## 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

## 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
