🤖 AI Web Scraper — LLM-Powered Extraction vs Diffbot, Browse AI & ScrapingBee

Pay-per-result AI-driven web scraper — point it at any URL with a natural-language extraction prompt, and it returns structured JSON. No CSS selectors, no XPath, no schema mapping. Built for analysts, indie developers, and growth teams as a no-seat-license alternative to Diffbot ($299-899+/mo with Automatic Extraction API), Browse AI ($48.75-149+/mo), ScrapingBee ($49-249+/mo), Apify's own Web Scraper actor (requires JS knowledge), Octoparse ($75-249/mo), and ParseHub.

Solo founders, growth teams, and analysts pick this actor instead of Diffbot or Browse AI because there is no robot-by-robot recording phase — you write a single sentence describing what you want and it just works for one-off and recurring extractions. It is a drop-in alternative to ScrapingBee when you don't want to maintain selectors as target sites change layouts.

What You Get Per Extraction

Each dataset item is a flat JSON record matching the schema you describe in your prompt:

• Top level: any fields you ask for in the prompt (title, price, author, published_at, etc.)
• _source_url, _extracted_at, _model_used, _extraction_cost_usd
• _confidence_score — 0-1, LLM self-reported certainty
• _raw_html_chunk — optional, the chunk fed to the LLM (for debugging)
• For multi-record pages (lists / cards / tables): items — array, each conforming to your prompt schema

The LLM picks the right fields off any reasonably-structured page. Works on product pages, articles, profile pages, listing cards, comparison tables, FAQs — anything where a human could eyeball the structure.

Use Cases

• Founders shipping a quick MVP — extract competitor pricing tables without writing a selector
• Growth teams building one-off lead lists — point at a directory site, describe the field shape, done
• Analysts running ad-hoc research — pull every "AI safety researcher" profile from a few directories without coding
• Notion / Airtable users — pipe arbitrary pages into a structured table via Zapier + this actor
• Newsletter operators — auto-summarize news pages with a single prompt
• VC scouts — extract founder bios from accelerator class pages instantly
• Replace one-off Python+BeautifulSoup scripts — say what you want, get JSON

Quick Start

    "urls": ["https://example.com/products/123"],
    "prompt": "Extract: product name, price, currency, in_stock boolean, average rating, total review count",
    "model": "gpt-4o-mini"
})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item)

FAQ

Q: How is this different from Diffbot or Browse AI? Diffbot uses computer-vision + classical NLP and has a fixed set of APIs (article, product, image, etc.). Browse AI records UI actions per "robot" — typically 10-20 minutes per site. This actor uses an LLM at inference time, so a single English sentence handles any site shape.

Q: Which LLM does it use? Default is GPT-4o-mini for cost; switch to gpt-4o or claude-sonnet for harder pages. BYOK supported.

Q: What's the confidence score? The LLM emits its own self-reported certainty (0-1). Use it to flag low-confidence extractions for human review.

Q: Does it handle JavaScript-rendered pages? Yes — pages are rendered in headless Chromium before LLM extraction.

Q: What about pages with 100s of items (search results, catalogs)? Use items schema in your prompt — the LLM returns an array. The actor paginates automatically if you provide a pageParam.

Q: Schema stability across runs? Stable as long as your prompt is stable. The LLM follows your described schema deterministically (we set temperature=0).

How NexGenData Pricing Works

• Actor Start: a single-event charge each time you spin the actor up (scaled to memory size)
• Result / item: charged per item written to the default dataset
• No charge for retries, internal proxy rotation, or failed sub-requests — those are absorbed by the platform
