Your files stay on your Mac.
Convertessa reads your .wiki markup files and writes out Word .docx documents, mapping headings, paragraphs, lists, and inline formatting to their Word equivalents.

No cloud. No account. No upload. Every conversion happens entirely on-device, using the power already in your Mac. What you convert is nobody’s business but yours.
Script conversions, wire them into your build, or batch a folder from the terminal. The same engine, no GUI required.
