OCRmyPDF vs olmOCR

Short answer

OCRmyPDF: Command-line tool and Docker image that adds a searchable OCR text layer to scanned PDFs, with a watched-folder service. olmOCR: Ai2's vision-language OCR that turns PDFs and scans into clean Markdown, including tables, equations and handwriting. Both are in our Document processing category.

Choose OCRmyPDF if you want: no GPU server needed, an actively maintained project (olmOCR is stale) and larger community (35.2k vs 19.8k GitHub stars).

Choose olmOCR if you want: fewer license conditions (Permissive vs Copyleft (GPL)).

OCRmyPDF publishes no official RAM figure, so we cannot compare hosting cost directly.
