open.md

Local Markdown reader · 0.1.0

Read the file.
Keep the file.

open.md turns local Markdown and plain-text files into a focused desktop reading view with optional in-place editing. It never fetches remote images. Opening a file is read-only until you choose Edit and save.

The actual interface

The document stays in charge.

Controls stay at the edges until they are needed. The same reading structure holds in a narrow window.

This generated study uses the original Read, Help, and Resize captures above as references. It is an illustrative composition, not a screen recording; use the stills for interface details.

How it works

Open, read, edit.

  1. 01

    Open a local file.

    Choose it, drop it into the window, or use the operating system’s Open with flow.

  2. 02

    Read the rendered document.

    Markdown, highlighted code, Mermaid diagrams, and bounded local images share one reading surface.

  3. 03

    Edit when you need to.

    Use Rendered Edit for live preview or Source Edit for the complete file. Optional block tools, themes, zoom, and the minimap stay available.
