PRUUVA VS. COPYLEAKS

Copyleaks detects AI text. Pruuva verifies what students understand.

Copyleaks is a strong institutional-grade detection platform with broad LMS integrations and multi-language support. But even with 30+ languages and source code scanning, it still answers the same narrow question every detector asks: "Was this written by AI?" Pruuva asks a better one: "Does this student understand the work they submitted?"

COPYLEAKS'S APPROACH

Statistical pattern detection at scale

  • Analyzes text for statistical patterns associated with AI-generated content across 30+ languages.
  • Integrates directly with Canvas, Moodle, Blackboard, Google Classroom, and Brightspace for institutional workflows.
  • Claims 99% accuracy with a 0.2% false positive rate — though independent benchmarks tell a different story.
  • Outputs a probability score indicating how likely the text is AI-generated, not evidence of understanding.
  • Also detects AI-generated source code, expanding beyond essays into programming assignments.

PRUUVA'S APPROACH

Comprehension verification, not text analysis

  • Generates adaptive follow-up questions based on the specific claims and reasoning in a student's submission.
  • Measures whether the student can explain, extend, and defend the ideas in their own work.
  • Produces a verified comprehension profile — not a probability score that invites disputes.
  • Works regardless of how the text was produced, because authorship is not the point — understanding is.
  • Gives educators evidence they can stand behind in conversations with students and parents.

Side by side

Copyleaks
Pruuva
Approach
Statistical text analysis to classify content as human or AI-written.
Adaptive comprehension interviews that verify understanding of submitted work.
What it measures
Probability that text was generated by an AI model.
Whether the student can explain and defend the ideas in their submission.
False positives
Claims 0.2%, but independent testing shows significantly higher rates, especially for non-native English writers.
Not applicable — there is no binary AI/human classification to get wrong.
Student experience
Students are scanned silently. A flag means suspicion with little recourse beyond appeals.
Students engage in a brief follow-up that lets them demonstrate genuine understanding.
Output
A percentage score estimating AI likelihood, sometimes with sentence-level highlighting.
A comprehension profile showing which concepts the student can and cannot explain.
Pricing model
Credit-based: 1 credit per 250 words. Costs scale with document length and volume.
Per-student pricing designed for institutional budgets. No per-word metering.

THE BOTTOM LINE

Copyleaks is a capable detection platform with strong LMS reach. But detection still asks the wrong question. Pruuva does not guess who wrote the text — it verifies who understands it.
