Who it is for

Anyone who writes notes, docs or drafts in Markdown and finds a code editor too heavy and Notepad too bare.

What it does

• Editor, split and preview views of the same document.
• Edit a block's Markdown straight from the preview, without turning it into rich text.
• An outline built from the headings, on demand. Drag a heading to move its whole section.
• Find and replace, with the matches highlighted in the preview.
• Task boxes you tick in the preview update the Markdown.
• Recovery copies of unsaved changes, recent and pinned files, drag and drop.
• English or French, light or dark, following the system.

Why I built it

I was tired of simple text and Markdown files opening in Notepad with a trail of tabs I did not want, while full code editors felt absurdly heavy for the job. I wanted something that opened quickly, stayed local, and felt simpler than both.

What I built

• Live editing and preview with search, replacement, task interaction, and sanitized rendering.
• An outline generated from headings, navigation by click, and drag-and-drop movement of complete sections.
• Direct editing of a rendered block from the preview without adding a conversion dependency.
• Atomic saving, per-window recovery copies, recent files, and native desktop packaging.

What it taught me

• A minimal interface can still support deep document operations.
• Local-first software requires careful recovery, file-system, and window-state decisions.
