monocle is a terminal UI that runs alongside your AI coding agent. You review diffs in real time as the agent writes code, leave line-level comments, and submit a structured review in one batch. The agent receives your feedback and starts fixing things immediately — like a PR review, but live.

Installation

Install monocle via Homebrew or download a pre-built binary for macOS or Linux.

Quick Start

Register monocle with your agent and start your first review session in minutes.

Agent Setup

Connect monocle to Claude Code, OpenCode, Codex CLI, or Gemini CLI.

Configuration

Customize layouts, diff styles, keybindings, and review formatting.
