## 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.

## Smodin

Smodin bundles the tasks that students, researchers, and content teams usually spread across several subscriptions into a single workspace. The headline trio is an AI content detector, an AI humanizer, and a plagiarism checker: paste or upload a draft and the detector returns an overall AI-probability score with sentence-level highlights, the humanizer rewrites text so it reads more naturally, and the plagiarism checker scans against a large source index to flag anything that needs a citation. An AI writer and chat assistant covers drafting, outlining, and brainstorming.

Alongside those, Smodin provides a longer list of supporting utilities — a rewriter and spinner, text summarizer, language translator with broad language support, paraphrasing, and an AI watermark remover — plus a Chrome extension for using the tools without leaving the browser tab where you are writing. The workflow is consistent across tools: enter text, choose the operation, review results, and iterate, and the site reports scanning speeds under a second and support for well over a hundred languages.

The platform is positioned primarily for students, academics, and professional writers, and it says text submitted for scanning is not stored or shared. Access is via paid subscription plans, with free trials and limited free usage available so you can test the detector, humanizer, and checker before committing to a plan.

**Pricing & Plans:** Paid subscription plans with free trial access and limited free usage on several tools; pricing tiers are listed on the Smodin pricing page and cover increasing word limits, tool access, and language support.

- **AI content detector:** Scan text for AI-generated patterns with sentence-level highlighting and a plain-language verdict covering writing from models like ChatGPT, Claude, and Gemini.
- **AI humanizer:** Rewrite AI-generated text so it reads naturally and more closely matches a human voice, useful before submitting essays, articles, or client work.
- **Plagiarism checker:** Check drafts against a broad index of sources to confirm originality and surface places that need proper citation.
- **AI writer and chat:** Draft, outline, and refine content with an AI writing copilot and chat assistant that handles academic and SEO-oriented briefs.
- **Rewriter, translator and extras:** Supporting tools round out the suite, including a rewriter and spinner, text summarizer, language translator, paraphrasing, AI watermark remover, and a Chrome extension.

**Strengths:** Detector, humanizer, plagiarism checker, and writing assistant combined in one workspace; Consistent paste-and-go workflow across every tool; Broad language support and a Chrome extension for in-browser use; Fast scans with a free trial path to test before paying
