Spaced-repetition atoms inline — renders Atomus syntax right in your Obsidian notes.
Atomus uses a simple markdown-first syntax for spaced-repetition "atoms". This plugin makes that syntax render beautifully inside Obsidian, so you can write and review from the same app you already use for notes.
| Syntax | What you get |
|---|---|
Question == Answer |
Single-line atom. == becomes a → arrow; question/answer color-coded. |
Question == child lines |
Multi-line atom. == becomes ↓, indented children show as the answer. |
(x) correct ( ) wrong |
Multiple choice. (x) turns into a filled dot, ( ) into an empty one. |
1. first 2. second |
Numbered list answer. |
Text with {{gap}} |
Cloze deletion — renders as a pill. |
Text {{c1::first}} and {{c2::second}} |
Numbered cloze for multiple gaps. |
- [x] done followed by indented lines |
Atoms under a done todo are dimmed + strikethrough. |
The plugin is visual only — your markdown stays plain text. Compatible with Atomus desktop so the same files work in both.
In Obsidian: Settings → Community plugins → Browse → search "Atomus" → Install → Enable.
Download main.js, manifest.json, and styles.css from the latest release, then drop them into <your-vault>/.obsidian/plugins/atomus/. Restart Obsidian and enable the plugin in settings.
npm install
npm run dev # watch mode
npm run build # production build → main.jsSymlink this folder into your test vault:
ln -sfn "$(pwd)" /path/to/your/vault/.obsidian/plugins/atomusThen Cmd+R inside Obsidian to reload the plugin after each build.
Colors come from Obsidian's native theme variables (--text-accent, --text-muted, --color-yellow, --color-green, etc), so the plugin adapts to any theme you're using — Minimal, Things, Atom, California Coast, Shimmering Focus, custom — without extra configuration.
- Works in both Live Preview and Reading Mode.
- Plays nicely with wikilinks
[[...]], headings, standard lists, and todos — we only touch Atomus-specific syntax. - When the cursor is on an atom's line, the raw source is shown so you can edit; move away and the pretty render returns.
