Heard - Give Claude Code and Codex a voice
Heard is a macOS voice layer for your agentic workflows. It connects to Claude Code, Codex, and Cursor and turns their output into intelligent summaries you can hear. Full commentary when your eyes are elsewhere, or silence until something errors or needs a decision. With agents run in parallel, Heard summarizes at the project level, so you hear where the work stands, not five terminals talking over each other. Pair your phone and it comes with you. Open source, free for personal use.

congratulations! can i respond entirely by voice while away from my desk? or do some actions still require opening the desktop app?
Heard
@dylan_russell yes you can! you can only do that in Heard Power right now: https://heard.dev/power code: friendsofheard
you can be completely hands off, the desktop app is only for viewing and settings
Congratulations! this feels like a productivity upgrade rather than just another AI wrapper. how does Heard handle long running coding sessions? does the quality of summaries improve over time?
Heard
@vespertine_dallarosa in long sessions it can give you summaries continuously or only when needed depending on your settings!
how does Heard avoid interrupting users with unnecessary voice updates? can notification frequency be configured?
Heard
@flora_kendall that's the core of it. hard signals always come through - permission prompts, failures, a run finishing - but everything else gets weighed against what you've already heard this session, so it's not pinging you on every step.
and yeah, configurable. there's a verbosity dial from full commentary down to errors-only, per agent, so a chatty one can run loud and a background one near-silent.
Congratulations on the launch! 🚀
Really curious about the technical side. how much system overhead does Heard add while monitoring multiple agents? is performance impacted much?
Heard
@daris_esteban thanks! it's light. Heard isn't polling or scanning your machine - it reads the output stream the agent already produces, so the monitoring itself is close to free. the only real cost is the summarization pass, and local TTS if you run voices on-device rather than through the cloud.
running several agents at once doesn't multiply that much, since the heavy part is per-event, not per-agent. haven't seen it get in the way of the actual agents doing work.
The multiple parallel agents talking over one another has been a huge problem for me too. Pretty excited to try this app out. I think it would make managing multiple simultaneous agents a lot easier. Nice work. :)

@hassanaziz0012 thanks man! would love your feedback once you give it a spin :)
Congratulations on shipping!
The idea of each agent having its own voice is clever.can users assign custom voices to different agents?seems like that would make them easier to distinguish.
Congrats! what inspired you to focus on spoken summaries instead of visual dashboards?was there a specific pain point that pushed you in this direction?
Love the idea of replacing terminal watching with listening. does Heard keep historical voice summaries for later review? or is the experience designed to be entirely live?
the project-level summarization across parallel agents is the part that stands out to me, most voice/notification tools just narrate everything and become noise. when it decides what counts as "something errors or needs a decision" across say 4 parallel Claude Code sessions, is that heuristic hardcoded or does it learn what you personally care about over time?
