About

UnPlagiarize shows you which parts of a piece of writing already exist online, and links the actual sources so you can judge for yourself. When something needs work, it rewrites it while keeping quotes, citations, numbers and names intact, and shows you exactly what changed.

  • Source-backed checksMatched passages are highlighted and linked to the pages they came from. No opaque percentage.
  • Careful rewritesSix rewrite modes that preserve quotations, citations, figures and names, with a full diff.
  • Scan paperRead printed pages with on-device text recognition, or import PDF, TXT and Markdown files.
  • Account optionalStart without signing in on Android and iOS. Link Google, Apple or email so credits and Pro follow you to a new device and to the browser.
  • Documents stay localYour documents, reports and rewrites stay where you made them, on the phone or in the browser. Text goes to the server only when you run a cloud action such as a check or a rewrite.
  • Fair pricingFree actions every day, credit packs that never expire, or Pro for much higher limits, longer documents and no ads. Purchases are made in the Android and iOS apps.
