## 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

## Scribbr

Scribbr was built around a simple promise: help students submit work they feel confident about. The core of the service is human proofreading and editing, delivered by a hand-picked pool of academic editors who go through an in-house training programme before they are allowed to take orders. Documents are returned with tracked changes, in-text comments and a short personal letter explaining the reasoning behind the main edits.

Alongside the human service, Scribbr offers a growing library of AI writing tools. The Academic Check bundles together grammar and language review, citation checking, plagiarism scanning and AI-content detection into a single upload, which is convenient when you want one pass over an entire paper rather than juggling separate tools. Individual utilities such as the citation generator for APA, MLA, Chicago, AMA, IEEE and ACS, the paraphrasing tool and the text summarizer can be used on their own without paying for an edit.

The platform also maintains a large free knowledge base of academic writing guides that has become one of the more popular ways students discover the brand. Pricing depends heavily on document length, chosen turnaround time and add-on checks, so the practical way to get a number is to upload a file and select services in the order flow.

**Pricing & Plans:** Freemium model. Free tools include the citation generator, grammar checker and summarizer. Human proofreading and editing, the plagiarism checker, AI detector, AI proofreader and Academic Check are paid per document, with the final price depending on page count, delivery speed and any add-on checks such as structure or clarity review.

- **Human proofreading and editing:** A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
- **Plagiarism checker:** Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
- **AI detector and AI humanizer:** Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
- **Citation generator:** Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
- **Academic Check bundle:** Runs grammar, citations, clarity, plagiarism and AI-detection checks in a single upload of the whole document.

**Strengths:** Combines human editors with AI tools rather than relying on one alone; Strong editorial vetting process and a large pool of academic specialists; Free citation generator and knowledge base are genuinely useful on their own; Transparent turnaround options starting from a few hours

**Limitations:** Paid services are priced per document, which adds up for long theses; AI detector verdicts can still be disputed by institutions; Some premium checks require you to buy them alongside an editing order
