    • Project mention: I accidentally built a meme search engine | news.ycombinator.com | 2024-04-13

    I steered a friend towards Paperless (and away from an LLM solution) as a way of searching/accessing GBs of architectural PDFs recently - so far, it’s apparently working well for them.

    maybe this is better? https://github.com/clovaai/donut

    I'm not sure

    OCR works pretty good. ocr.space, ocr.best and cotrans.touhou.ai/ are all pretty nice.

  • mmocr

    OpenMMLab Text Detection, Recognition and Understanding Toolbox

    • Project mention: Show HN: BetterOCR combines and corrects multiple OCR engines with an LLM | news.ycombinator.com | 2023-10-28

    Yup! But I'm still exploring options. (any recommendations would be welcomed!) Here are some candidates I'm considering:

    - https://github.com/mindee/doctr

    - https://github.com/open-mmlab/mmocr

    - https://github.com/PaddlePaddle/PaddleOCR (honestly I don't know Mandarin so I'm a bit stuck)

    - https://github.com/clovaai/donut - While it's primarily an "OCR-free document understanding transformer," I think it's worth experimenting with. Think I can sort this out by letting the LLM reason through it multiple times (although this will impact performance)

    - yesterday got a suggestion to consider https://github.com/kakaobrain/pororo - I don't think development is still active but the results are pretty great on Korean text

    • Project mention: Show HN: How do you OCR on a Mac using the CLI or just Python for free | news.ycombinator.com | 2024-01-02

    https://github.com/mindee/doctr/issues/1049

    I am looking for something this polished and reliable for handwriting, does anyone have any pointers? I want to integrate it in a workflow with my eink tablet I take notes on. A few years ago, I tried various models, but they performed poorly (around 80% accuracy) on my handwriting, which I can read almost 90% of the time.
