## CatchGPT

CatchGPT is a browser-based AI content detector distributed as a Chrome extension. Its stated mission is to preserve the value of human-generated knowledge by making it easy to flag text and imagery that appears to have been produced by generative AI. Rather than pasting content into a separate web app, you install the extension and trigger a detection pass directly on the page you are reading.

In day-to-day use it works as a quick triage layer. A single click runs the detector against the current selection or page, returning a simple human-versus-AI signal that a writer, editor, teacher or reviewer can act on. Because it lives in the browser, it fits naturally into existing review workflows such as proofing drafts, moderating submissions or checking marketing copy before publishing.

The extension is published on the Chrome Web Store under the CatchGPT name and carries a small footprint. It is positioned as a free tool with a strong emphasis on distinguishing specialised human knowledge from generic AI-generated text, and it is aimed at anyone who needs a fast sanity check rather than a heavy compliance platform. Note that the separate domain catchgpt.ai now hosts an unrelated product aimed at teachers, so the extension remains the authoritative CatchGPT AI-detector product.

**Pricing & Plans:** Free to install from the Chrome Web Store; no paid tiers are advertised on the extension listing.

- **One-click detection:** Run an AI-content check on the page or text you are viewing with a single click, without leaving your tab.
- **Text and image coverage:** Flags both AI-written text and AI-generated images so you can evaluate mixed-media content in one pass.
- **Signal-versus-noise verdict:** Returns a straightforward human-versus-AI signal designed to be read at a glance rather than as a dense report.
- **Lightweight Chrome extension:** Installs in seconds from the Chrome Web Store and stays out of the way until you need it.
- **Human-knowledge focus:** Built around the goal of preserving the value of human-created content for writers and reviewers.

**Strengths:** One-click workflow keeps detection inside the browser tab you are already reading; Covers both text and images rather than text alone; Free to install with a very small download footprint; Simple human-versus-AI verdict that non-technical users can act on

**Limitations:** Very small user base and few reviews compared with mainstream detectors; Extension has not been updated since 2023, so detection accuracy may lag newer AI models; No detailed scoring, reporting or team features for compliance use cases

## 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.
