michellepace/word-document-corrector-claude — reverse-engineered prompt

Build me a simple Google Colab notebook that lets me upload a Word document and have Claude Sonnet correct it better than Microsoft Word. I want it to handle large .docx files by breaking them into manageable parts, fixing grammar, spelling, and awkward word choices, then putting everything back together without changing the writer’s meaning or overall style.

The result should be easy to review, with the corrections shown in colour in an HTML output so I can clearly see what changed. Please preserve the document structure as much as possible.

I also want some built in checks so this feels trustworthy, like making sure the corrected version keeps roughly the same length, structure, and meaning as the original. If it makes sense, include a few prompt and code evaluations too, so I can tell whether the corrections are actually good.

Keep it practical and easy to run from one notebook. You can look up current docs online if needed.
