When you need to bring document reading into a product, compare OCR options by the work they can handle and the way they fit your stack. Handwriting OCR, table extraction, and structure extraction distinguish different document needs; maximum file size and asynchronous processing help clarify processing constraints. SDK languages, free-plan availability, and paid-from pricing add implementation and access context. The ranking opens with OCR.space, Tesseract OCR, and Mistral OCR, followed by OCRmyPDF and Amazon Textract AnalyzeExpense. Check those capabilities against the documents your team expects to process, and consider which extraction features and integration details are essential for your workflow.
