Bit Juggling is a desktop Markdown editor built around two ideas.
The first is that notes should stay yours. A vault is nothing but a folder of
.md files on disk — no database, no proprietary format, no lock-in — so the
same notes open just as well in Obsidian, in Vim, or straight out of a Git
repository.
The second is that a writing tool should be able to read what you wrote. Reevik
ships with an editorial agent powered by Claude, running either through the
local claude CLI or your own Anthropic API key. Open a note and it reviews the
draft: a quality score across clarity, structure, grammar and tone, a one-line
assessment, and a list of concrete edits you apply one at a time by clicking
them. It proposes local changes only — it never rewrites the document behind
your back.
Live Preview
Markdown renders as you type, and the raw syntax reveals itself only on the line
under the cursor. ⌘/ drops to source when you want it.
Notes can hold live Vega-Lite charts, Mermaid diagrams, LaTeX via KaTeX, resizable images, GFM tables and highlighted code — all rendered in place rather than behind a preview pane.
The editorial agent
Alongside the review there’s rephrase-a-selection (⌘⇧R) and find-references
(⌘⇧F), which genuinely searches the web and hands back citations you can
insert. API keys live in the macOS Keychain; the files never leave your disk.
Built with
Rust and TypeScript on Tauri, which keeps the binary small and the memory footprint closer to a native app than to a bundled browser. Builds are for Apple Silicon.
Source, releases and changelog are on GitHub, free under Apache 2.0.
