Copyleaks Pricing 2026
View SourceNew users receive limited free credits to scan up to 25,000 characters without logging in, enough to evaluate detection quality on sample documents. Most individual educators will want the Personal tier at $13.99/month billed annually, which provides 100 credits covering up to 25,000 words monthly with full AI Logic explanations and LMS integration. Small teams and departments should consider Pro at $74.99/month billed annually for 1,000 credits covering 250,000 words and advanced filters for institutional workflows. The credit system where one credit equals 250 words makes cost prediction challenging as usage scales, and many reviewers note it becomes expensive compared to flat-rate competitors. Education and Enterprise tiers require custom quotes based on student enrollment or organizational size, but unlock institution-wide analytics, dedicated cloud hosting, and compliance features that procurement teams require.

This dual-purpose platform scans student submissions, corporate content, and published articles against 60 trillion web pages, 16,000+ academic journals, and 20+ code repositories while simultaneously analyzing text for AI generation patterns from ChatGPT, Claude, Gemini, and every other major language model. It operates across Canvas, Moodle, Blackboard, and five other learning management systems, plus offers browser extensions and API access for custom workflows. What distinguishes it from competitors is the AI Logic feature, which highlights specific phrases that exhibit statistical AI patterns and identifies overlap with known AI-generated content, giving educators evidence rather than just suspicion.
What It's Like Day-to-Day

Copyleaks: Frequently Asked Questions (FAQs)
How does AI detection work?
AI detectors recognize statistical patterns left behind by Large Language Models. When an LLM writes a sentence, it uses pre-training data to create responses based on statistical modeling. Copyleaks is trained on human-written content samples, so AI-generated text becomes clearly distinguishable from human writing patterns.
What AI models can Copyleaks detect?
Copyleaks detects content from GPT-5, GPT-4, ChatGPT, Claude, Gemini, DeepSeek, Llama (Meta), Bloom, Rytr, Jasper, and more. Detection is based on generative techniques rather than individual models, allowing adaptation as new models emerge.
Does Copyleaks offer a free AI detector?
Yes, every new user receives limited free credits to explore AI and plagiarism detection tools. You can scan up to 25,000 characters without logging in. Personal and Pro plans include full access to AI detection, plagiarism checks, detailed reports, and AI Logic feature.
How accurate is Copyleaks AI Detector?
Copyleaks has over 99% accuracy with an industry-low 0.03% false positive rate. According to Cornell University (July 2023), Copyleaks is the most accurate AI detector for detecting LLM-generated text. Multiple independent studies have validated its accuracy and efficiency.
