Plagiarism detection that understands how writing is made

We combine document revision history with web similarity analysis to distinguish authentic drafting from copy-paste, paraphrasing, and transcription—so teachers get clarity and students build confidence.

Web similarity

Find likely sources across the web and surface side-by-side matches with links.

Paraphrase & transcription

Spot near-matches, lifted structures, and dictation/transcription patterns.

Revision-aware

Edits, timing, and drafting flow help confirm authentic effort versus pasted chunks.

Plagiarism report preview

Clear, actionable reports

See matched passages highlighted in context, with links to likely sources, paraphrase indicators, and revision-history cues. Confidence ranges and rationales keep conversations fair and constructive.

  • Side-by-side excerpts and percent-match summaries
  • Paraphrase/transcription flags with structural cues
  • Revision timeline overlays for paste events

How our detection works

Multi-signal analysis that respects learning, backed by transparent evidence.

Step 01
Setup

Ingest with scope

Teachers enable checks per class/assignment. Access is scoped and logged.

Step 02
Evidence

Revision-history signals

We read edit timelines, paste events, and cadence to differentiate drafting vs. sudden insertions.

Step 03
Similarity

Web & source matching

Similarity checks surface likely sources with overlap percentages and side-by-side excerpts.

Step 04
Paraphrase

Paraphrase & structure

We detect lifted syntax and meaning-preserving rewrites, even when exact words change.

Step 05
Behavior

Transcription cues

Timing and input patterns help differentiate original typing from dictated or pasted content.

Step 06
Review

Explainable report

Highlighting, rationales, and confidence ranges make it easy to review, discuss, and resolve.

Fair to students

Evidence emphasizes how work evolved, not just final text. That means fewer false alarms and clearer coaching moments.

  • Revision-aware scoring of risk
  • Readable explanations instead of red flags
  • Supports instruction on citation & synthesis

Useful for teachers

Drill into exact overlaps, linked sources, and paste events. Override with notes and keep the audit trail.

  • Side-by-side source comparisons
  • Confidence ranges & rationales
  • Class and school-level trends
