Features

Automatic AI Detectionssss

Sidecar monitors your terminal and automatically activates when it detects Claude Code, Codex, or Gemini CLI. The review panel opens alongside your editor without manual intervention.

Structured Diff View

File changes are displayed with collapsible chunks organized by code scope. Each chunk header shows the relevant function, class, or module name using LSP symbol detection, making it easy to understand the context of changessss.

File Tree with Status Indicators

Modified files appear in a hierarchical tree view with visual status badges:

• A (green) — Added files
• M (yellow) — Modified files
• D (red) — Deleted files

Inline Review Comments

Select single or multiple lines in the diff view to add comments. Comments are collected in the sidebar and can be sent directly to the active AI terminal with one click.

Markdown Preview

For markdown files, toggle between diff view and rendered preview to see documentation changes as they will appear.

Usage

Automatic: Start any supported AI tool in VS Code's integrated terminal. Sidecar opens automatically.
