Copyleaks

Copyleaks is a content integrity platform that checks text for AI-generated writing, plagiarism, and copied code in a single scan. It is built for schools, publishers, and businesses that need to verify originality at scale. Its AI detector covers 30+ languages, while its plagiarism checker covers 100+ languages. A detector score is never proof on its own, so reviewers should check drafts and flagged passages before acting on any result.

Key Features

1. AI Content Detection

Detect AI-generated text across 30+ languages, with sentence-level highlights that show which parts of a document look machine-written.

2. Plagiarism Detection

Find matching content across billions of web pages and published sources, with source links shown next to each matched passage.

3. Code Plagiarism Detection

Check source code for copied work across programming languages, which helps teachers and teams review student and developer submissions.

4. Source Comparison

Compare two documents against each other to spot internal copying, such as one student paper reused from another submission.

5. Detailed Similarity Reports

Receive a full report with similarity scores, matched sources, and AI probability, so reviewers can inspect evidence instead of trusting one number.

6. API and Platform Integrations

Embed detection into your own tools through an API, or connect it to learning platforms such as Canvas and Moodle for assignment checking.

7. Paraphrase Detection

Spot rewritten or paraphrased passages, not just exact copies, because the system compares meaning as well as matching words.

Conclusion

Copyleaks suits schools, publishers, and teams that need AI and plagiarism checks in one place. Its wide language coverage, code checking, and platform integrations save review time.
