What Hacker News says
3 sourcesGood:
- no cloud service required, can run on local Nvidia GPU
- outputs a single stream of text with the correct reading order (even for multi column PDF)
- recognizes handwriting and stuff
Bad:
- doesn't seem to extract the text within diagrams (which I guess is fine because that text would be useless to an LLM)
OP is the demo page, which lets you OCR 10 pages.
The code needs an Nvidia GPU to run: https://github.com/allenai/olmocr
Not sure if the VRAM requirements because I haven't tried running locally yet.
In OlmOCR: Open-source tool to extract plain text from PDFsLooks cool!
May also be interested in Allen AI's OCR tool olmOCR they just released too [1][2]. They say "convert a million PDF pages for only $190 USD".
