Yes. Start with a month of free Heard, with no card needed. For a fully local setup, you can also build the open source engine with your own keys.
Claude Code and Codex CLI are narrated through first-class hooks. Cloud agents such as Grok Bot, Meta Muse, Devin and Manus report by voice through one MCP connector. Cursor, GitHub Copilot CLI, Gemini CLI and other local agents show their sessions and approvals in Heard. It works in any terminal, including Ghostty, Herdr, cmux, iTerm2 and tmux.
Use a first-class integration when one exists because structured agent events are more reliable than generic output. The open source engine adds a heard run wrapper for other compatible command line tools.
Agent runs can take minutes or hours, and checking every tab breaks focus. Heard lets you hear material state changes and return when a decision, failure, or final review needs you.
The Heard engine is open source under Apache 2.0 and can be built with local Kokoro speech or your own provider keys. The downloadable macOS app is the official managed build.
The path depends on the features you choose. Source code, full terminal output, and agent transcripts stay on your Mac unless an enabled feature sends a short text snippet for hosted narration or speech. Local Kokoro speech stays on the Mac.
No. Heard does not sell your data or use private work to train models. Heard does not retain narration text, generated audio, source code, terminal output, or agent transcripts on its servers.
Heard supports macOS 14 or later. On Heard Power you can text, voice-message or call Parrot from your iPhone. Windows and Android are not supported today.
