Free plagiarism checker powered by AI

Unlike a basic plagiarism checker that only looks for verbatim copying, DocsSmart combines real-time web search with semantic similarity. That means it catches not just word-for-word matches, but also paraphrases and reworded ideas — the kind of plagiarism that most often slips past simple tools in theses, dissertations, papers and essays.

You upload the document as PDF or DOCX, the AI recognizes it as academic work, extracts the structure (title, author, abstract, sections) and runs the check over the full content. In minutes you get the originality score, the flagged passages and a list of sources with the exact link for each match.

For the student, it's the way to check for plagiarism before submitting and fix citations with confidence. For the advisor, it's a clear report to review the originality of the work. For the institution, comparison against the internal library detects overlaps between the organization's own works — something generic online checkers can't do.

Quick checks are included in the free plan; the full check, with broader web search, uses pay-as-you-go credits. Your files stay isolated per organization, and the web check runs in an ephemeral service that does not retain your content.
