Built for devs writing docs, students writing papers with equations, and anyone who needs to share markdown fast.
Hey everyone! I built MD Viewer because I've been writing a lot of markdown files for AI agents — system prompts, CLAUDE.md files, agent instructions — and I needed a quick way to preview and share them without pushing to GitHub or opening VS Code.
Most online editors handle basic markdown fine, but none of them rendered my LaTeX equations and Mermaid diagrams in the same place. I'd end up bouncing between three different tools just to check one document.
So I built the tool I wanted: paste your markdown, see everything rendered instantly, and share it with a link. No accounts, no installs, nothing leaves your browser unless you choose to share.
Would love to hear what you think and what features would make this more useful for your workflow!
