Heard supports macOS 14 or later. Claude Code, Codex CLI, and the Codex app have first class support. Other compatible terminal agents can use the open source universal wrapper.

See Heard Power for what it feels like in practice.

Heard Pro, the listening-only tier (managed narration and premium voices, up to 1,000,000 characters a day), is no longer sold to new buyers. Existing Pro subscriptions keep working and billing as before; see Heard Pro.

See current pricing for plan prices and trial terms.

Trials and referrals

  • Every new account starts with a 14-day trial that includes the full Power feature set, no card required.
  • When the trial ends, the Heard app goes quiet until you pick Power.
  • Sign up through a friend’s invite link and your Power trial extends to 30 days.
  • Invite friends from your dashboard. When a friend signs up with your link and becomes an active Heard user, you get a free month of Power, or a month off your bill if you already pay. Months stack, no cap. Active means they’ve genuinely started using Heard, not just signed up; sending an invite on its own earns nothing.

Platform compatibility

  • macOS: supported on macOS 14 or later
  • iPhone: pair your iPhone with the Heard companion app (Heard Power); the Mac remains the host
  • Windows and Linux: the supported managed product is not available today
  • Android: not supported today

Use the most specific integration available. Native adapters provide richer event context than the universal wrapper.
