thepi.pe

Extract clean markdown from PDFs URLs, slides, videos, and more, ready for any LLM. ⚡

thepi.pe is a package that can scrape clean markdown and extract structured data from tricky sources, like PDFs. It uses vision-language models (VLMs) under the hood, and works out-of-the-box with any LLM, VLM, or vector database. It can be used right away on a hosted cloud, or it can be run locally.

Features 🌟

• Scrape clean markdown, tables, and images from any document or webpage
• Works out-of-the-box with LLMs, vector databases, and RAG frameworks
• AI-native filetype detection, layout analysis, and structured data extraction
• Accepts a wide range of sources, including Word docs, Powerpoints, Python notebooks, GitHub repos, videos, audio, and more

Get started in 5 minutes 🚀

thepi.pe can read a wide range of filetypes and web sources, so it requires a few dependencies. It also requires vision-language model inference for AI extraction features. For these reasons, we host an API that works out-of-the-box. For more detailed setup instructions, view the docs.

pip install thepipe-api

Hosted API (Python)

You can get an API key by signing up for a free account at thepi.pe. It is completely free to try out. The, simply set the THEPIPE_API_KEY environment variable to your API key.

from thepipe.scraper import scrape_file
from thepipe.core import chunks_to_messages
from openai import OpenAI

# scrape clean markdown
chunks = scrape_file(filepath="paper.pdf", ai_extraction=False)

# call LLM with scraped chunks
client = OpenAI()
response = client.chat.completions.create(
    model="gpt-4o",
    messages=chunks_to_messages(chunks),
)

Local Installation (Python)

For a local installation, you can use the following command:

pip install thepipe-api[local]

You must have a local LLM server setup and running for AI extraction features. You can use any local LLM server that follows OpenAI format (such as LiteLLM) or a provider (such as OpenRouter or OpenAI). Next, set the LLM_SERVER_BASE_URL environment variable to your LLM server's endpoint URL and set LLM_SERVER_API_KEY. the DEFAULT_AI_MODEL environment variable can be set to your VLM of choice. For example, you would use openai/gpt-4o-mini if using OpenRouter or gpt-4o-mini if using OpenAI.

For full functionality with media-rich sources, you will need to install the following dependencies:

apt-get update && apt-get install -y git ffmpeg tesseract-ocr
python -m playwright install --with-deps chromium

When using thepi.pe locally, be sure to append local=True to your function calls:

chunks = scrape_url(url="https://example.com", local=True)

You can also use thepi.pe from the command line:

thepipe path/to/folder --include_regex .*\.tsx --local

How it works 🛠️

thepi.pe uses computer vision models and heuristics to extract clean content from the source and process it for downstream use with language models, or vision transformers. The output from thepi.pe is a list of chunks containing all content within the source document. These chunks can easily be converted to a prompt format that is compatible with any LLM or multimodal model with thepipe.core.chunks_to_messages, which gives the following format:

[
  {
    "role": "user",
    "content": [
      {
        "type": "text",
        "text": "..."
      },
      {
        "type": "image_url",
        "image_url": {
          "url": "data:image/jpeg;base64,..."
        }
      }
    ]
  }
]

You can feed these messages directly into the model, or alternatively you can use chunker.chunk_by_document, chunker.chunk_by_page, chunker.chunk_by_section, chunker.chunk_semantic to chunk these messages for a vector database such as ChromaDB or a RAG framework. A chunk can be converted to LlamaIndex Document/ImageDocument with .to_llamaindex.

⚠️ It is important to be mindful of your model's token limit. GPT-4o does not work with too many images in the prompt (see discussion here). To remedy this issue, either use an LLM with a larger context window, extract larger documents with text_only=True, or embed the chunks into vector database.
