There are plenty of Markdown editors out there. Bokuchi exists because:

Free and open source, actively developed. Typora is now paid, and MarkText is no longer actively maintained.
No vault, no lock-in. Bokuchi opens plain .md / .txt files directly, like a text editor — not a knowledge base.
Private by design. Works completely offline. No account, no telemetry.
Web-faithful preview. Bokuchi renders Markdown with the same web technologies used by GitHub and your browser — genuine KaTeX, Mermaid, and Marp, not reimplementations. If it renders on the web, it renders in Bokuchi.

Live preview with synchronized scrolling, interactive checkboxes, and a Markdown toolbar
Variable system: define {{variables}} per file or globally and reuse them across documents
Marp presentations: preview slide decks with marp: true front-matter, including custom themes
Math & diagrams: KaTeX expressions and Mermaid diagrams out of the box
Lightweight: small download size and instant startup — no bundled browser engine, thanks to Tauri
Tabs with session restore and external file-change detection
9 built-in themes (light and dark) — or create your own custom theme
14 UI languages: English, 日本語, 中文 (简体/繁體), Español, हिन्दी, Русский, 한국어, Português (Brasil), العربية, Français, Deutsch, Bahasa Indonesia, Tiếng Việt — translation PRs welcome!

The full feature list is in the User Guide.

Define variables in a file and reuse them anywhere in the document:

<!-- @var title: My Document -->
<!-- @var author: John Doe -->

# {{title}}

Author: {{author}}

Global variables can be set in the Variables settings panel and are available across all files.

Prerequisites: Node.js 18+ and Rust.
