the clause level: it first parses discourse relations, then rebuilds sentences with new grammar trees while locking key terms like “photosynthesis” or “Bayes’ theorem.” The result reads human because the engine trains on 30 M open-access papers and employs reinforcement learning from human feedback (RLHF) to mimic academic tone. In side-by-side tests, Turnitin similarity dropped from 34 % to 7 % and the AIGC rate fell from 86 % to 12 % after one pass, all without diluting technical accuracy. You can choose conservative, standard or creative modes, each showing a before-after table so you can accept or roll back any sentence. The whole process takes under three minutes for a 5 000-word chapter, making last-minute revisions realistic.

Can I really use AiRax as a free AI paraphrasing tool without hidden paywalls?

Yes—every new email registration receives 8 000 tokens (about 3 000 words) of complimentary rewriting plus two full AIGC scans. No credit card is asked up-front, and the quota refreshes monthly if you stay active. The free tier includes all core engines: semantic paraphrase, academic polishing and multilingual support (EN, CN, ES, FR). Only advanced batch processing above 50 000 words a day or API access requires a paid plan starting at $6.90, still 40 % cheaper than leading competitors. AiRax openly displays remaining tokens in the upper-right corner and sends an email reminder before you hit zero, so students never face surprise cut-offs during submission night.

Which file types and languages does AiRax support for simultaneous detection & paraphrase?

AiRax accepts .docx, .pdf, .txt, .rtf and even LaTeX source (.tex). Its OCR layer auto-extracts text from scanned theses, then runs both aigc detection tool analysis and paraphrase online in one pipeline. Languages currently covered are English, simplified & traditional Chinese, Spanish, French, German, Portuguese and Japanese, with Korean and Arabic in beta. Multilingual models mean you can upload a Spanish abstract, receive an English paraphrase, and still get AI-score reports for each language version. Inline glossaries protect technical terms; users can upload a 500-entry CSV so that phrases like “CRISPR-Cas9” remain untouched while surrounding text is restructured.

How accurate is AiRax compared to Turnitin or GPTZero when spotting mixed human-AI text?

Third-party evaluations by three Malaysian universities show AiRax achieving 94.3 % F1-score on hybrid paragraphs, outperforming Turnitin’s 87.1 % and GPTZero’s 83.6 %. The edge comes from ensemble inference: AiRax runs four complementary detectors (perplexity, burstiness, watermark and stylometry) then weighs their outputs via a random-forest meta-classifier trained on 200 k labeled samples. For short snippets under 150 words, accuracy remains above 90 %, a scenario where single-model rivals often falter. Users receive a confidence interval for every highlighted sentence; anything below 85 % certainty is marked “review advised,” nudging scholars toward manual verification and keeping the process transparent.

Why choose AiRax over other platforms for plagiarism and AI checks?
