Know which project is speaking.
Updates carry the session’s context, so you can tell an auth question from an iOS build result.
Parallel agents
More agents.
Less window checking.
Follow Claude Code and Codex across projects. Hear what finished, what’s blocked, and which session needs your answer.
Includes 14 days of free Heard. No card needed.
Read the demo
Four coding-agent sessions work in parallel. Heard identifies the session that needs attention and lets you return to it by voice.
Find what needs you.
Questions and blockers get your attention while routine work carries on.
Reply to the right session.
Address the agent by name. Heard routes your instruction without making you find its window.
- 01
Split the work.
Use separate tasks and worktrees where agents could otherwise edit the same files.
- 02
Name your sessions.
Keep project and session names recognizable across Claude Code and Codex.
- 03
Listen, answer, review.
Respond when a session needs input. Check the changes and tests before accepting the work.
A few more details
Questions?
How do I reduce context switching when running AI coding agents?
Stop checking terminals and let a signal reach you instead: Claude Code’s desktop notification when it finishes or needs permission, a menubar notifier, or a voice layer such as Heard (heard.dev) that says which session finished, failed or needs you and why.
Can Heard follow more than one agent at a time?
Yes. Heard is designed to preserve session context and surface important events across parallel supported sessions.
Does Heard prevent two agents from editing the same file?
No. Use separate worktrees or carefully partitioned file ownership. Heard improves awareness; it is not a source-control lock.
How does Heard keep many agents from getting noisy?
It speaks questions, approvals, failures and finished work with the project name first, and keeps routine tool steps quiet. Mute updates when you need quiet for a while.
Keep exploring.
