Installation

Smart Second Brain runs on Obsidian 1.11.4 or newer, on desktop and mobile alike. Search, the Smart Graph and agents all work on both. The one thing to expect on a phone or tablet is that indexing a large vault is noticeably slower.

From community plugins

1. Open Settings → Community plugins in Obsidian.
2. Turn off Restricted mode if it is on.
3. Choose Browse, search for Smart Second Brain, and select Install.
4. Select Enable.

Search and the Smart Graph work immediately, with no configuration and no AI provider. See What works without a provider for what to try first.

Beta releases via BRAT

Pre-release builds are published for testing and can be installed with BRAT. Add s2b-dev/smart-second-brain as a beta plugin.

Caution

On mobile, fully quit and reopen Obsidian after a BRAT update. The app caches plugin code across a plain reload, so the new build may not take effect otherwise.

Manual install

Download the latest release from GitHub releases and extract main.js, manifest.json, and styles.css into:

<your-vault>/.obsidian/plugins/smart-second-brain/

Reload Obsidian, then enable the plugin under Settings → Community plugins.

Building from source

The project uses Bun as its package manager.

git clone https://github.com/s2b-dev/smart-second-brain.git

bun install && bun run build

The production bundle is written to build/prod.
