Heard is a macOS voice layer for coding agents, turning agent activity into concise spoken updates. It integrates with Claude Code, Codex, and other AI coding assistants, providing real-time narration of progress, decisions, failures, and completed work. Users can download the app, connect agents, and customize listening modes such as Co-pilot, Companion, and Focus. The platform offers free and paid plans, with pricing details, and maintains open-source components on GitHub. It emphasizes privacy, with data processed locally unless optional hosted services are enabled.
