Use the system Talk control for the shortest possible path from thought to action.
Push to talk for the AI on your Mac
Your AI is on your Mac. Transponder puts it on your wrist.
Hold Talk on your iPhone or Apple Watch, speak naturally, and hear your Mac assistant answer from anywhere—without opening your laptop or configuring a private network.

Hold Talk to try it
An interaction preview — no microphone is used.
A voice link, not another AI
The intelligence stays where you already put it.
Transponder gives the assistant working on your Mac a dedicated voice channel. It does not replace your tools, your account, or your workflow. It simply lets you reach them when your hands are somewhere else.
How it works
One button. One private channel.
- 01
Hold Talk
Speak from your iPhone or Apple Watch. Release when you are done.
- 02
Your Mac works
Your approved Mac receives the request and hands it to the assistant you already use.
- 03
Hear the answer
The response comes back through the same system voice channel, even when the app is not open.
Use what is already with you
A quiet line back to your Mac.
iPhone
Talk, follow the conversation, and replay a response when you need to hear it again.
Pebble Index
Already wear an Index? Use it as a discreet third-party capture device. It is never required.
Private by architecture
Your assistant is still your assistant.
Transponder’s hosted relay carries end-to-end encrypted audio between devices you approve. Your assistant account and transcription remain on your Mac, and the relay cannot read the conversation it forwards.

Questions, answered
Before you press Talk.
Is Transponder an AI assistant?
No. It is the voice link to an assistant already running on your Mac. Your existing assistant, account, and tools stay in control.
Will the hosted beta require Tailscale?
No. The hosted relay is specifically being built to remove private-network and router configuration from the experience.
Does my Mac need to stay awake?
Yes. Your Mac does the assistant work, so the Companion must be running and the Mac must be available to respond.
Do I need Pebble Index?
No. Transponder works from iPhone and Apple Watch. Index is an optional third-party input for people who already use one.
Where does transcription happen?
On your Mac, through your own workflow. Transponder does not collect a readable transcript on its relay.
