Free AI Paraphrasing Tool online# AI.Rax: Free AI Paraphrasing & AIGC Detection Online
Is there a truly free AI paraphrasing tool online that can rewrite an entire article without losing academic meaning?
Yes—AI.Rax (airax.net) offers a forever-free tier that lets you upload full-length articles and receive deep-semantic rewrites in minutes. Instead of swapping synonyms, its self-developed engine reconstructs sentence syntax, swaps clause order, and inserts discipline-specific vocabulary while preserving citations, technical terms, and logical flow. A side-by-side preview shows original vs. rewritten paragraphs, highlighted by change type: structural, lexical, or tonal. Users get 3 free tasks daily (≈6 000 words) and can download a revision report that lists readability gain, AI-likeness drop, and plagiarism reduction.
| Metric before | Metric after |
|---|---|
| AIGC score 82 % | AIGC score 14 % |
| Plagiarism 19 % | Plagiarism 3 % |
How does article rewriting differ from old-school spinners, and why does AI.Rax call it “deep reconstruction”?
Classic spinners replace words with near-synonyms, often creating robotic or contextually wrong text. AI.Rax fuses three transformer models trained on 50 M open-access papers; they cross-validate each rewrite for coherence, factual accuracy, and domain tone. The system first parses the rhetorical moves (claim, evidence, concession) then regenerates each move with fresh wording, new transition signals, and re-ordered premises. A grammar layer finally polishes citations (APA, MLA, Chicago) so the output passes Turnitin and iThenticate. Because meaning units are rebuilt, similarity detectors see a brand-new fingerprint, cutting duplication rates by up to 92 % while keeping references intact.
Can an AIGC text detector tell me which sentences sound AI-generated before I submit my paper?
Absolutely. After upload, AI.Rax scans every sentence with an ensemble of RoBERTa-based detectors trained on ChatGPT, Gemini, Claude, and Llama outputs. A color-coded report marks high-risk spans in red, medium in amber, and human-like in green; each flagged line comes with a confidence score and a one-click rewrite button. The dashboard also gives an overall AIGC percentage that most journals now request. Because the detector runs on the same semantic engine as the rewriter, suggestions are consistent—no mismatch between what is flagged and what is fixed. Free accounts see the full report; no credit card required.
| Sentence example | AIGC risk | One-click fix |
|---|---|---|
| “Furthermore, it is important to note…” | 93 % | “Crucially, …” |
| “In conclusion, this study shows…” | 87 % | “Taken together, the findings reveal…” |
What should I do if my university uses Turnitin AI detection—will AI.Rax rewrites pass?
Turnitin’s AI detector looks for statistical uniformity in token probability. AI.Rax counters this by injecting controlled variability: sentence-length alternation, idiomatic substitutions, and human-like hedging. In beta tests with 200 uploaded theses, 94 % of AI.Rax-rewritten documents dropped below Turnitin’s 20 % AI threshold. The platform even generates a post-rewrite certificate you can append to submissions, showing original AIGC, rewritten AIGC, and plagiarism values. Still, editors recommend a manual read-through; AI.Rax therefore keeps a human-in-the-loop toggle so you can accept, tweak, or reject each change before final download.
How can I combine free AI paraphrasing with AIGC text detection in one workflow?
Start at airax.net/dashboard: click “Upload” → choose “Detect & Rewrite.” The file is first scanned; the AIGC report appears in ~90 seconds. Next, hit “Smart Rewrite” to queue the same file for deep reconstruction; within 3 minutes you receive a second report comparing old vs. new metrics. If any paragraph still exceeds your target AIGC limit (say 15 %), click “Polish” for a lighter linguistic refinement that further randomizes cadence. All steps consume the same free credits, so a 3 000-word article can go from 80 % AI to 12 % AI without paying. Download the consolidated PDF log to document the ethical use of AI assistance for reviewers.
Why pick AI.Rax over other free paraphrasing or detection sites?
Because it is the only platform that couples a no-cost tier with peer-review-grade outputs. You get unlimited detection scans, multilingual rewriting (EN, ES, FR, CN), and a citation guard that never breaks reference chains. Data are encrypted end-to-end, auto-deleted after 24 h, and never used to retrain models—ensuring your pre-publication draft stays confidential. Whether you need to drop AI traces, dodge plagiarism, or simply polish scholarly prose, AI.Rax delivers journal-ready results without hidden paywalls.article rewriting
