I built Markdown Preview because I kept pasting drafts into online Markdown viewers and didn’t love the idea of sensitive docs hitting someone else’s server. I wanted something that stays fully in the browser. What it does: • Live split-pane editor + preview. Nothing is uploaded for rendering • Local AI text tools (Write / Rewrite / Proofread) on supported Chrome builds • Local text-to-speech with word highlighting • Mermaid, GitHub alerts, syntax highlighting, Present/Slides modes • Shareable links (Markdown compressed into the URL hash, still client-side) • Installable PWA. Works offline and can open .md files on Chromium desktop Still rough: mobile layout, very long share links can get truncated by some apps, and the on-device AI menu only appears when Chrome exposes those APIs. I’d love feedback, especially: 1. Would you trust this for private/work docs? What would make that clearer? 2. What’s missing before you’d bookmark or install it (export, more themes, better mobile, etc.)? Thanks for checking it out! I’ll be around all day to reply.
