metedata/Remarc

Download the signed build from remarc.app/download or GitHub Releases, and install the companion Chrome extension for web context.
git clone https://github.com/metedata/Remarc.git && cd Remarc/app
xcodebuild build -workspace Remarc.xcworkspace -scheme Remarc -configuration Debug -derivedDataPath "$(pwd)/DerivedData"

Usage

• •Requires macOS 14.0 (Sonoma) or later; the app updates itself via Sparkle.
• •Comment on selected text, a screen region (with arrows/shapes/blur), a web element via the Chrome extension, or dictate in Crit Mode on macOS 26+.
• •Comments land in sessions; each supported client gets the same MCP tools for reading comments, managing sessions, and resolving work.
• •Comments stay local on your Mac unless handed to an agent or sent through a webhook — no accounts, no telemetry.

Key features

• ✓Text comments pin the exact quote and source app; screenshot comments keep the image with annotations (arrows, shapes, text, counters, blur, pixelation).
• ✓Web element comments capture the page URL, CSS, layout, accessibility data, and React component details.
• ✓Sessions, statuses (Open to Resolved), searchable History, Markdown/JSON export, and webhook events.
• ✓Voice comments and Crit Mode with on-device transcription (Apple Speech, WhisperKit, Parakeet).
• ✓MCP server and agent skill bundled into the app; MIT-licensed source of truth lives in remarc-agent-plugins.

Best for

Mac developers who want to hand their coding agent context-rich, review-style feedback from anywhere on their machine.

Caveats

• ⚠macOS-only (Sonoma 14+); Xcode 26+ needed to build from source.
• ⚠Voice comments / Crit Mode require macOS 26 or later.
• ⚠This repo vendors the built MCP artifact; the MCP server's source of truth is the separate remarc-agent-plugins repository.
• ⚠Name, logo, and app icon are not covered by the MIT license — forks must ship under a different name and icon.
