Markdown Preview is the simplest way to turn raw markdown text into clean, formatted content you can actually read. If you use AI tools like ChatGPT, Claude, Copilot, or other chatbots and agents, you have probably received markdown-formatted responses: text full of hashtags, asterisks, brackets, and pipes. Markdown Preview lets you paste that text in and instantly see it rendered as proper headings, bold text, lists, tables, blockquotes, and more. No sign-up. No ads. No subscriptions. Just a fast, focused utility that does one thing well. HOW IT WORKS Open the app and paste or type your markdown text in the editor Tap Preview to see your text beautifully formatted Save documents to revisit them anytime That is it. Switch between Edit and Preview with a single tap. WHAT MARKDOWN PREVIEW SUPPORTS • Headings (H1 through H6) • Bold and italic text • Bullet lists and numbered lists • Tables with headers and rows • Blockquotes • Inline code and code blocks • Links • And more standard markdown syntax BUILT FOR REAL WORKFLOWS AI assistants and coding tools output markdown constantly. Whether you are reviewing a report from an AI agent, reading documentation, checking notes from a developer, or just want to preview a README file before pushing it to GitHub, Markdown Preview gives you a distraction-free reading experience. Copy a markdown response from any chatbot, paste it into Markdown Preview, and read it the way it was meant to be read. SAVE FOR LATER Found a markdown document you want to keep? Save it directly in the app and come back to it whenever you need. Your saved documents stay on your device, organized and easy to find. WORKS ON ALL YOUR DEVICES Available on iPhone, iPad, and Mac.

WHY MARKDOWN PREVIEW? • 100% free with no ads or in-app purchases • No account required • Lightweight and fast • Clean, minimal design • Works completely offline • Respects your privacy (no data collected) We use the standard Apple End User License Agreement (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Markdown Preview is made by an independent developer who wanted a simple tool for reading AI-generated markdown output. If you find it useful, a rating or review on the App Store goes a long way.
