About SafeAssign.net
We built SafeAssign.net to close one gap that Blackboard never closed: letting students see their similarity score before they submit. No account required, no data stored, no guessing.
Why We Built SafeAssign.net
Every year, students submit assignments through Blackboard without any way to preview their SafeAssign similarity score. The official tool only runs after submission — at which point the report is already in the instructor’s hands. Students who inadvertently over-quote, recycle prior work, or leave citation formatting issues unresolved only discover the problem when it’s too late to fix it.
SafeAssign.net is an independent similarity simulator built to fill that gap. Paste your paper, receive an estimated Originality Report in under 15 seconds, and use the results to revise before your final submission to Blackboard. We are not affiliated with Blackboard or Anthology Inc. — we are a standalone tool built for students who want to submit with confidence.
Three Things We Do Differently
Similarity Score Simulation
Our tool runs your text through the same comparison logic SafeAssign uses — Internet sources, the ProQuest academic database, and institutional archive matching — and returns an estimated similarity percentage before you submit to Blackboard.
Originality Report Preview
You don’t just get a number. Every check produces a highlighted version of your paper showing which sentences triggered a match, along with a source breakdown by database — formatted the same way your instructor sees it in Blackboard.
Zero Data Retention
Your paper text is processed in memory and discarded immediately after your report is generated. We do not store, index, or share what you paste. Your work is never added to any database — it stays yours.
Built for Students, Not Institutions
SafeAssign.net is a student-facing tool. We are not designed for academic integrity officers, instructors, or institutions — we are designed for the person sitting in front of a draft, trying to submit clean.
Undergraduates
Navigating SafeAssign for the first time, unsure what a 22% similarity score actually means for their grade. We show you what’s flagged and why — so you can fix it before your professor sees it.
Graduate Students
Working with dense literature reviews, extensive citations, and prior published work. Our report helps distinguish citation noise from genuine similarity flags — so you submit only what needs revision.
International Students
Writing in a second language and relying on quoted sources more heavily than native speakers. We help identify which passages are flagged so you can decide whether to paraphrase or add a citation.
How It Works — Honestly
We believe students deserve a clear picture of what this tool is and what it isn’t. Before you use our free plagiarism checker, here are four things you should know.
- This is a simulator, not official SafeAssign. SafeAssign.net is an independent tool. It uses the same comparison methodology as Blackboard’s SafeAssign, but results may differ from the official report your institution generates. Treat our score as an informed estimate, not a guaranteed outcome.
- Your text is never stored. We process your submission in memory only. The moment your report is generated, the text is discarded. We do not log, index, or retain any paper content submitted through this tool.
- Results are an estimate, not a guarantee. Our similarity score is calculated using the same logic as SafeAssign, but our database coverage and weighting may produce a different number than the official Blackboard report. Use our results to identify and fix flagged sections — not as a final answer.
- We are not Blackboard or Anthology Inc. SafeAssign.net has no affiliation with Blackboard, Anthology Inc., or any educational institution. “SafeAssign” is a product of Anthology Inc. We use the name to describe the check our tool simulates — not to imply endorsement or partnership.
