## Pricing

Pay per event

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.
Since this Actor supports Apify Store discounts, the price gets lower the higher subscription plan you have.

## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.

In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md):

```bash
pip install apify-client
```

In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md):

````bash
# MacOS / Linux
curl -fsSL https://apify.com/install-cli.sh | bash
# Windows
irm https://apify.com/install-cli.ps1 | iex
```bash

In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md).

If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md).

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

# README

## AI Training Data Collector — Clean Web Datasets for LLMs

Crawl websites and extract structured, clean text datasets perfect for fine-tuning LLMs and RAG pipelines. Removes boilerplate, deduplicates content, and scores quality automatically.

### What it does

1. **Cleans HTML content** — strips nav, headers, footers, ads, scripts, cookies, comments, and sidebars automatically
2. **Finds the main content** — intelligently targets `article`, `main`, `[role="main"]`, `.content`, `.post-content`, `.entry-content`, `#content` before falling back to `body`
3. **Converts to structured formats** — markdown, plain text, or JSON output
4. **Scores content quality** — 0-100 score based on length, word diversity, sentence structure, and document formatting
5. **Deduplicates pages** — skips duplicate content using MD5 hashing of the first 2,000 characters
6. **Crawls to configurable depth** — follows same-origin internal links up to 3 levels deep

---

### Input

| Field | Type | Default | Description |
|-------|------|---------|-------------|
| `urls` | array | `[Wikipedia AI]` | Starting URLs to crawl |
| `crawlDepth` | integer | `1` | Link depth to follow (0-3). `0` = only start URLs |
| `maxPages` | integer | `5` | Maximum pages to process per run (1-1000) |
| `outputFormat` | string | `markdown` | `markdown`, `plainText`, or `json` |
| `excludePatterns` | array | `[/tag/, /category/]` | URL path patterns to skip |
| `minWordCount` | integer | `100` | Skip pages below this word count threshold |

---

### Output

#### Dataset Schema

| Field | Type | Description |
|-------|------|-------------|
| `url` | string | Source URL |
| `title` | string | Page title or first H1 |
| `cleanText` | string | Extracted clean content (markdown/plain text) |
| `structuredContent` | object | `{title, body}` — only when `outputFormat: json` |
| `wordCount` | integer | Total words extracted |
| `qualityScore` | integer | 0-100 quality score |
| `sourceDomain` | string | Domain name (www stripped) |
| `language` | string | `en` or `unknown` |
| `crawlDepth` | integer | Depth level where page was found |

#### Output Example

```json
{
  "url": "https://en.wikipedia.org/wiki/Artificial_intelligence",
  "title": "Artificial intelligence - Wikipedia",
  "wordCount": 34968,
  "qualityScore": 100,
  "sourceDomain": "en.wikipedia.org",
  "language": "en",
  "headingCount": 71,
  "paragraphCount": 180,
  "linkCount": 5084,
  "images": 39,
  "contentHash": "603675ced43c",
  "extractionMethod": "cheerio-html2text",
  "cleanText": "## Artificial intelligence\n\nArtificial intelligence (AI) is...",
  "scrapedAt": "2026-05-19T04:40:16.841Z"
}
````

### How Quality Scoring Works

The `qualityScore` (0-100) is computed from four dimensions:

| Dimension | Weight | How it's calculated |
|-----------|--------|---------------------|
| **Length** | 0-35 | `min(35, wordCount / 25)` |
| **Vocabulary diversity** | 0-25 | `min(25, uniqueWords / totalWords * 100)` |
| **Sentence structure** | 0-20 | `min(20, sentenceCount * 1.5)` |
| **Document structure** | 0-20 | `min(20, headingCount * 4 + paragraphCount * 0.5)` |

**Example scores:**

- Wikipedia AI article (34,968 words, 71 headings): **100/100**
- A 500-word blog post with 5 headings and 20 paragraphs: ~60-70
- A 200-word page with no headings: ~25-30 (likely skipped by `minWordCount`)

***

### Use Cases

- **LLM fine-tuning dataset**: Crawl 100 medical research articles to create a specialized healthcare training corpus
- **RAG knowledge base**: Extract clean text from your company docs and blog posts for retrieval-augmented generation
- **Content analysis**: Build a dataset of competitor blog posts with quality scores for content strategy
- **Academic research**: Collect and deduplicate article text from journal websites

***

### Battle-Tested Results

| Test Site | Words | Quality Score | Headings | Paragraphs | Links | Images |
|-----------|-------|---------------|----------|------------|-------|--------|
| Wikipedia — Artificial Intelligence | 34,968 | 100 | 71 | 180 | 5,084 | 39 |

- Deduplication tested across 16 pages — correctly skipped 2 duplicate articles
- Low-quality filtering tested at `minWordCount: 500` — correctly skipped navigation-heavy index pages

***

### Limits & Architecture Constraints

#### Hard Limits

| Limit | Value | Impact |
|-------|-------|--------|
| **Crawler engine** | Cheerio (no browser) | Cannot execute JavaScript or scrape SPAs |
| **Max pages** | 1,000 | Hard ceiling per run |
| **Max crawl depth** | 3 levels | Deep pagination truncated |
| **Same-origin only** | Yes | External links are not followed |
| **Deduplication window** | First 2,000 chars | Pages with identical intros but different bodies flagged as duplicates |

#### Content Extraction Weaknesses

- **Unusual DOM structures**: If a site doesn't use semantic HTML (`<article>`, `<main>`, `.content`), the actor falls back to `body` and may include more noise
- **JavaScript-rendered content**: No Playwright = no JS execution. Content loaded via XHR/fetch is invisible
- **Paywalls & login gates**: Cheerio sees raw HTML — paywall blurbs or login prompts may get extracted as "content"
- **Dynamic lazy loading**: Images and content loaded on scroll are missed

#### When It Works Best

- ✅ Static blogs and documentation sites
- ✅ Wikipedia and wiki-style pages
- ✅ News articles with semantic HTML
- ✅ Corporate knowledge bases and help centers
- ✅ Content-rich pages with clear `article` or `main` tags

#### When It Struggles

- ❌ JavaScript-heavy SPAs (React, Vue, Angular without SSR)
- ❌ Sites with aggressive anti-bot (Cloudflare challenges, CAPTCHA)
- ❌ Pages where main content loads dynamically after page load
- ❌ Heavily paginated tag/category pages (use `excludePatterns` to skip these)

***

### Pricing

- **Free tier**: 5 pages per run
- **Pay-per-result**: $0.005 per page processed
- **Subscription**: $59/month for unlimited runs
