Here's a quick example to get you started with extract_thinker. This example demonstrates how to load a document using Tesseract OCR and extract specific fields defined in a contract.
import os
from dotenv import load_dotenv
from extract_thinker import DocumentLoaderTesseract, Extractor, Contract
load_dotenv()
cwd = os.getcwd()
class InvoiceContract(Contract):
invoice_number: str
invoice_date: str
tesseract_path = os.getenv("TESSERACT_PATH")
test_file_path = os.path.join(cwd, "test_images", "invoice.png")
extractor = Extractor()
extractor.load_document_loader(
DocumentLoaderTesseract(tesseract_path)
)
extractor.load_llm("claude-3-haiku-20240307")
result = extractor.extract(test_file_path, InvoiceContract)
print("Invoice Number: ", result.invoice_number)
print("Invoice Date: ", result.invoice_date)
You can also split and process documents using extract_thinker. Here's how you can do it:
import os
from dotenv import load_dotenv
from extract_thinker import DocumentLoaderTesseract, Extractor, Process, Classification, ImageSplitter
load_dotenv()
class DriverLicense(Contract):
# Define your DriverLicense contract fields here
pass
class InvoiceContract(Contract):
invoice_number: str
invoice_date: str
extractor = Extractor()
extractor.load_document_loader(DocumentLoaderTesseract(os.getenv("TESSERACT_PATH")))
extractor.load_llm("gpt-3.5-turbo")
classifications = [
Classification(name="Driver License", description="This is a driver license", contract=DriverLicense, extractor=extractor),
Classification(name="Invoice", description="This is an invoice", contract=InvoiceContract, extractor=extractor)
]
process = Process()
process.load_document_loader(DocumentLoaderTesseract(os.getenv("TESSERACT_PATH")))
process.load_splitter(ImageSplitter())
path = "..."
split_content = process.load_file(path)\
.split(classifications)\
.extract()
# Process the split_content as needed
The extract_thinker
project is inspired by the LangChain ecosystem, featuring a modular infrastructure with templates, components, and core functions to facilitate robust document extraction and processing.
While LangChain is a generalized framework designed for a wide array of use cases, extract_thinker is specifically focused on Intelligent Document Processing (IDP). Although achieving 100% accuracy in IDP remains a challenge, leveraging LLMs brings us significantly closer to this goal.

skyvern
Skyvern automates browser-based workflows using LLMs and computer vision. It provides a simple API endpoint to fully automate manual workflows, replacing brittle or unreliable automation solutions. Traditional approaches to browser automations required writing custom scripts for websites, often relying on DOM parsing and XPath-based interactions which would break whenever the website layouts changed. Instead of only relying on code-defined XPath interactions, Skyvern adds computer vision and LLMs to the mix to parse items in the viewport in real-time, create a plan for interaction and interact with them. This approach gives us a few advantages: 1. Skyvern can operate on websites it’s never seen before, as it’s able to map visual elements to actions necessary to complete a workflow, without any customized code 2. Skyvern is resistant to website layout changes, as there are no pre-determined XPaths or other selectors our system is looking for while trying to navigate 3. Skyvern leverages LLMs to reason through interactions to ensure we can cover complex situations. Examples include: 1. If you wanted to get an auto insurance quote from Geico, the answer to a common question “Were you eligible to drive at 18?” could be inferred from the driver receiving their license at age 16 2. If you were doing competitor analysis, it’s understanding that an Arnold Palmer 22 oz can at 7/11 is almost definitely the same product as a 23 oz can at Gopuff (even though the sizes are slightly different, which could be a rounding error!)
