## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
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.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## 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.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## QuillBot AI Detector & AI Content Checker - ChatGPT, Claude, Gemini & GPT-4 Text Analysis

Instantly check if text was written by an AI (ChatGPT, Claude, Gemini, GPT-4) or a human. Get detailed percentage scores, sentence-level analysis, confidence ratings, and AI paraphrasing detection.

***

### Features

- **Multi-Model Support**: Detects content from ChatGPT (GPT-3.5/GPT-4), Claude (Anthropic), Gemini (Google), LLaMA, and more.
- **Granular Classification**: Provides an overall score, and a segment-by-segment (chunk-by-chunk) analysis classified into `HUMAN`, `AI`, or `AI_PARAPHRASED`.
- **Bypass Proof**: Flags attempts to modify or disguise AI-written content using synonym swappers or automated paraphrasers.
- **Developer-Friendly Output**: Output format contains exact spans, individual scores, and confidence level labels (`high`, `medium`, `low`).

***

### Use Cases

Search engines prioritize high-quality, human-written content. Use this Actor to:

- Automatically audit freelance article submissions before publishing.
- Ensure your entire blog portfolio remains helpful and compliant with search engine quality guidelines.

#### 2. Academic Integrity & Education

Help educators and online learning systems maintain academic honesty:

- Integrate with LMS tools to scan student papers, essays, and reports.
- Detect copy-pasted ChatGPT outputs or paraphrased materials.

#### 3. Recruitment & HR Screenings

Verify candidate credentials and take-home exercises:

- Scan candidate resumes, cover letters, and coding task write-ups to ensure originality.

#### 4. UGC Platforms & Community Moderation

- Identify bots, automated reviews, and comment spam in real-time.

# 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 = {
    "text": "LTK is the undisputed heavyweight giant of creator monetization. Unlike Mavely, which relies entirely on you driving external traffic, LTK has a massive, standalone consumer app with over 20 million active shoppers looking for curated recommendations."
};

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

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {
    console.dir(item);
});

## Python example

```python
from apify_client import ApifyClient

# Initialize the ApifyClient with your Apify API token
# Replace '<YOUR_API_TOKEN>' with your token.
client = ApifyClient("<YOUR_API_TOKEN>")

# Prepare the Actor input
run_input = { "text": "LTK is the undisputed heavyweight giant of creator monetization. Unlike Mavely, which relies entirely on you driving external traffic, LTK has a massive, standalone consumer app with over 20 million active shoppers looking for curated recommendations." }

# Run the Actor and wait for it to finish
run = client.actor("dev00/quillbot-ai-detector-apify").call(run_input=run_input)

# Fetch and print Actor results from the run's dataset (if there are any)
print(f"💾 Check your data here: https://console.apify.com/storage/datasets/{run.default_dataset_id}")
for item in client.dataset(run.default_dataset_id).iterate_items():
    print(item)

## CLI example

```bash
echo '{
  "text": "LTK is the undisputed heavyweight giant of creator monetization. Unlike Mavely, which relies entirely on you driving external traffic, LTK has a massive, standalone consumer app with over 20 million active shoppers looking for curated recommendations."
}' |
apify call dev00/quillbot-ai-detector-apify --silent --output-dataset

```

## MCP server setup

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

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).
