A distraction-free markdown writer that reads and writes plain .md files on your own disk. Built for long-form work: manifestos, essays, notes, drafts.

The editor stays out of your way. Headings, lists, code blocks and math render in place; the line under your cursor switches to raw markdown so you can edit it like a regular text file. Nothing leaves your machine.

npm install
npm start

Then open http://localhost:3000.

On first launch the server reads config.json (created next to server.js) to find your workspace folder. The default points at C:\DEV\coding\nexearch\solutions\manifest; change it from the gear icon in the sidebar, or edit config.json directly.

The workspace is a folder you own. Scriptorium mirrors its structure 1:1:

workspace/
  Manifestos/                      <- section (sidebar group)
    on-time.md                     <- document
    against-clarity.md
  Essays/
    welcome.md
  ideas/                           <- sentence-cloud source
    quantum.md                     <- one theme per file
    consciousness.md

• A subfolder is a section. Rename a folder, the section renames.
• A .md at the root lands in the implicit "General" section.
• Drag a .md onto a section in the sidebar to import it.
• ideas/*.md files hold the right-panel cloud. Each line starting with - is an idea; - [x] ... means archived. The files are rewritten in place whenever you click on an idea, so editing them from outside the app works too.

Filenames are derived from the document title (slugified, ASCII). Rename a title and the file gets renamed on next save. Section renames are immediate.

A floating toolbar appears whenever you select text. A small + button shows up in the gutter on the active line; click it for headings, lists, checkbox, quote, code block, divider.

Standard CommonMark plus a few extras used by Obsidian/GitHub:

• Headings, lists, ordered lists, task lists (- [ ] / - [x])
• Bold, italic, strikethrough, underline (via <u>), inline code, highlight (==text==)
• Links, wikilinks ([[name]]), images
• Blockquotes and Obsidian-style callouts (> [!info] Title)
• Tables (single-line cells)
• Horizontal rules
• Fenced code blocks with syntax highlighting via highlight.js (common languages bundled; Rust, Go, YAML, Dockerfile, LaTeX added explicitly)
• Inline LaTeX ($x^2$) and display LaTeX ($$ \int ... $$) via KaTeX
• Footnote references ([^1])

The renderer is line-oriented: code fences and tables get grouped after the fact so they look like real blocks while still letting you edit any line in source.

• Node.js + Express on the server side. The whole API is in server.js.
• No framework on the client: public/{index.html, app.js, style.css}.
• highlight.js and KaTeX are loaded from a CDN; they degrade gracefully if offline (formulas show as inline code, blocks lose syntax colours but stay readable).
• Fonts: Newsreader (body), Inter (UI), JetBrains Mono (code).
