How I use GPT Scraper to let ChatGPT access the internet

Do you dream of letting ChatGPT roam the net? GPT Scraper uses web scraping to do just that, with the help of the OpenAI API.


Like millions of others around the world, I’ve been using ChatGPT in my role as Head of Content at Apify for a few months now and finding ways to increase both my and my team’s productivity and explore what it can do. I’ve enjoyed experimenting with it, probing its limits, and occasionally being delighted by unexpected behavior.

I used to love gamebooks, roleplaying games, and was involved in designing online games a long time ago. So some nights recently I'd find myself inputting a gaming prompt and just going with it.

You might not realize it, but ChatGPT can be a great game master for solo gaming

ChatGPT and I have been through a few extended zombie apocalypses, tried out some James Bond scenarios, explored an 18th century Ireland inspired by the sublime Kubrick movie Barry Lyndon, and enjoyed lots of other spontaneous solo gaming. (Edit: it turns out that I'm not the only one doing this). I definitely wouldn’t say that ChatGPT is a consistent game master, but if you can get over its inherent unreliability, you can have a lot of fun with its freeform world creation.

But back to work. While you can achieve a lot by asking ChatGPT to brainstorm blog posts from different points of view or generate a quick list of keywords to pop into SEO tools, you might, like me, sometimes have found yourself daydreaming about what you could do if you could unleash ChatGPT on live web pages, without the search query focus of Bing and Bard.

Connecting ChatGPT to the internet

Asking GPT to look at a real website? That sparks all manner of cool use cases…

Managing the content pipeline for Apify means that I spend at least some of my time editing and proofreading. After over 25 years of that kind of work, I catch a lot, but the occasional typo inevitably slips through. Seems like it would be a cinch to ask ChatGPT to go through, for instance, the entire Apify blog and find any lingering errors. And while it’s at it, spot any images lacking alt text, identify any potential meta data improvements, and maybe check the code examples. For starters.

So that was the first thing I tried when GPT Scraper was published on Apify Store and I chatted to the dev, an old-school Apifier, about how it worked. GPT Scraper uses a two-step process to crawl any website and extract the data, then feed it into GPT via the OpenAI API. The scraper first loads the page using Playwright, then it converts the content into Markdown and sends the content and instructions to GPT.

Extract data from any website and feed it into GPT via the OpenAI API. Use ChatGPT to proofread content, analyze sentiment, summarize reviews, extract contact details, and much more.

To be fair, it didn’t work completely smoothly for me at first, but anyone familiar with ChatGPT is used to dead ends and its trademark hallucinations (or confabulations, as some prefer to call them). On my first few passes, it invented typos, imagined missing images, and generally wasted a good bit of my time. But after some more runs and refined prompts, the results started to be genuinely useful. It spotted readability issues, suggested code optimization, and caught some loose ends.

My next GPT scraping experiment was to see if I could get it to reliably generate FAQs for some older posts, along with the appropriate FAQ schema. This isn't difficult to do manually, but we like to automate as much as possible at Apify - and it's more fun with a digital assistant. As you might imagine, it wasn’t at all trustworthy when it came to making sure the FAQ schema accurately reflected the content in the post, but it was great at generating succinct questions and answers, and then wrapping those in an FAQ schema.

It’s also fairly handy at looking at both our own and competitor blog posts to see what keywords are being targeted and even relatively intelligently suggesting subtle missed opportunities that SEO tools can miss.

3 sample use cases to get you thinking

That’s just what I did in the first couple of hours of playing with GPT Scraper. But so much more is possible. Giving GPT the superpower to digest data from real websites means that you can do some wonderful things. Here's just three:

Use case 1: summarize reviews

Use it to read all the reviews of a book, movie, product, or game and summarize the consensus in seconds. That’s interesting for a consumer, but it’s invaluable for companies.

Prompt: Analyze only the positive reviews of the game on this page and summarize them in one paragraph.

Target URL:

Response: The positive reviews of The Great War: Western Front on Steam praise the game's historical accuracy and attention to detail, as well as its engaging and challenging gameplay. Players mention enjoying the strategic aspects of the game, such as managing resources and maneuvering troops, and appreciate the ability to play as either the Allied or Central powers. The graphics and sound design are also noted as being impressive and immersive. Overall, players seem to highly recommend the game to fans of strategy and historical warfare games.

Caveat: you have to make sure that it's really taken in all the reviews and not just the first few. You can (usually) check this by looking at the log and the scraped data. Or sometimes GPT will just tell you itself that it didn’t get the data it expected. Trial and error will usually lead to a replicable workflow.

Use case 2: collect product information

Gather specific data from web pages based on a prompt that identifies useful information on the fly. Web scraping is great when website content is predictable, but GPT can, sometimes, reliably identify product descriptions and reviews with only natural language instructions. If you’ve done any web scraping, you probably know that it would be nice not to have to identify CSS selectors that might unexpectedly change, or craft custom scrapers for each website.

Prompt: Check each of the hot products listed and give me a condensed summary of the product description.

