Tether connects your phone to your own computer. Talk to an AI that runs on your PC, with access to your files and projects — from anywhere.
No accounts required to start, no complicated setup. Your phone talks directly to your computer.
The desktop app for Windows, macOS, or Linux. It starts the local AI agent and shows you a pairing code.
Open the mobile app and paste the code. That's it. Pair as many PCs as your plan allows and switch between them in the app.
Create chats with the AI on your computer. Ask for files, reports, commands. Sensitive actions need your approval — right on your phone.
Tether is built the opposite way from cloud services: the intelligence and the data live on your computer, not on our servers.
Chat history lives on your PC; your phone keeps just a cache for instant loading. Our servers never store a single conversation.
All traffic between your phone and your PC is TLS-encrypted. The cloud relay only forwards packets — it doesn't inspect or retain them.
On the same network as your PC, your phone connects to it directly — traffic never leaves your home. The app always shows the active mode: Local or Cloud.
Nobody can connect to your PC without the pairing code generated locally on it. You can regenerate it anytime.
Reads are automatic, but any command or file change asks for your explicit approval — allow once, allow for the session, or deny.
No analytics SDKs in the app. We can't sell your data because we don't collect it.
Start free, upgrade when your PC becomes your favorite coworker. AI usage runs through your own Claude subscription on your PC.
