Built in Rust with egui — no Electron, no Chromium. Your manuscript stays plain markdown files in plain folders; Smaragd adds the binder, the metadata, and the typesetting on top.
Binder, editor, preview, corkboard, metadata, backlinks, and tags are all tabs in one shared layout — drag, split, float, or dock any of them, and it persists across restarts.
A project is just a folder of .md files. A small .smaragd/project.json stores ordering and folder roles — delete it and it's still a perfectly readable folder of markdown.
Research/Trash/Templates folder roles, built-in Blank/Novel/Nonfiction/Screenplay templates, and Story Genius–style corkboard cards with Alpha Point, Cause, Effect, and Why It Matters.
Obsidian-style [[links]] with autocomplete, a full backlinks panel, and frontmatter + inline #tags — all resolved live across the project.
DOCX, EPUB, and print-ready PDF from one shared Style. PDF is genuine typesetting via the embedded Typst compiler — running headers, drop caps, widow/orphan control, no LaTeX install, no network.
Maximizes the window, hides every other tab, and dims every paragraph but the one you're writing — a typewriter, distraction-free view one keypress away (F9).
Gruvbox, Dracula, Nord, Catppuccin, Tokyo Night, and more built in — or drop a .toml file into the config directory for your own theme, style, or template.
Plugins in the embedded Rhai language add custom : commands, keyboard shortcuts, and save-time text transforms — project-local plugins stay opt-in.
Commit, push, and pull from the Versions menu, modeled on the Obsidian Git plugin — network operations run in the background so the UI never freezes.
Work/break cadence with a status-bar countdown that keeps ticking whether or not its tab is open — configurable durations and session count.
Native builds for Linux, Windows, and macOS — see the latest release for exact filenames.
