See it in Action

Not a screen viewer.
A remote for your AI.

Live session, low latency, and a UI optimized for one thing: sending the next prompt to a Mac-side coding agent without breaking your flow.

Watch the agent. Steer the agent.
Live Control

Watch the agent. Steer the agent.

See what Claude Code, Cursor, or Codex is doing in real time. Correct course with a gesture, drop a new prompt by voice, or fire a saved shortcut — all without going back to the desk.

Pick up where your agent left off.
Repeat Sessions

Pick up where your agent left off.

After the first QR scan, no scanning, no re-login — ever. Pick up your phone, one tap, pick up where the agent left off.

Every control sharpened for prompts.
Tuned for Prompting

Every control sharpened for prompts.

Voice trigger words, gesture sensitivity, cursor size, shortcut panels — tune the remote until sending the next instruction feels effortless.

Light & Dark

Two themes.
Pick the one that fits your night.

Nivlok ships with hand-tuned light and dark themes. Switch anytime in Settings — the whole app follows.

Built for Apple

Native under the hood.
So the UX can stay obsessed.

Swift and SwiftUI on both sides. Video streams over WebRTC (H.264); input rides encrypted WebRTC data channels in the same session. Sessions stay between your devices on the same LAN or the same Tailscale tailnet.

Swift & SwiftUI

Both apps written fully in Swift. Native performance so the remote feels instant.

WebRTC

Nivlok gives you a live view and manual controls for the apps and tools on your Mac.

Certificate Pinning

TLS with pinned certificates — every reconnect verifies it's really your Mac.

Tailscale Ready

Same tailnet, any location. Keep nudging your agent from home, café, or across the office.

WebRTC Data Channels

Touch, gestures, and keystrokes travel on dedicated low-latency data channels — same encrypted session as the video.

QR Pairing

Pair on the same network. The QR carries host address, one-time code, and certificate pin.

Use Cases

Stay in the loop,
wherever you are.

The agent runs on your Mac. Your phone is how you keep it pointed in the right direction — from the couch, the kitchen, or a café.

Couch Prompt

Send the next prompt from the couch.

Claude Code is halfway through a refactor and you spot the wrong path. Open Saved Macs, type one correction, keep watching. No getting up.

Watch long runs

Babysit long agent runs on your phone.

Leave your agent chewing through a test run, a build, or a multi-step task. Check in on iPhone, retry or redirect the moment it fails.

Voice prompt

Speak the prompt when typing is too slow.

Hands full, away from the keyboard, or just faster by voice — dictate the next instruction straight into your agent's prompt.

Remote vibe

Keep vibe coding across locations.

Put iPhone and Mac on the same Tailscale tailnet. Saved Macs reconnects from home, travel, or the office — your agent never feels far away.

Security Model

FAQ

Which AI coding agents does this work with?

Any agent that runs as an app or terminal UI on your Mac — Claude Code, Cursor, Codex, Copilot, Aider, and others. Nivlok is a remote for the Mac itself, so whatever prompt UI your agent exposes becomes reachable from your iPhone.

Does it work from outside my home network?

Yes, via Tailscale. Join both iPhone and Mac to the same tailnet and you can keep prompting your agent from anywhere — home, café, the office — as if you were on the same local network. The first pairing still needs the same local network. After that, Saved Macs reconnects automatically over Tailscale. Generic corporate VPNs are not officially supported.

What happens after initial setup?

After the first QR scan, your Mac is saved. Next time you pick up the phone, one tap and you're back inside the same agent session — no scanning, no re-login.

How is it secured?

Pair on the same network. The QR carries host address, one-time code, and certificate pin. Saved Macs uses the pinned certificate. Every session verifies it's really your Mac before anything streams. Nivlok runs no screen relay. Tailscale can relay encrypted traffic; speech recognition and tools on your Mac follow their providers' data policies.

What macOS permissions are needed?

Screen Recording (to stream the agent's screen) and Accessibility (to forward your prompts and gestures).

How do I set up Tailscale?

Create a free account at tailscale.com, install Tailscale on both Mac and iPhone, and sign in with the same account. Once both devices are on the same tailnet, complete the initial pairing (local network required the first time). After that, Saved Macs handles Tailscale-based reconnection automatically. The free plan is enough for solo developers.
