Heard

What is Heard?

Heard is a macOS app that listens to your coding agent's events, understands what matters in context, and turns the useful parts into concise, natural speech. It offers multiple listening modes (Co-pilot, Companion, Focus) and supports multi-agent awareness, allowing you to follow parallel sessions with distinct voices. Heard also includes Heard Power for mobile pairing, enabling you to listen, approve, and reply by voice while away from your Mac. The app is open-source (Apache-2.0) and offers free, Pro, and Power plans.
