Convert PDFs, Word docs, and more to clean Markdown for AI context windows.
u/kirillzubovsky · Reddit
Selling t0md.com – Privacy-first multi-format to Markdown converter A few months ago I was dumping research PDFs and Word docs into Claude and Cursor and watching the token bill climb for no good reason. Heavy formats are terrible for context windows as the agents have to first convert the documents, then parse the MD files, then do the processing. I thought I could help the agents, and I built t0md.com. However exciting it was to make something quickly that solves a big problem, it's not

Convert messy supplier catalogs to Shopify-ready CSV files with AI.
u/captain_sauce_code · Reddit
I built a tool that turns messy supplier PDFs and spreadsheets into Shopify CSVs I'm a software developer in Australia, building this on the side around a full time job. The itch: dropshippers and small Shopify stores get product catalogs from suppliers as PDFs or ugly spreadsheets, then hand-retype them into Shopify's import CSV. While building I ran real supplier catalogs through it and the files were worse than you'd think. Split product titles, columns that drift halfway down the page,
