Hey Product Hunt 👋 I built .md Viewer because my non-technical partner kept asking me "how do I open this .md file?" — files I (or Claude/ChatGPT/Codex) was sending her. Notepad shows it as asterisks and pound signs. Every proper viewer (Typora, Obsidian, VS Code) assumes you're a developer: vault concepts, plugin systems, keyboard shortcuts. I wanted a viewer that's the opposite. So I built one: 🌐 **Lives in your browser** Drag any .md / .html / .pdf onto mdviewer.co and read it instantly. Files never leave your device. No install, no signup, no vault. 🤖 **Built for AI workflows** The free Mac/Windows app watches the folders AI agents write to and auto-reloads. No F5. You read while the AI writes — Claude Code, Codex CLI, Cursor, Aider, any agent that writes files. 🌍 **For everyone, not just developers** 11 languages out of the box (日本語, English, 简体中文, 繁體中文, 한국어, Español, Français, Deutsch, Português, Русский, Italiano). No jargon. Open a file. Read. 💰 **Free is enough for most** Browser version + core desktop features = free forever. Pro is optional, for people running multiple AI agents in parallel: $2/month, $12/year, or $25 lifetime. **Try without anything to install** → https://mdviewer.co **Mac/Windows native app** → mdviewer.co/about#download Would love feedback on: - Does the browser version actually replace the desktop app for you? - What viewer features are missing for your AI workflow? - Pricing — is $25 lifetime right, or should it stay subscription? Source coming open later this year.
