What is aigc detection free and how does AI.Rax deliver it?
AI.Rax gives every new account 5,000 characters of aigc detection free credit—no credit card, no subscription. Upload your thesis, essay, or report in .docx or .pdf; within two minutes you receive a color-coded report that pinpoints GPT-style sentences, shows the overall AIGC rate, and lists confidence scores per paragraph. The engine cross-validates three in-house LLMs trained on 20 M academic papers, so false positives stay below 3 %. If you need more volume, daily check-ins add another 2,000 characters, keeping the service permanently free for light users.
| Plan | Free Quota | Extra Cost |
|---|---|---|
| Starter | 5 k chars | $0 |
| Plus | 50 k chars | $4.9 |
How accurate is aigc detection online compared to desktop software?
Cloud-based aigc detection online beats desktop tools on two fronts: model freshness and corpus breadth. AI.Rax refreshes its detection base every 48 hours with newly published journals and arXiv preprints, while offline packages update quarterly. In a 2024 benchmark covering 120 mixed-human-AI papers, AI.Rax reached 96.4 % F1-score versus 88 % for the leading offline suite. Online mode also means you avoid GPU setup and 3 GB downloads; a mid-range Chromebook can handle it. Encryption uses TLS 1.3 plus AES-256 server-side, so journal editors increasingly accept AI.Rax PDF reports without extra anonymization.
Can I paraphrase online with AI.Rax to lower both AI and plagiarism scores?
Yes. Click “Smart Paraphrase” right below the detection report; the same file is fed into a semantic rewriting engine that reconstructs sentence syntax instead of swapping synonyms. A 300-word Discussion section that originally scored 72 % AIGC and 18 % similarity dropped to 14 % AIGC and 4 % similarity after one pass. The built-in academic polishing layer simultaneously converts informal phrases like “a lot of studies” into “a substantial body of research,” meeting APA/MLA tone requirements. You can choose conservative, moderate, or creative rewriting strength; each option shows live word-count and readability (FK score) so you stay within journal limits.
| Strength | AIGC Drop | Similarity Drop | Readability Change |
|---|---|---|---|
| Conservative | –40 % | –7 % | +0.3 grade |
| Creative | –70 % | –15 % | +1.1 grade |
Is free paraphrase online secure for unpublished research?
Security is baked into AI.Rax’s “paraphrase online” pipeline: files are split into 256-bit encrypted chunks, processed in volatile RAM disks, then auto-purged after 24 hours. The platform is GDPR compliant and undergoes quarterly penetration tests by Cure53. For extra peace of mind, you can toggle “No-Store Mode,” which deletes the document as soon as the browser download finishes. Over 60 universities, including TU Munich and NUS, have added AI.Rax to their whitelist, confirming that unpublished data stays confidential. You retain full copyright; the terms of service explicitly state that no text is used to retrain external models.
How do free aigc detection and paraphrase tools handle citations and equations?
AI.Rax preserves every citation marker ([1], Author, Year) and LaTeX equation during both detection and paraphrase passes. The engine masks bibliographies and math blocks before analysis, so your original references are never rewritten. In tests on 50 IEEE conference papers, citation accuracy remained 100 % and equation integrity was untouched. After rewriting, you get a second report comparing the new manuscript against Crossref and Turnitin, ensuring that matched references do not inflate similarity. If you need APA 7th or Vancouver style tweaks, toggle “Citation Polisher” and the system will harmonize punctuation without altering paraphrased content.
