Project mention: Show HN: Kreuzberg – Modern async Python library for document text extraction | news.ycombinator.com | 2025-02-15https://github.com/PaddlePaddle/PaddleOCR
Personally I‘ve used Tesseract before but the results were underwhelming, so I‘m curious how Paddle OCR performs in comparison.

MinerU
A high-quality tool for convert PDF to Markdown and JSON.一站式开源高质量数据提取工具，将PDF转换成Markdown和JSON格式。
The system they tested are mostly used as a part of a larger system. A more fair comparison would be to use something like MinerU [1] and proper benchmark like the OHR Bench and Reductos table bench. This paper is really bad...

Project mention: Show HN: Documind – Open-source AI tool to turn documents into structured data | news.ycombinator.com | 2024-11-18Got excited about an open-source tool doing this.
Alas, i am let down. It is an open-source tool creating the prompt for the OpenAI API and i can't go and send customer data to them.
I'm aware of https://github.com/clovaai/donut so i hoped this would be more like that.

multimodal llm would of course blow it all out the water, so some llama3-like model is probably SOTA in terms of what you can run yourself. something like https://huggingface.co/blog/idefics2
