# On writing well

Good prose is clear before it is clever. *Delete* the middle of every sentence and see if it still stands.

Muted syntax means the **text reads as text** — while `structure` stays legible.

v0.2.7 12 words

Features

Built to get out of your way.

Typography

A page, not a text box

Bundled monospace, centered column, muted syntax.

Ctrl+Shift+V

Open in Viewer

Authoring lives here, rendered output in markdown-reader. One keystroke flips you over.

Ctrl+Shift+F

Paragraph focus

Fade everything except the line you're in.

KaTeX · Mermaid

Math & diagrams

Render in the standalone viewer with the same plugins. Nothing to configure.

Ctrl+Shift+H

Export HTML

Self-contained HTML with bundled fonts. PDF lives in markdown-reader.

Tauri · Rust

Native Linux

Small binary. Real file associations. No Electron.

Krill principles

A simple interface.

Focus One app, one job. One file, one window. No tabs, no project trees, no mode pickers — the work in front of you is the work.

Beauty A locked palette, careful typography, chrome that sits still. The apps shouldn't be the part of your desktop you have to forgive.

Simplicity No settings panel, no plugin system, no power-user knobs. If a feature can't be explained in a sentence, it doesn't ship.

Ownership Your files on your disk in their original format. No accounts, no cloud, no telemetry. MIT licensed; build it yourself if you don't trust ours.

Quick install

One-liner — downloads the AppImage to ~/.local/bin, marks it executable, and registers a launcher entry. Re-run to upgrade.
