Installation

pip install megaparse

Usage

1. Add your OpenAI or Anthropic API key to the .env file

2. Install poppler on your computer (images and PDFs)

3. Install tesseract on your computer (images and PDFs)

4. If you have a mac, you also need to install libmagic brew install libmagic

from megaparse.core.megaparse import MegaParse
from langchain_openai import ChatOpenAI
from megaparse.core.parser.unstructured_parser import UnstructuredParser

model = ChatOpenAI(model="gpt-4o", api_key=os.getenv("OPENAI_API_KEY"))  # or any langchain compatible Chat Models
parser = UnstructuredParser(model=model)
megaparse = MegaParse(parser)
response = megaparse.load("./test.pdf")
print(response)
megaparse.save("./test.md") #saves the last processed doc in md format

Use MegaParse Vision

• Change the parser to MegaParseVision

from megaparse.core.megaparse import MegaParse
from langchain_openai import ChatOpenAI
from megaparse.core.parser.megaparse_vision import MegaParseVision

model = ChatOpenAI(model="gpt-4o", api_key=os.getenv("OPENAI_API_KEY"))  # type: ignore
parser = MegaParseVision(model=model)
megaparse = MegaParse(parser)
response = megaparse.load("./test.pdf")
print(response)
megaparse.save("./test.md")

Note: The model supported by MegaParse Vision are the multimodal ones such as claude 3.5, claude 4, gpt-4o and gpt-4.

(Optional) Use LlamaParse for Improved Results

1. Create an account on Llama Cloud and get your API key.

2. Change the parser to LlamaParser

from megaparse.core.megaparse import MegaParse
from langchain_openai import ChatOpenAI
from megaparse.core.parser.llama import LlamaParser

parser = LlamaParser(api_key = os.getenv("LLAMA_CLOUD_API_KEY"))
megaparse = MegaParse(parser)
response = megaparse.load("./test.pdf")
print(response)
megaparse.save("./test.md") #saves the last processed doc in md format

Use as an API

There is a MakeFile for you, simply use : make dev at the root of the project and you are good to go.

See localhost:8000/docs for more info on the different endpoints !
