Consecutive-word matching
Identifies matching word sequences in the manuscript and readable retrieved source texts. Longer phrases are prioritised and counted once.

Text-based PDF, DOCX or TXT · up to 12 MB · scanned PDFs require OCRi
Upload just one document. BRIHANTRA will search publicly indexed academic records and assess text that is legally and technically accessible.
Compare this sample with its original synthetic test fixtures locally. Nothing is sent to academic services. This is not a plagiarism report.
Private by design: the document stays in this browser. Only search keywords you approve are sent to third-party academic services, and a manuscript phrase is sent only with separate consent.
Automatic assessment
SINGLE DOCUMENTKnown published source — exact verification (optional)
For a positive-control manuscript, specify the PMCID of the actual published article. The app will attempt that article's open-access XML first, independently of keyword search rankings. It will not upload your manuscript or invent a match if the source is unavailable.
Selecting the article fills its identifier. You must still tick the consent box below to request that article, then run a new assessment.
Optional phrase-based source search

Word-range source discovery
The manuscript is divided into overlapping passages based on the selected word count. All accessible retrieved text is compared locally; only a small, visible sample of passages can be searched in external academic indexes.
Upload a manuscript to preview word-length passages.
Exclude common or standard phrases (optional)
Matching instances are excluded from the similarity numerator and the eligible-word denominator. These phrases are never sent to search providers.
Upload one manuscript to begin.
No manuscript selected.
Compare a reference PDF you already possess — local only
Use this when a legitimate open repository copy cannot be retrieved automatically (for example, HAL). The selected reference PDF stays in this browser, with no academic-provider search or PDF upload. This is a user-provided source, not an independently authenticated HAL or publisher copy. Cite and verify the reference yourself.
Upload a manuscript, then select a reference PDF for local comparison. Scanned PDFs require OCR.
Explore more academic sources (manual research links)
These sites can identify additional research, including Indian theses. Opening them is optional; their results are NOT automatically compared or included in the similarity percentage. Scopus and Web of Science may require subscriptions.
For Shodhganga, the link searches Google's index of that repository; it is not a Shodhganga API.

Interpretation matters: A similarity percentage is not a plagiarism verdict. Legitimate citations, shared terminology and standard phrases may match. The score reflects only the retrieved readable sources, never the entire web or publisher databases.

Each source percentage means the portion of this manuscript whose exact wording matches that source. A passage may appear in multiple sources, so individual percentages cannot be added. Exclude or restore sources to recalculate the overall result.

METHODOLOGY & LIMITS
Know what the score means.
BRIHANTRA Originality v2.6.1 reviews a single uploaded manuscript against selected accessible academic source text. It is not an internet-wide plagiarism screening system or a plagiarism adjudicator. Supported public repository PDFs may be retrieved through a restricted, first-party open-access route; only user-approved passage samples are searched in the scholarly index.
Conservative close matching
Compares word overlap and three-word patterns to flag passages with minor wording changes. It cannot reliably identify conceptual copying or substantial paraphrasing.
Document-based score
Matched, eligible target words ÷ all eligible target words. Reference-list and quotation exclusions alter the denominator. It is not a Turnitin or iThenticate equivalent.
Privacy and supported files
Text is processed in your browser, without transmitting manuscripts to our server. Text-based PDFs need a PDF parsing library loaded online; scanned PDFs with no text layer require OCR and are not supported.
Questions researchers ask
Does it compare against Google or journal archives?
The app searches public OpenAlex, Crossref, and Europe PMC records after consent. It compares accessible abstracts and eligible Europe PMC open-access article-body text. It does not access the entire web, paywalled publisher full texts, or institutional plagiarism databases.
Can it detect AI-generated writing?
No. AI text detection is not included in this release, and such estimates can be unreliable.
Why might a PDF appear empty?
Some PDFs are scanned page images with no selectable text. Use an OCR tool to create a searchable PDF or convert its text into DOCX/TXT before uploading.
Are the results accepted by universities?
No institutional acceptance or equivalence to official similarity-check platforms is claimed. Use this for preliminary self-review; follow your institution’s policies for official submissions.
