Money Making Products

There are products, and then there are projects. This is what's currently generating revenue.

MD2Doc
md2doc.com is a dead-simple, free tool that turns AI-generated Markdown into properly formatted Word (.docx), PDF, or Google Docs files in seconds and with excellent formatting fidelity. AI tools (Claude, ChatGPT, Grok, Cursor, etc.) output everything in Markdown. Humans, clients, and most business workflows still want Word documents or Google Docs.Manually copying Markdown into Word has always been painful — tables break, code blocks look like garbage, nested lists get mangled, and you waste time on formatting instead of shipping. md2doc eliminates that friction.
