Research with care. Write with confidence.

A bounded three-word-overlap review flags some similar sentences with wording differences in the sources actually compared. Candidate passages are shown beside their source excerpt and remain separate from the exact-match percentage. This lexical heuristic does not establish semantic equivalence or detect every paraphrase or translation.

AI Ink compares text with supplied sources, an account-private source index and optional retrieved web results. Reports include matching passages, citation-format checks, reference-list issues and explainable writing patterns. Similarity requires context and does not establish plagiarism by itself.

AI Ink imports searchable PDFs and DOCX files up to 10 MB. Extracted submissions need 200–120,000 characters. Scanned PDFs need OCR first, and older .doc files are unsupported. The preview shows extracted text rather than the original page layout.

You can add a chapter passage that you have permission to use as a private comparison source. Each indexed source supports 200–60,000 characters and at most 12,000 words. AI Ink does not automatically access copyrighted books or paywalled publisher collections.

AI Ink stores eight-word source fingerprints with your account. A scan retrieves candidate sources and confirms contiguous matching text before reporting evidence. Reports show indexed, candidate and compared counts. The index currently supports twenty private sources, with up to ten candidates compared per scan budget.

AI Ink does not automatically add submissions to a shared student repository. Private reports belong to their account. Sources enter the private index only through the source-index tool. Removing a source does not remove excerpts already saved in an older report.

Report filters can exclude recognized bibliography sections, paired quotations, selected sources and short matching runs. Filters recalculate the visible similarity while retaining the original report evidence. Unclosed quotation marks do not cause the remainder of a paper to be excluded.

No. A low score only describes matching text in the sources actually compared. Missing sources, inaccessible books and paraphrased ideas can remain undetected. A high score can also include legitimate quotations. Read the evidence and apply your institution’s academic-integrity policy.

AI Ink links supported numbered and author–year citations to recognized reference-list entries. It flags unresolved citations, duplicate reference entries and references with no linked supported citation. These are review prompts; unusual citation styles and complex layouts can require manual checking.

With your opt-in, AI Ink sends up to eight DOI identifiers to Crossref and displays returned bibliographic metadata. A found record confirms a registry match, not the accuracy of your argument. An unavailable service or missing record is not proof of a fabricated reference.

Scopus verification requires a configured Elsevier API key and approved commercial access. Without that integration, reports explicitly show Scopus as not configured. Crossref DOI metadata is not Scopus indexing, a journal-quality rating, or permission to access publisher full text.

AI Ink’s current writing measurements describe phrasing, repetition and rhythm. They are not calibrated probabilities of AI authorship. AI Ink does not certify that a paper is human-written and does not promise to bypass another system’s detector or academic-integrity review.

No. AI Ink is an independent Syaahii tool and is not affiliated with Turnitin. Turnitin’s licensed publications and submitted-paper repository are not available through this implementation. AI Ink reports its own comparison sources and limits rather than claiming equivalent database coverage.

A finding can open its specific passage in the editing desk. Choose a writing mode, compare original and revised text, and explicitly accept the edit. Preserve attribution when paraphrasing, and verify facts and meaning before using any AI-generated revision.

A verified student account with a recorded purchased student pack or active paid subscription can use AI Ink. Free signup and referral wallet credits do not unlock this paid feature. Current student prices and payment terms are listed on the plans page.

No. AI Ink’s public page provides accessible product facts, canonical metadata, structured answers and a sitemap entry. Search engines and answer engines independently choose what to crawl, index and cite. These improvements make the product easier to understand without guaranteeing a ranking.
