Tandem

Tandem is a contextual AI companion for Obsidian. It helps you discuss, improve and organize Markdown notes without applying changes automatically.

Features

• Contextual chat from the right sidebar
• /tandem actions and custom actions
• Reviewable note edits and vault organization plans
• Background suggestions after a pause in editing
• Per-change previews, confidence and priority
• Apply, ignore or postpone suggestions
• English by default, French when Obsidian is French
• Configurable local AI CLI

Installation

Copy this repository into .obsidian/plugins/codex-sidebar, then enable Tandem in Obsidian's community plugins settings. The technical plugin id remains unchanged to preserve existing installations.

The default CLI command is codex on macOS/Linux and codex.cmd on Windows. It can be changed in Tandem's settings.

Development

The plugin is intentionally dependency-free. Validate changes with:

node --check main.js

The version is changed only when a release is published.
