Which AI agents and coding tools does Remarc work with?

Remarc integrates with Claude Code, Codex, OMP, and Cursor through plugins. Claude Desktop or another MCP client can connect manually. Every supported client gets the same context and MCP tools for reading comments, managing sessions, and resolving work.

Does my feedback data leave my computer?

No. Comments and screenshots stay on your Mac unless you hand them to an agent or send them through a webhook you configured. There are no accounts or telemetry.

What macOS version is required?

Remarc requires macOS 14.0 (Sonoma) or later. Voice recording and transcription features are available on macOS 26 or later.

Remarc: feedback tool keeps context with AI coding agents

Send on LINE

3 Key Points

What happened
Remarc, a macOS app, lets users comment on text, screenshots, or web elements and attach those comments with full context to AI coding agents like Claude, Cursor, and others via integrations.
Why it matters
AI agents currently lose context when users describe feedback verbally or in separate prompts. Remarc preserves the original selection, screenshot, or web element data with each comment, so agents can act on what the user actually saw instead of a paraphrase—reducing back-and-forth and manual context rebuilding.
What to watch
The app runs locally on macOS 14.0 or later with no accounts or telemetry; data stays on your Mac unless you send it to an agent or export it. It is free and open-source under MIT license, with a companion Chrome extension for capturing web context.

Context & Analysis

Remarc addresses a real friction point in AI-assisted coding: when a developer spots something that needs fixing, they must either describe it in text (losing visual context), take a screenshot and explain it separately, or copy-paste code fragments—all of which require the AI agent to reconstruct the developer's understanding from scratch. By bundling the original artifact (selected text, screenshot, web element) with the human feedback as a structured comment, Remarc lets agents work directly from what the developer saw, not from a lossy description.

The tool's design philosophy—local storage, no accounts, privacy by default—reflects a deliberate choice to make it a thin layer between the developer and their agent rather than a centralized service. The support for multiple input methods (text selection, screenshots with annotation tools, web element capture via Chrome extension, and voice transcription on macOS 26+) recognizes that different feedback situations call for different media. The integration with the Model Context Protocol (MCP) and agent plugin systems (Claude Code, Cursor, Codex, OMP) ensures that the context Remarc captures can be read by whatever agent the developer is using without lock-in.
