Choosing a plan
Free is the open source narration layer: local voices or your own keys, no microphone. Pro adds managed voices and LLM, premium personas, spoken recaps across sessions and priority setup guidance.
Power adds everything that uses a microphone: “Hey Parrot” voice conversations, hold right ⌘ dictation, Ambient mode, and the iPhone companion for listening live, replying and allowing requests once.
Parrot is Heard’s read-only conversational layer for codebases. Ask about architecture, behavior, and implementation details by voice, then hear a grounded answer back.
Jarvis is in development. You can download Heard today for the current coding agent voice experience while the one click Jarvis build is being prepared.
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.
Hear and answer your coding agents. Start free on macOS.
