REAL INTERFACE / DESKTOP

Less noise. More room for your ideas.

01 / Overview

Let the tool leave room for ideas.

Writing and reading

CodeMirror 6, live preview, slash commands, search, focus, presentation, and navigation between linked documents.

Local workspace

Local explorer with folders, favorites, recents, archive, trash, history, assets, and an inspector.

Export your work

Download Markdown, export HTML and ZIP assets, copy Markdown/HTML, and send a note to NEXUS OS on Android.

02 / The problem

Writing, organizing, and reviewing should not mean jumping between tools.

03 / The approach

A connected workflow.

The interface connects editor, preview, and local library. A document graph links notes, while the command palette, inspector, and export tools stay within reach.

markEDdown → NEXUS OS / Android

From document to note, with your confirmation.

Choose Enviar a NexusOS in Exportar, or Herramientas → Exportar in mobile Pocket. Android opens its sharing sheet; NEXUS OS lets you review the title and Markdown before saving. Cancel discards the draft.

This is a one-time text copy, not synchronization. The original stays unchanged; browser-local images, categories, project assignments, and relationships are not transferred. A NEXUS OS build with the receiver is required; release 0.1.2 predates it. The flow was verified on a Tab S8 using an isolated QA app.

If Web Share is unavailable, download the .md file to keep it; the v1 receiver accepts shared text, not .md files. Native PDF export and full workspace backup remain outside the documented scope.

05 / Product decisions

Built with intention.

Editing and reading share the same workspace. Organization and inspection panels appear when needed, keeping documents in the browser and background artwork outside the editor content.

06 / Stack & privacy

Behind the interface.

Vite / CodeMirror 6 / Marked / Vanilla JavaScript

Documents, preferences, and images are stored in browser localStorage. This storage is not encrypted: export copies to preserve your work.
