Judgment-based narration
Heard listens to coding agent events, decides what matters in context, and turns that into concise spoken updates instead of a raw transcript.
Heard
Heard is a macOS app that turns coding agent activity into spoken updates for developers working in Claude Code or Codex. It supports different listening modes, customizable voices, and a higher-tier mobile pairing flow for hands-free follow-up.
What Heard is
Heard is a macOS app that gives coding agents a voice. It listens to agent activity in tools such as Claude Code and Codex, then turns the useful parts of that activity into spoken updates so you can stay informed without watching the terminal.
The product is aimed at developers who want ambient updates, quieter focus, or hands-free interaction with their agent sessions. Heard offers different listening modes, customizable voices, and a mobile pairing flow in its higher-tier plan for staying in the loop away from the desk.
Core features
Listening modes
Choose among Co-pilot, Companion, and Focus modes to control how much voice you hear, from short signposts to quiet alerts for approvals or blockers.
Multi-agent awareness
The app follows parallel sessions, uses distinct voices per agent, and can compress background activity into digests so multi-agent work stays understandable by ear.
Voice personas and custom voices
Users can pick from personas such as Aria, Friday, Jarvis, and Atlas, or write their own persona in Markdown to shape the voice and tone.
Agent and key integration
Heard can connect to Claude Code or Codex, supports BYOK with ElevenLabs and Anthropic/OpenAI keys on the free plan, and offers a managed setup with cloud sync on Pro.
Mobile listening and voice control
Power adds Heard Mobile, enabling phone pairing so you can listen, approve, redirect, and pause sessions by voice while the Mac session continues.
Common ways people can use Heard
Stay informed while working in the terminal
Use Co-pilot mode for short spoken signposts while you are actively coding and want awareness without constant interruption.
Catch up without watching the screen
Switch to Companion mode when you want fuller briefings for time away from the screen, such as a walk, commute, or kitchen break.
Reduce noise during deep work
Use Focus mode when you only want to be interrupted for approvals, failures, blockers, or other decisions that need attention.
Handle sessions away from the desk
Pair Heard Mobile in the Power flow to listen, approve, or reply to an agent while the session continues on your Mac.
Follow multiple agents at once
Use distinct voices and digests to keep track of multiple parallel agent sessions without losing which session is doing what.
