Surya
An open-source OCR and layout-analysis toolkit covering text, tables, and reading order in many languages.
Surya is a modern OCR toolkit that does text recognition, line and layout detection, reading-order analysis, and table recognition across a wide range of languages.
It comes from the same team behind Marker and is built to be both accurate and fast on a GPU.
Where it fits
A fit when you want modern, multilingual OCR with strong layout and reading-order detection.
Where it does not fit
