Copyleaks评论、价格、功能、优缺点

Are you struggling to know if content is truly original or generated by sophisticated AI models? This uncertainty erodes trust and complicates compliance. Copyleaks provides a powerful solution to this challenge.

It offers industry-leading accuracy to distinguish human writing from LLM outputs. You gain confidence and clarity immediately. ✨

Copyleaks 是什么？

Copyleaks is a robust platform focusing on digital authenticity. It uses advanced AI technology to analyze unique text patterns. This focus allows the system to flag content created by various Large Language Models (LLMs), including GPT-5, Gemini, Claude, and dozens more.

The tool helps you clearly identify AI writing because it looks for signals left behind by statistical modeling. You can also get detailed reports that separate elements written by humans from AI-generated text, even when both are mixed. The platform is truly built for accuracy and scalability.

✅

Copyleaks 主要功能

✨ Unrivaled Accuracy and Verified Trust

You can fully depend on the results delivered by our detection system. We use large-scale, credible data with machine learning to ensure high confidence. This results in over 99% detection accuracy across all document types.

We minimize errors to ensure your trust is warranted. The likelihood of mistakenly flagging accurate human text as AI is only 0.2%. This extremely low rate is among the most competitive in the industry. Independent studies, including research published by Cornell Tech, have validated our status as the most accurate LLM detector.

✨ Comprehensive AI and Code Detection

Our system identifies content created by virtually all sophisticated language models. When an LLM writes, it creates unique, statistical patterns that we recognize instantly. We successfully detect content from models like GPT-5, Gemini, Claude, Llama, and many others.

Copyleaks also provides advanced detection specifically for developers. The detector can analyze and identify AI-generated code. This identification works even if the code has been slightly altered after generation.

✨ Granular Reports for Mixed Content

When content is blended, our system separates the parts written by humans from the AI components. You receive detailed reports that identify specific elements within the text. This is crucial for verifying authenticity when human and machine inputs are mixed in one document.

We include an explainable AI Logic feature in all individual plans. This feature helps you understand exactly how the system arrived at its detection decision. It adds clarity and transparency to the scoring process.

✨ Smart Filtering for Editing Tools

Our detector smartly distinguishes between minor editing tools and generative rewriting features. We focus on finding true AI generation, not helpful corrections. Basic functions like standard spell check or grammar correction are not automatically flagged.

This prevents friction when you use common tools like Grammarly for basic cleanup. Detection is usually only triggered by features that actively rewrite or generate new content using AI assistance. We ensure a fair and accurate analysis of the content's origin.

✨ Industry-Leading Compliance and Security

Security and data privacy are our paramount concern. All Copyleaks products adhere to strict global security and compliance standards. Access to your sensitive data is protected against threats and misuse.

These are some of the key certifications and standards we meet:

  • SOC2 & SOC3
  • GDPR
  • PCI DSS

✨ Flexible Scanning and Integration

You can scan content using our web platform or browser extension. The web platform handles very large documents, supporting up to 2,000 pages for a single scan. The confidence of our detection improves when more text is provided.

  • Web Platform Minimum: 255 characters
  • Browser Extension Minimum: 350 characters

For large teams or institutions, we offer seamless scalability. This includes full API access and specialized LMS integration. We also provide AI detection across 30+ languages and plagiarism checks in over 100 languages.

使用案例

🎓 Ensuring Academic Integrity in Education

University administrators and instructors need reliable tools to uphold academic honesty. Copyleaks integrates directly with Learning Management Systems (LMS) using custom solutions. This integration allows institutions to securely scan massive volumes of student work, including essays and internal reports.

Students submitting papers through the LMS receive a dual check for both AI generation and traditional plagiarism in one comprehensive report. This streamlined process provides instructors with immediate clarity, helping them avoid false accusations and focus on genuine learning outcomes.

📝 Vetting High-Volume External Content

When a Marketing Director uses a large pool of freelance writers, they must quickly confirm originality to protect the brand’s integrity. They use the platform to vet dozens of articles that rely on LLMs like GPT-5 or Gemini. The system looks for the unique patterns left by statistical modeling before publishing.

Because Copyleaks features an extremely low false positive rate (0.2%), the risk of flagging genuine, human-written content is minimized. This allows the team to maintain high content quality, ensure digital trust, and operate under strong security standards (SOC 2/3) across all content streams.

💻 Verifying Code Composition in Development

Many software teams use generative AI tools to rapidly create code blocks. However, legal and security compliance requires knowing the true origin of all deployed components. Copyleaks can analyze and identify the specific signals left by AI-generated code, even after human developers alter it.

This verification process can be integrated directly into development workflows via the API. The detailed report confirms if the code is entirely human-written or contains components sourced from an LLM. This use case supports crucial compliance efforts by accurately tracking software lineage.

🔍 Analyzing Mixed Human and AI Documents

Often, a document is partly written by a person and partly refined or expanded using an AI tool. A policy analyst submitting a complex research draft needs to know exactly which portions came from the human author. Copyleaks provides detailed reports that separate elements written by humans from AI-generated text, even when both are heavily mixed.

This function, using the explainable AI Logic feature, highlights specific sentences or paragraphs created by a Large Language Model. This distinction helps supervisors assess contributor honesty and allows for highly targeted, accurate revisions based only on the AI-generated parts.

🌍 Maintaining Global Compliance and Security

A multinational firm generates content in dozens of languages and must adhere to strict international privacy mandates. Since Copyleaks is certified GDPR and SOC 2/3 compliant, the organization can confidently use it worldwide. The platform supports AI detection in 30+ languages, ensuring consistency.

This compliance focus eliminates the need for separate, regional scanning tools. It ensures that content accuracy checks across Spanish, Japanese, or German teams all meet the same enterprise-grade security protocols. You gain standardized, secure digital trust across your organization.

用户评论

Copyleaks reviews present a sharply divided user experience, reflected in its overall low Trustpilot score. The main criticism involves the tool's core function: accuracy.

Many users, including long-time professional writers, report frustrating experiences where clearly human-written content—even text drafted before LLMs existed—is flagged as 100% AI. These extremely high false-positive rates strongly undermine confidence in the tool’s reliability, causing users to call it a "fake AI detector." Furthermore, users highlight significant issues with the credit system and billing practices.

They describe the usage model as misleading, citing instances where they felt penalized by having to purchase additional credits due to initial, inaccurate scans or accidental re-scans of their stored documents. The pricing is sometimes viewed as expensive and the policies concerning refunds and account deactivation are reported to be difficult.

Customer support responsiveness is also frequently criticized, often resulting in automated responses and unresolved disputes. Despite marketing claims of unparalleled precision, the practical user experience frequently points to a flawed system with substantial usability challenges.

I have 35 years of writing experience, and when I put my journal entry into Copyleaks, it returned 100% AI content. Every other competing software says 100% Human. Copyleaks is an epic fail.

The credit system and billing are misleading. I was penalized for checking my own work twice because the system stored the first version. This unfair business model forced me to pay for credits twice for one job.
