Why Teachers Need a Plagiarism Checker

Unlike Turnitin or PlagScan, our tool works for individual educators with no IT setup or license fees.
EU-Hosted
All processing stays in EU infrastructure (europe-west1, Belgium). Important for teachers in EU institutions handling student data.
Evidence-Based Conversations
Use similarity readings as a starting point for conversations with students, not as the final word.
How to Use Our Teacher Plagiarism Checker
- Upload the student's submission in PDF or DOCX format, or paste the text.
- Our tool scans for overlap with common-knowledge sources and standard phrasing.
- You get the exact sentences we flagged - stock academic phrases and uncited quotations that inflate a similarity report. We do not compare against a database, so we never invent a percentage.
- Use the score as one data point alongside your professional judgment and institutional process.
- Check as many submissions as you need - no limits, no per-scan fees.
Tips for Educators
- Use plagiarism scoring as one data point, not the sole basis for academic-integrity decisions.
- Set clear citation expectations in your syllabus and reinforce them early in the term.
- Compare flagged work against the student's previous submissions for stylistic consistency.
- When confronting students, focus on specific flagged passages rather than general accusations.
- Pair plagiarism detection with AI detection for fuller coverage of academic-integrity concerns.
