PlagiarismSearch

PlagiarismSearch puts a full plagiarism and AI-detection workflow on your phone. Paste a text, pick a file, or share a document into the app — and get back a report with a similarity percentage, every matched passage highlighted, and a link to the source it came from.

WHAT YOU CAN CHECK • Text you paste or type directly into the app • Documents in popular formats, including PDF, DOC, DOCX, TXT, and RTF • Files shared into PlagiarismSearch from Files, Mail or any other app • Documents you already keep in your personal storage

WHERE WE LOOK • The open web • Academic databases built on over 500 million indexed academic texts • Your own storage, so a new draft can be compared against your earlier work • AI-writing analysis that estimates how likely a text was machine-generated, for the whole document and passage by passage

REPORTS THAT EXPLAIN THEMSELVES • Overall similarity percentage and total AI rate • Matched passages highlighted and linked to the sources they match • Complete source list showing what each source contributed • Export a report to PDF or send a report link to a colleague or student • Reports you have already opened stay readable when you lose connection

TUNE THE CHECK TO YOUR RULES • Leave quotations and reference lists out of the score • Normalise look-alike characters used to disguise copied text • Whitelist or exclude specific domains and pages • Save your preferred settings once and reuse them for every check

YOUR DOCUMENT LIBRARY Keep checked documents in folders, reuse them as comparison sources, and find any past report by keyword or by date.

TRUSTED BY MORE THAN 500,000 CLIENTS Students check drafts before submitting them. Teachers and editors review what they receive. Researchers keep their citations clean. Most checks finish in about a minute; long documents can take a few minutes more.

ACCOUNT AND PAYMENT Sign in with Apple, with Google, or with an email address. Checks are paid for with word packages or with a subscription bought inside the app.
