Overview

Remarc is a free, open-source macOS menu bar app that turns scattered feedback into structured work for AI coding agents. Point at anything on your Mac — selected text, a screen region, a web element, or your voice — leave a comment, and your agent reads and resolves it over MCP. Comments carry their source context, move through Open, Handed Off, In Progress and Resolved states, and group into review sessions you can export as Markdown or JSON. Works with Claude Code, Codex, OMP and Cursor; everything stays on-device until you hand it off.

Pricing: Free and open source (MIT)

Minimum macOS: 14.0 (Sonoma)
