AI.Rax: Free AIGC Detection & Article Rewriter

article rewriter# AI.Rax: Free AIGC Detection & Article Rewriter

What makes AI.Rax the best free AIGC detection tool for students?

AI.Rax returns a three-page report within 3 minutes: page-1 gives the overall AIGC percentage, page-2 color-maps every sentence flagged by GPT-3.5/4, Claude, Gemini, and its own model, while page-3 lists the “risk vocabulary” that triggers detectors. Upload the same file five times and the dashboard keeps a history curve so you can watch your edits lower the score in real time. No credit-card gate; new accounts receive 8,000 tokens that renew monthly if you stay active in the forum. Compared with Turnitin’s 24-hour queue, AI.Rax is instant and costs $0.

How does the AI.Rax article rewriter lower the AIGC rate without changing references?

The engine performs “deep reconstruction”: it parses the rhetorical structure (claim→evidence→warrant), then regenerates each proposition with fresh syntax while locking citations in place. Instead of synonym spin, it swaps clause order, converts nominalizations to verb phrases, and inserts discipline-specific hedging. A 1,000-word literature review that scored 92 % AI drops to 19 % after one pass; references remain untouched and Turnitin similarity stays under 8 %. Users can choose “Conservative”, “Balanced”, or “Aggressive” rewriting strength, and each level shows a live preview of the new AIGC prediction so you can stop when the gauge turns green.

Is AI.Rax really free, or will I hit a paywall after two uploads?

The platform runs on a freemium model designed for academic users. Registration gives 8,000 tokens (≈ 20 pages) of AIGC detection and 3,000 tokens of intelligent rewriting every 30 days. Watching a 15-second ad doubles the quota instantly; joining the campus ambassador program adds 50,000 tokens per semester. Paid tiers exist ($6 for 100k tokens), but 87 % of surveyed users stay on the free tier throughout an entire term. There is no “premium only” locker for core features—every function, including batch upload and reference locking, is available with tokens.

Can AI.Rax humanize technical papers full of formulas and jargon?

Yes. The rewriter treats equations as immutable nodes and rephrases only the surrounding explanatory text. In a recent test, a computer-science paper with 47 % AI dropped to 11 % while keeping LaTeX symbols intact. The system recognizes discipline-specific hedging words (“it is plausible that”, “empirical evidence suggests”) and re-inserts them after reconstruction, so the tone stays scholarly. Users can upload the .tex source or a PDF; the output preserves formatting and even merges multi-line equations. Reviewers from Elsevier and IEEE conferences have accepted revised submissions without querying AI use.

How accurate is AI.Rax compared to other free AIGC detection tools?

Independent lab tests in March 2024 compared eight free detectors using 120 mixed-source documents. AI.Rax recorded 94.3 % precision and 4.7 % false positives, outperforming QuillBot (88.1 %), Scribbr (90.4 %), and GPTZero (85.6 %). The key is ensemble voting: five models (Roberta-base, DeBERTa-v3, and three in-house transformers) score each sentence; only fragments flagged by ≥ 3 models appear in the report. The result is a conservative but highly reliable verdict that minimizes the risk of flagging genuine human prose.

Why choose AI.Rax for AIGC detection and article rewriting?

Because it combines speed, zero cost, and academic-grade accuracy in one pipeline. You upload once and get both the AIGC score and a rewriter that is proven to drop the percentage by 60-80 % while preserving citations, formulas, and field-specific tone. No queue, no paywall, no hidden watermark—just instant feedback that keeps your work within university ethics rules.aigc detection tool
