Frequently Asked Questions

Yes. The Copyleaks API can scan across multiple formats:

  • Plain text – Detects plagiarism and AI-generated content from plain text or file uploads.
  • Source code – Supports plagiarism detection for dozens of programming languages, including Python, Java, C++, and more.
  • Images (OCR) – Extracts text from images and checks it for duplication or similarity.

Our AI Detector identifies content generated by all major LLMs, including GPT‑4 (OpenAI), Claude (Anthropic), Gemini (Google), Llama (Meta), DeepSeek, and others. Detection is based on generative techniques rather than individual models, allowing us to adapt quickly as new models emerge.

The API is platform‑agnostic and can be integrated into any application. In addition, Copyleaks offers out‑of‑the‑box integrations with leading platforms, including:

  • Learning Management Systems (LMS) such as Canvas, Moodle, Blackboard, Brightspace, Schoology, Sakai, and Edsby.
  • Google Docs via our official add‑on.
  • Browser extensions for real‑time content checks.

No. Content submitted to the Copyleaks API is not stored, shared, or used to train public AI models. Customer data remains private and secure. We only process submissions to generate scan results and, if required, provide secure storage under customer agreements.

Rather than training against individual models, Copyleaks focuses on detecting the patterns and structures common to generative AI. This approach ensures immediate coverage of new LLMs as they’re released, with continuous updates to maintain high accuracy and low false‑positive rates.

We provide official SDKs and sample code for:

  • Python
  • Java
  • C# (.NET)
  • Node.js
  • PHP
  • Ruby

These SDKs simplify integration and speed up development across different environments.

The API uses Bearer token authentication. After generating an API token via your Copyleaks dashboard, include it in the Authorization:

Bearer <token> header for each request.

Integration is straightforward:

  1. Sign up for a Copyleaks account and obtain your API credentials.
  2. Choose your preferred SDK or call the REST endpoints directly.
  3. Submit content (text, files, or code) for scanning.
  4. Receive results via webhook callbacks or polling.
  5. Customize usage for your workflow—whether embedding in an LMS, internal tools, or custom applications.

Yes:

  • Plagiarism Checker API – Identifies duplicate content, paraphrasing, cross‑language matches, and code plagiarism.
  • AI Detector API – Flags AI‑generated content using AI Logic, providing detailed insights like AI Phrases and AI Source Match.
  • Grammar Checker API – Offers grammar, style, and tone suggestions to improve writing quality.

These APIs can be used individually or together, depending on your needs.
