OpenAI Codex Heard

Works with OpenAI Codex

Available · Native adapter

Codex CLI and the Codex desktop app both run the Heard hooks, so progress, questions and results are spoken as they happen. For the Codex app, Heard also lists your threads, jumps you to the right one, and can type your reply into its composer. Narration stays asynchronous, so it does not block the agent.

Heard labels this integration as “Native adapter.” That label describes how Heard receives the work rather than treating every tool as if it had the same native connection.

Setup

Set up Heard for Codex

  1. Install Heard

    Download and open Heard on macOS 14 or later.

  2. Connect Codex

    Enable Codex in Heard. In Codex CLI, open the hooks screen and trust the Heard hooks when prompted.

    Open source engine, Codex CLI
    heard install codex-cli
  3. Choose your listening mode

    For the Codex desktop app, keep Heard running: the same Codex hooks report its work, and your threads appear in Heard, ready to jump to or reply into.

    Open source engine, Codex desktop
    heard install codex-app

What you will hear

Narration is a filter, not a transcript

Heard looks for progress, blockers, decisions, failures, and useful results. Routine churn can stay quiet or become part of a later summary, depending on the listening mode you choose.

Hey Parrot opens Claude Code and Codex, then Jarvis turns dense output into one sentence.
  1. Codex CLI progress, questions, test results, and final responses

  2. Codex desktop progress and results, plus threads you can jump to and reply into

  3. Parallel Codex sessions with priority based narration

  4. Voice replies routed to the selected session on Heard Power

Co-pilot gives short signposts while the screen is on. Companion gives a fuller briefing away from the desk. Focus stays quiet until something needs you.

Limits

Know the boundary before you leave the screen

A reliable eyes off workflow starts with an accurate support boundary. Run a short test task, confirm that questions and final results reach Heard, and keep the original tool available for interactions the integration cannot route.

  • Heard runs on macOS today.
  • Trust the Heard hooks once in Codex before your first session.
  • Spoken replies and pairing your iPhone with the companion app require Heard Power.

Questions

Frequently asked questions

Does Heard work with OpenAI Codex?

Codex CLI and the Codex desktop app both run the Heard hooks, so progress, questions and results are spoken as they happen. For the Codex app, Heard also lists your threads, jumps you to the right one, and can type your reply into its composer. Narration stays asynchronous, so it does not block the agent.

What kind of OpenAI Codex support does Heard provide?

The current support level is native adapter. The page above names the exact setup path and limitations so “works with” does not hide the difference between a native adapter, a wrapper, and a terminal host.

Does Heard block OpenAI Codex while it speaks?

No. Heard processes narration asynchronously. The coding agent can continue working while speech is generated and played.

Can I use Heard with several agents at once?

Yes. Heard keeps session context separate, gives attention to blockers and decisions, and can roll lower priority activity into a shorter spoken brief.

Can I talk back to the agent?

Talking back is part of Heard Power: say “Hey Parrot” or hold right ⌘ to dictate a reply, and pair your iPhone with the companion app to answer away from your desk. Availability can depend on the integration path and whether the underlying tool accepts the response through the active session.

What leaves my Mac?

The open source engine can use local Kokoro speech and your own keys. Managed narration can send a compact narration snippet to configured service providers. Heard does not retain source code, terminal output, narration text, or generated audio after a hosted request completes.
