Instead of Tesseract OCR
Tesseract OCR alternatives
Tesseract OCR is a free, open-source engine and command-line program for extracting printed text from images. Its LSTM-based engine recognizes text by line, and a legacy engine remains available for Tesseract 3 compatibility. It supports more than 100 languages and image formats such as PNG, JPEG, and TIFF, with outputs including plain text, hOCR, PDF, TSV, ALTO, and PAGE. Developers can use its C or C++ API and wrappers for other languages across desktop systems, Android, APIs, and self-hosted setups.

A switch may make sense if you need handwriting recognition, document layout analysis, a graphical editing interface, broader input types, or a workflow focused on scanned PDFs. Tesseract has no built-in GUI, accepts images, and may require improved source-image quality for better OCR. Compare alternatives by their editing and layout controls, supported platforms and inputs, output structure, and role in a larger document workflow. In particular, OCRmyPDF uses Tesseract itself, so its value is PDF processing rather than a different recognition engine.
