This FREE OCR can read doctors’ handwriting, complex tables, and mathematical equations.
It’s called Chandra, from Datalab.
And it’s one of the most complete OCRs I’ve seen.
It can process:
Handwritten text Medical notes, filled-out forms, cursive or hard-to-read handwriting.
Complex tables Preserves merged cells, rows, and columns. Ideal for invoices, financial reports, and PDFs with lots of data.
Mathematical formulas Converts equations directly to LaTeX.
Forms Recognizes checkboxes, buttons, and entered values.
Documents with tricky layouts Multi-column text, newspapers, books, and documents with images.
It can return the result in Markdown, HTML, or JSON.
It works in over 40 languages.
To install it:
pip install chandra-ocr
It’s free for personal use.
I’ll leave the link to the repo in the comments
