AIPDF: Simple PDF OCR with GPT-like Multimodal Models

Screw traditional OCRs or heavy libraries to get data from PDFs, GenAI does a better job!

AIPDF is a stand-alone, minimalistic, yet powerful pure Python library that leverages multi-modal gen AI models (OpenAI, llama3 or compatible alternatives) to extract data from PDFs and convert it into various formats such as Markdown or JSON.

Installation

pip install aipdf

in macOS you will need to install poppler

brew install poppler 

Quick Start

from aipdf import ocr

# Your OpenAI API key   
api_key = 'your_openai_api_key'

file = open('somepdf.pdf', 'rb')
markdown_pages = ocr(file, api_key)

Ollama

You can use with any ollama multi-modal models

ocr(pdf_file, api_key='ollama', model="llama3.2", base_url= 'http://localhost:11434/v1', prompt=...)

Any file system

We chose that you pass a file object, because that way it is flexible for you to use this with any type of file system, s3, localfiles, urls etc

From url

pdf_file = io.BytesIO(requests.get('https://arxiv.org/pdf/2410.02467').content)

# extract
pages = ocr(pdf_file, api_key, prompt="extract tables, return each table in json")

From S3

s3 = boto3.client('s3', config=Config(signature_version='s3v4'),
                  aws_access_key_id=access_token,
                  aws_secret_access_key='', # Not needed for token-based auth
                  aws_session_token=access_token)


pdf_file = io.BytesIO(s3.get_object(Bucket=bucket_name, Key=object_key)['Body'].read())
# extract 
pages = ocr(pdf_file, api_key, prompt="extract charts data, turn it into tables that represent the variables in the chart")

Why AIPDF?

1. Simplicity: AIPDF provides a straightforward function, it requires minimal setup, dependencies and configuration.
2. Flexibility: Extract data into Markdown, JSON, HTML, YAML, whatever... file format and schema.
3. Power of AI: Leverages state-of-the-art multi modal models (gpt, llama, ..).
4. Customizable: Tailor the extraction process to your specific needs with custom prompts.
5. Efficient: Utilizes parallel processing for faster extraction of multi-page PDFs.

Requirements

• Python 3.7+

We will keep this super clean, only 3 required libraries:

• openai library to talk to completion endpoints
• pdf2image library (for PDF to image conversion)
• Pillow (PIL) library
