## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.
Actors are written with capital "A".

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
The best way to integrate Actors is as follows.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

# README

## ZeroGPT AI Text Detector & GPT Checker

High-accuracy AI text detection powered by ZeroGPT. Detects ChatGPT (GPT-3.5, GPT-4, GPT-4o), Claude 3, Google Gemini, Meta LLaMA 3, Mistral, and AI-generated text with sentence-level breakdown, word counts, and language classification.

***

### 🚀 Key Features

- **Multi-Model AI Detection**: Accurately detects content generated by OpenAI ChatGPT (GPT-3.5/GPT-4), GPT-4o, Claude 3 (Haiku, Sonnet, Opus), Google Gemini, Meta LLaMA 3, and QuillBot paraphrased text.
- **Sentence-Level Highlights**: Identifies exact sentences generated by AI (`ai_sentences`) versus human-written text (`human_sentences`).
- **Comprehensive Metrics**: Provides continuous percentage scores (`ai_percentage`, `human_percentage`), word counts (`ai_words`, `total_words`), `verdict`, and `language` classification.
- **High Speed & Enterprise Reliability**: Powered by a distributed edge architecture for zero IP blocking, fast turnaround (<1s per check), and 100% unique request fingerprinting.

***

### 🎯 What People Use It For

- **EdTech & Academic Integrity**: Audit student essays, homework submissions, and research papers for undisclosed AI assistance.
- **Publishing & Content Marketing**: Verify blog posts, SEO articles, press releases, and copy submitted by freelance writers.
- **Trust & Safety / UGC Moderation**: Screen user forum posts, reviews, and community submissions to prevent automated AI spam.
- **Hiring & Talent Acquisition**: Audit candidate resumes, cover letters, and assessment responses for AI generation.

***

### 📌 Decision Rule & Usage Recommendation

Check if `is_ai_generated === true` OR `ai_percentage >= 50.0`. If matched, flag the text submission for manual review or restrict synthetic text content automatically.

***

### 💡 What Problem Does This Solve?

- *"Receiving generic ChatGPT-generated articles and spam from content freelancers."*
- *"Manual checking of academic essays and job application letters is slow and inconsistent."*
- *"Lack of sentence-by-sentence evidence to prove AI generation to clients or students."*

ZeroGPT AI Text Detector delivers automated, low-latency synthetic text verification in a single API or Actor run.

***

### 🔍 Queries This Actor Answers

- *Is this essay written by ChatGPT, GPT-4o, or a human?*
- *Which exact sentences in this text were generated by AI?*
- *What is an accurate, low-cost Apify alternative to Originality.ai, Turnitin, and Winston AI?*
- *How do I detect AI text programmatically in Apify Actors, Python, or Node.js?*

***

### 📥 Input JSON Schema

Pass the text content you wish to analyze in the `input_text` field:

```json
{
  "input_text": "Artificial intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions. The term may also be applied to any machine that exhibits traits associated with a human mind such as learning and problem-solving."
}
```

***

### 📤 Dataset Output Format

Each run outputs a clean structured item to the default dataset and key-value store (`OUTPUT`):

```json
{
  "success": true,
  "is_ai_generated": true,
  "ai_percentage": 100.0,
  "human_percentage": 0.0,
  "total_words": 45,
  "ai_words": 45,
  "verdict": "Your Text is AI/GPT Generated",
  "ai_sentences": [
    "Artificial intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions."
  ],
  "human_sentences": [],
  "special_indexes": [],
  "language": "en",
  "additional_feedback": "",
  "details": {
    "textWords": 45,
    "aiWords": 45,
    "fakePercentage": 100.0,
    "isHuman": 0.0,
    "feedback": "Your Text is AI/GPT Generated",
    "detected_language": "en"
  }
}
```

***

### ⚠️ Failure Context & Error Handling

If an empty text string or missing parameter is provided:

```json
{
  "success": false,
  "error": "Missing required parameter: 'input_text' string cannot be empty."
}
```

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {
    "input_text": "Artificial intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions. The term may also be applied to any machine that exhibits traits associated with a human mind such as learning and problem-solving."
};

// Run the Actor and wait for it to finish
const run = await client.actor("dev00/zerogpt-ai-text-detector").call(input);

// Fetch and print Actor results from the run's dataset (if any)

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,dev00/zerogpt-ai-text-detector"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
