Webpage to LLM Ready Input Text
Pre-processing webpage before giving it as input to the LLM improves extraction/scraping accuracy especially if you want to extract website and image links, tables required for most scraping operations like scraping an e-commerce website.
Use this library to turn any webpage/url to LLM friendly text. Fully open source alternative to firecrawl and jina reader api.
You can also refer to my other repo AI-web_scraper for direct scraping tools that will do web search and scrapes multiple links with just a simple query. It supports multiple LLMs, Web Search and Extracts Data as per your written instructions.

Update for Old Users:
We have switched from Selenium to Playwright for concurrent web scraping support. Kindly install the required playwright dependencies as given below.
Install:
# install llm-reader
pip install git+https://github.com/m92vyas/llm-reader.git
# install playwright dependencies. we are using playwright for async/concurrent web scraping support.
playwright install # to download browser.
playwright install-deps
Import:
from url_to_llm_text.get_html_text import get_page_source # you can also use your own code or other services to get the page source
from url_to_llm_text.get_llm_input_text import get_processed_text # pass html source text to get llm ready text
Get processed LLM input text:
url= <url_to_scrape>
# get html source text
# You can use your own function to get the html source text
page_source = await get_page_source(url)
# get LLM ready input text from html source text
llm_text = await get_processed_text(page_source, url)
print(llm_text)
### or use asyncio ###
# import asyncio
# url = <url_to_scrape>
# # creating a simple function here. View documentation for more parameter details.
# async def get_llm_ready_text(url: str) -> str:
# page_source = await get_page_source(url)
# llm_text = await get_processed_text(page_source, url)
# return llm_text
# llm_text = asyncio.run(get_llm_ready_text(url))
# print(llm_text)
Example Usage:
suppose we want to scrape the product name, main product page link, image link and price from the url “https://www.ikea.com/in/en/cat/corner-sofas-10671/” using any openai model.
import requests
from url_to_llm_text.get_html_text import get_page_source
from url_to_llm_text.get_llm_input_text import get_processed_text
url = "https://www.ikea.com/in/en/cat/corner-sofas-10671/"
# get page html source text using this library function or any other means
page_source = await get_page_source(url)
# get llm ready text and pass the text to your LLM prompt template
llm_text = await get_processed_text(page_source, url)
# prompt template
prompt_format = """extract the product name, product link, image link and price for all the products given in the below webpage. The format should be:
{{
"1": {{
"Product Name": ,
"Product Link": ,
"Image Link": ,
"Price":
}},
"2": {{
"Product Name": ,
...
}},
}}
webpage:
{llm_friendly_webpage_text}
"""
# calculate tokens and truncate the llm_text to fit your model context length and your requirements. sometimes you may need only initial part of the webpage.
# below we are manually truncating to 40000 characters. create a seperate function as per your need.
prompt = prompt_format.format(llm_friendly_webpage_text=llm_text[:40000])
api_key = <your openai api key>
headers = {
"Content-Type": "application/json",
"Authorization": f"Bearer {api_key}"
}
payload = {
"model": "gpt-4o-mini",
"messages": [
{
"role": "user",
"content": [
{

}
]}],
'seed': 0,
"temperature": 0,
"top_p": 0.001,
# "max_tokens": 1024, # if you want to limit the output tokens. this may keep the output json structure incomplete.
"n": 1,
"frequency_penalty": 0, "presence_penalty": 0
}
response = requests.post("https://api.openai.com/v1/chat/completions", headers=headers, json=payload)
print(response.json()['choices'][0]['message']['content'])

To Scrape and Crawl without getting Blocked:
- You can replace the
get_page_source function with any paid API or use your own proxies or scraping setup to get the page source. e.g. you can use a pay-as-you-go option like Scrappey to get page source without getting blocked and then pass the HTML to get_processed_text function to get LLM text for free.
- You can use this guide to get an pay as you go option compared to subscription based solutions like Firecrawl.
- You can save in your subscription cost and also in downstream LLM usage cost.
