Your threads. Your controls.
Saved on your host.
Resume Handsfree sessions on phone or desktop, with their history and project context. Pairing doesn’t import every terminal or desktop conversation.
Fork an existing Codex thread.
Browse eligible local tasks and fork one into Handsfree. Context, working directory, model and permissions carry over. Direct takeover of another client’s task is disabled.
Choose model and effort.
Set host defaults for Claude or Codex. Codex lists your runtime’s supported choices. Changes apply next turn; session overrides and inherited fork settings take precedence.
Keep control from your phone.
Inspect transcripts and tool activity. Respond to Codex approval and input cards. Stop speaking and Stop agent are separate controls.
Before you connect.
Setup docsDoes it use my agent account?
Yes. Sign into Claude Code or Codex on the host. Agent access and usage are separate from Handsfree.
RequirementsCan I use it away from home?
Yes. Keep the host running and reachable through Tailscale on both devices. Keep the phone app open, or use an active CarPlay conversation.
Connection setupHow do I use CarPlay?
Install the latest iPhone beta on iOS 26.4+, pair your computer on the phone, then open Handsfree in CarPlay and tap Start conversation. Speak to your agent and hear its replies; your Mac or Linux host does the work. Transcripts and approval cards stay on your phone.
iPhone access & setupWhere does my data go?
Files and session history stay on your host. Your agent sends context to its AI provider. iPhone transcription runs on-device; recognized text goes to the host. Host-generated reply audio returns over the authenticated connection and isn’t saved in session history.
