Hearth puts AI agents to work for you at home. Run agents on your Mac or Linux machine to handle the tasks you never get to — and stay in control from your phone. When an agent is about to do something sensitive, it asks first. You get a notification on your iPhone and tap Allow or Deny. Tap "Always Allow" on actions you're comfortable with and Hearth remembers. Over time, your agents get more autonomous for the things you trust them with, and interruptions become rare. FREE FEATURES • Approve from anywhere — agents ask before anything important; handle requests in seconds from your phone • Talk to your agents — send instructions to any running agent mid-task from your phone, no laptop required • Smart rules — tap "Always Allow" once; Hearth handles it automatically from then on • See everything — the Transcript tab shows exactly what every agent is doing, step by step, in real time • Multiple agents — run separate agents with distinct rules and activity histories • Rich previews — see exactly what the agent wants to do before you approve • Pull the Plug — stop any agent instantly with one tap HEARTH PRO • Push notifications — get notified when an agent needs you, even when the app is closed • Time Sensitive alerts — break through Focus modes • Voice input — on-device speech-to-text powered by WhisperKit (iPhone 12+) • Temporary grants — time-limited auto-approve rules that expire automatically Your agents run on your own machine. Hearth relays requests to your phone — nothing executes without your rules.
