Hey Product Hunt 👋 I built Markdown Tools, and I'm excited to share it here. Every Markdown task I hit — converting a doc, fixing a table, checking whether Discord supports some syntax — sent me to a different ad-covered site with an upload button and a signup wall. Markdown Tools is the opposite: 90 free tools plus a full editor, all running 100% in your browser. Nothing you type or drop in ever leaves your device. A few things worth trying: • The editor: live preview, GFM, footnotes, KaTeX math, Mermaid diagrams, GitHub-style callouts • The cheat sheet: per-feature compatibility across GitHub, Obsidian, Jupyter, Discord, and Slack — downloadable as notes and PDFs • The converters: Markdown ↔ Word / PDF / HTML / BBCode, all client-side No accounts, no uploads, no paywall. I'd love to know which tool you reach for first — and what's missing. I'll be around all day to answer questions!
