## Copyleaks

Copyleaks has focused on content integrity since 2015, starting with plagiarism detection and expanding into AI detection and governance as generative models spread. Its core AI Detector analyzes text across more than 30 languages and can identify output from leading models such as ChatGPT, Gemini, Claude and DeepSeek, while its Plagiarism Checker searches a database covering 60 trillion websites, 16,000+ open-access journals and millions of internal documents to catch copying, paraphrasing and character manipulation. A unified multi-modal layer adds detection for video, audio and images, aiming to replace fragmented single-purpose tools.

For organizations, Copyleaks goes beyond individual checks with a scalable API that plugs content analysis into existing workflows, LMS platforms and publishing pipelines. Its compliance and governance use cases map to academic integrity, generative AI governance, code governance, IP and copyright protection, and detection of unauthorized LLM usage. Reporting dashboards, integrations and role-based controls help teams act on results at scale.

Founded as a plagiarism tool, Copyleaks now serves both individuals and large institutions. Free web tools give students and writers quick access to the AI Detector and Plagiarism Checker, while paid enterprise plans provide higher volumes, richer reporting and dedicated support. The company reports 100+ countries, 500+ enterprise and education customers and tens of millions of monthly scans.

## Originality.ai

Originality.ai was built for the era in which a meaningful share of published text is machine-generated. Its core AI Checker classifies text as AI, human or mixed and highlights the individual sentences driving the verdict, while the same scan can also surface plagiarism matches, readability grades, grammar issues and shaky factual claims. Publishers, SEO teams, agencies and educators use it to vet freelancer drafts, student submissions and high-volume content pipelines before anything goes live.

The platform scales from a free trial scan up to enterprise workflows. A bulk scanner handles many documents at once, while the API and MCP integration let developers embed detection directly into their own tools. A Chrome extension runs checks inside Google Docs and the web, and a Writing Replay feature records the typing process so authors can demonstrate authorship. Team management, shareable reports, PDF exports and configurable scan history round out the publishing workflow.

**Pricing & Plans:** Free tier with a one-time 10K-word (100 credit) allowance and no subscription. Pro is about $14.95/month monthly or $12.95/month billed yearly for 200K words per month, and Enterprise is about $179/month monthly or $136.58/month yearly for 1.5M words per month. Additional credits can be purchased; 1 credit equals 100 words.

- **AI detection with sentence highlights:** Classifies text as AI, original or mixed and pinpoints which sentences most influenced the score, so reviewers know exactly where to look.
- **Plagiarism and content-quality checks in one pass:** Runs plagiarism matching, readability scoring, grammar and spelling fixes, guideline checks and fact/hallucination screening from the same scan.
- **Bulk scan, files and full-site scanning:** Upload DOCX, PDF or DOC files, paste text, scan a URL, or queue large batches of documents to process at scale.
- **Extensions, API and MCP integration:** Check content inside Chrome and Google Docs, or wire detection into your own apps through the REST API and MCP server.
- **Writing Replay and shareable reports:** Replay how a document was typed, tag scans, and export shareable links or PDF reports for teammates, clients or review boards.

**Strengths:** Single scan returns AI, plagiarism, readability, grammar and fact checks together; Sentence-level highlights and Writing Replay make results easy to defend; Bulk scan, API, extensions and team roles suit agencies and enterprises; Free trial credits let you test accuracy before paying

**Limitations:** Credit-based pricing can add up for very high-volume publishing; AI detectors can never be 100% certain, so results should be treated as signals rather than proof
