## Overview

Plag is a web-based plagiarism checker and AI detector aimed squarely at academic writing. You upload a document, and rather than returning a single opaque percentage, it breaks the result into parts: an overall similarity score, a separate plagiarism risk indicator, the proportion of paraphrased material, the proportion of improper citations and the highest match from any single source. That structure is what makes the report actionable, because each category points to a different fix.

The interface reinforces this. Paraphrased passages are flagged in orange, improper references in purple and correctly formatted quotations in green, so a student can scan the document and understand which passages actually need work. Every flagged section carries a link to the matching source, which lets you confirm the overlap and correct the citation or rewrite the sentence with the original context in front of you. Plag presents itself as one of the few checkers that surfaces improper citations as a distinct category rather than lumping them in with outright copying.

The comparison base combines open web sources with a scholarly article collection of more than 80 million items from recognised academic publishers. Plag also advertises real-time search that can detect similarities with pages published as recently as roughly ten minutes earlier, which matters when students draw on fresh blog posts, news pieces or documentation. The tool supports 129 languages, matching its multilingual user base in Europe and beyond.

On the commercial side, Plag keeps a free entry point: an initial check with a similarity score, available before you commit to a paid report, and free educational use for teachers, lecturers and professors at schools and universities worldwide. Paid plans and document services such as editing, proofreading, formatting and plagiarism removal are available for students and institutions.

## Pricing & Plans

Freemium with a free initial check and free use for educators. Paid credit plans are listed in euros: a Basic tier around €14.95 per month for 10,000 credits, a Student tier around €29.95 per month for 30,000 credits and a PRO Unlimited tier around €299.95 per month, with plagiarism checks, AI detection and cross-language translation plagiarism billed at one credit per word. Annual billing advertises discounts, and editing, formatting and plagiarism-removal services are quoted per document.

## Key Features & Capabilities

- **Similarity and risk scoring:** Every submission gets a similarity percentage alongside separate indicators for paraphrased text, improper citations and the highest single-source match, so you see not just whether you scored high but why.
- **Colour-coded highlighting:** Matches are colour-coded: paraphrases in orange, improper citations in purple and correct quotations in green, which makes the editing pass far quicker than reading a raw match list.
- **Scholarly article database:** Beyond the open web, Plag compares files against a proprietary collection of more than 80 million academic articles gathered from recognised scholarly publishers.
- **Source links for every match:** Every highlighted passage is linked back to the source page it overlaps with, so you can verify a match, fix a citation or rewrite a sentence with the original context in view.
- **Multilingual and real-time detection:** The checker covers 129 languages and can spot overlaps with pages published only minutes earlier, keeping results current for fast-moving online sources.

## Primary Use Cases

- **Pre-submission self-check (Students):** Run a check before submitting a thesis or assignment to catch accidental copying, fix paraphrases and confirm that quotations are formatted correctly.
- **Educator screening (Teachers and professors):** Screen student papers and assignment drafts for originality and AI-generated text, with free access for educators at schools and universities.
- **Originality assurance (University and institutional staff):** Verify that papers, reports and grant applications meet originality expectations, then use the source links to correct citations before publication.
- **Document polishing services (Editors and proofreaders):** Add editing, proofreading, formatting or plagiarism-removal services when an author or department needs hands-on help beyond the automated report.

## Strengths

- Free use for teachers, lecturers and professors for educational purposes
- 80 million-plus academic article database alongside open web sources

## Limitations