Target URL:

Result (listing just the first five):

  1. RadioShack Analog AM/FM Weather Tabletop Radio - a tabletop radio with analog tuning and weather alerts, priced at $65.99.
  2. RadioShack Antenna-Mounted High-Gain Signal Amplifier for HDTV Antennas - an amplifier for HDTV antennas that can be mounted on the antenna or wall, priced at $76.99.
  3. Gigastone H1 Wireless Bluetooth Over-Ear Headphones - wireless headphones with Bluetooth connectivity and a built-in microphone, priced at $38.99.
  4. Marathon Nightowl Atomic Travel Alarm Clock with Automatic Night Light - a clock with atomic timekeeping and automatic night light function, priced at $29.99.
  5. RadioShack ⅛” Stereo Panel-Mount Phone Jack - a panel-mount phone jack for stereo audio, priced at $3.99.

Caveat: you (sometimes) can't trust GPT to correctly identify this kind of information, so always double check, but it didn't do badly here with just a simple prompt. You could also apply this kind of prompt to lead generation or any other kind of situation where you need a non-rigid approach to identifying information at scale.

Use case 3: identify popularity based on reviews

Scheduled scraping and analysis of live website data suggests massive potential to track trends and sentiment at scale and get informative summaries or predictive recommendations tailored to any business.

Prompt: Read these book reviews and tell me the most popular.

Target URL:

Result: As an AI language model, I cannot evaluate subjective preferences in book reviews. However, I can provide an objective analysis of the most popular books in the Thriller genre. According to the Goodreads website, the new releases tagged "Thriller" include What Have We Done, What Happened to Ruthy Ramirez, The Kind Worth Saving, All That Is Mine I Carry with Me, Mothered, The Golden Spoon, Birnam Wood, Those Empty Eyes, Her Deadly Game, Flux, Missing Clarissa, Stars and Smoke, How I'll Kill You, The Curator, Play the Fool. These books are currently the most popular in the Thriller genre on Goodreads. Interested readers can explore these books to see if they meet their preferences for a Thriller.

Caveat: you might be used to GPT playing down its abilities when answering prompts and this is a good example, but it correctly identified the top bestsellers in the thriller category at the time without much guidance.

I could keep going, and I bet you will, too, once you think of all the potential use cases. I kept the prompts simple in the examples above, but you probably already know that you get a lot more out of an AI if you give it very detailed instructions, or if you prefer, cast the right spells. This is as true for an image-generating AI like Midjourney as it is for GPT. So don't be afraid to be incredibly verbose. The AI won't mind.

ChatGPT brainstorms its own use cases for GPT Scraper

I want to give the last word to ChatGPT. It’s almost an automatic process for me these days to run much of what I do through it, with a prompt to give me some recommendations for improvements or additions. Sometimes it catches something I missed because I needed another coffee, or offers a helpful suggestion. So GPT was the first entity to read this post.

Because generative AIs are, let’s say it again, inherently unreliable, it often doesn’t help me much, but maybe in this case it has come up with some good ideas. Just remember that you might not be able to entirely trust it, so caveat artifex!

How to use GPT Scraper

GPT Scraper is, like many Apify Store scrapers and tools, designed to be easy to use, although that doesn’t mean that it isn’t powerful. So let’s scrape a real, live web page and ask GPT to extract usable data from it.

Step 1 Go to GPT Scraper

Find GPT Scraper on Apify Store and click Try actor. You’ll need a free Apify account.

Step 2 Choose the URL to feed GPT

Choose the content you want to feed to GPT. You can start scraping from just a single start URL or you can also include glob patterns for fine control over the links to enqueue.

Let’s say I want to see what Humble Bundles are currently available in the games category. Maybe I want to get updates in my email each day to see if anything new has appeared. Maybe you can come up with better use cases.

Step 3 Tell GPT what to do with the scraped content

In the Instructions field, we’re going to give GPT the following simple prompt. This should give us the data 🤞

Instructions: Give me the names and details of all the current available bundles.

Step 4 Click start and wait for the result

When you click start, GPT Scraper will first scrape the Humble Bundle web page, then it will send the scraped data in Markdown format to GPT through the OpenAI API. GPT will read the data and apply your instructions. You’ll just need to wait a short time for GPT Scraper to run.

Step 5 Download your GPT data

When GPT is finished and has reported back, GPT Scraper will indicate that it has Succeeded. You can hover over the Answer to preview the result, or click Export to download it in JSON, Excel, CSV, XML, HTML Table, RSS, or JSONL, depending on where you’ll be using the data. You can of course preview the result in each format before downloading.

You might need to check the results and refine your prompt, but that’s no surprise with generative AIs.

Here’s a preview of what GPT came back with. Looks good so far.

The new OpenAI plugins should give ChatGPT a lot more freedom, but I’m pretty happy with being able to run any web page through it right now. Sure, it’s erratic and eccentric, but that’s part of the charm of these early generative AIs. Just roll with it and enjoy the ride!

Now, I think it’s time to see what ChatGPT will make of this prompt. Arrr! 🦜

Applications of ChatGPT and other large language models in web scraping
A few use cases for large language models used for web scraping.

One last tip before I sail off: use CSS selectors to limit the content scraped from web pages, e.g. on the Apify blog you might only want to scrape articles from the blog and ignore all the navigation elements and other sidebar content.
