GRSMD: Markdown Viewer to Keep You in the Zone

Just press [R] to update AI result

---

Why?

I have AI rewrite my docs all the time.
VS Code preview works fine for a single file
— but once you're juggling multiple .md files,
it gets sluggish with Mermaid diagrams, math blocks, and long files

That little lag — just enough to break the flow.

With GRSMD, each file just opens in a new browser tab. No friction, no slowdown.

What I built

GRSMD is a Markdown viewer that runs entirely in your browser — no install, no backend.

I just added a reload feature so you never have to re-drag a file again.

How it works

1. Drop a .md onto GRSMD
2. Have AI update the file (review comments, rewrites, whatever)
3. Press [R] on GRSMD (or click the [Re-load] button) → The updated content re-renders — scroll position preserved

Who is this for?

• You use AI to draft or edit Markdown (docs, READMEs, blog posts)
• You want to preview multiple files without leaving your browser
• You care about privacy — no data leaves your machine

Workflow

Bonus — code files too

Drop .py, .js, .json, or any non-.md text file

— you get syntax highlighting with line numbers. R key reloads these as well.

Quietly useful for code review.
