[Pytesseract](https://pypi.org/project/pytesseract/) is a Python wrapper for [Google’s Tesseract OCR engine](https://github.com/tesseract-ocr/tesseract), used for recognizing and extracting text from images. It works on a wide range of image types (e.g., JPEG, PNG, TIFF) and supports over 100 languages, including Chinese, Arabic, and Devanagari.

Tesseract uses a character-level LSTM model and runs entirely on CPU, making it easy to deploy in low-resource environments. While it’s not state-of-the-art for complex layout or scene text, it’s fast, scriptable, and widely supported — ideal for lightweight OCR use cases.

Tesseract’s fast CPU performance and no-frills setup make it great for small-scale OCR, but it’s not optimized for high-volume pipelines or scene text recognition.
