## 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

## ZeroGPT

ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation.

Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%.

Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app.

**Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations.

- **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
- **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
- **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
- **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
- **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale.

**Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper

**Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language
