Frequently Asked Verification Questions
help_outline Will scanning my paper here flag Turnitin later?
No. SmrAI operates under a strict "ghost-read" protocol. Scanned text is never cataloged into Turnitin’s Global Reference Database or public web crawlers. When submitted to your institution, it will be evaluated cleanly.
help_outline How does the Auto-Citation Assistant format sources?
Our neural parser cross-references the matching passage’s DOI against CrossRef and PubMed metadata to retrieve exact volume, issue, author list, and year, structuring citation strings strictly according to official APA 7th, MLA 9th, and Chicago style manuals.
help_outline Can it recognize translated plagiarism?
Yes. SmrAI utilizes multilingual sentence transformers that represent conceptual meaning in shared high-dimensional vector embeddings, identifying matches even when an author translated a foreign paper into English.
help_outline What file formats and batch limits apply?
Pro Unlimited members can upload simultaneous ZIP or multi-file batches of PDF, DOCX, LaTeX (.tex), and TXT formats up to 100,000 words per single scan with zero page throttling.
help_outline How does SmrAI compare to DupliChecker and Copyleaks?
Unlike DupliChecker which enforces restrictive 1,000-word free limits and displays ad clutter, SmrAI offers high-speed deep academic scanning with cross-lingual matching across 82 languages, automated APA/MLA citation generation, and integrated Turnitin-safe humanization.
