About Umi-OCR
Umi-OCR is a free, open-source optical character recognition (OCR) program that runs offline. It recognizes text from screenshots, batches of local images, and PDF documents, and it includes OCR support for multiple languages. The software is distributed as a Windows release package that is extracted and run as Umi-OCR.exe, without a separate installation step. The source states that it is compatible with Windows 7 x64 and later.
The program includes a screenshot OCR page, a batch OCR page, and paragraph merge options that control how recognized lines are arranged, including single lines, natural paragraphs, code blocks, and vertical layouts. Recognized text can be saved as txt, jsonl, md, or csv files. The project also describes command-line and HTTP API calling methods. The source says the offline engine's speed depends on the computer's performance. Pricing is unknown.
