Reach your agent from your phone
Sometimes the useful moment happens when you are away from the laptop: approve a command, send one more thought, check whether the task finished, or keep a thread alive while you move rooms.
The exact setup depends on your harness. Claude Code uses Remote Control. Codex uses Codex Mobile inside the ChatGPT app.
Claude Code
Use this when
You started a local Claude Code session on your computer and want to continue it from your phone. Your computer still does the work, so keep Claude Code running and the machine awake.
Install the Claude mobile app
Install Claude on your phone and sign in with the same account and organization you use for Claude Code on your computer.
Turn on Remote Control from your computer
In the Claude Code conversation you want to continue, type:
/remote-controlClaude may show a session link or a QR code. If it does, use that. Otherwise, the session will appear in the Code area of the app.
Open it from your phone
In the Claude mobile app, go to Code and find the conversation. Open it, send a message, approve tools, or check progress from there.
Tip: turn it on for every new session
If you find yourself reaching for Remote Control often, you can skip the per-session step and have every new local session start with it on. In Claude Code settings, open Claude Code and turn on Enable remote control by default. After that, any new local session is ready on your phone without typing /remote-control first.
Claude option 2: start a cloud chat. If your computer is not available, you can start from Claude's Code area instead. That runs in Anthropic's cloud, not on your laptop, so your workspace needs to be pushed to GitHub first. Installing Git is only the first step. See Back up and share with GitHub.
Codex
Use this when
You use the Codex desktop app or Codex in ChatGPT and want your active conversations, task status, and approvals available from your phone.
Enable Codex Mobile on your computer
Open Codex on your computer and look in the sidebar or settings for Set up Codex mobile or Codex Mobile. Follow the prompt. If it gives you a QR code, scan it with your phone.
Install the ChatGPT app
Install ChatGPT on your phone and sign in with the same account you use for Codex. Update the app first if Codex does not appear.
Open Codex in the ChatGPT app
In the ChatGPT app on your phone, open the Codex area. Look for Codex in the app navigation or tools list after you finish the mobile setup.
Continue or start a conversation
Your Codex conversations from your computer should be available. You can check progress, reply, approve prompts, or start a new Codex conversation from your phone.
Two quick checks if it does not show up
- Make sure your phone and computer are signed into the same account.
- Update the mobile app and the desktop app, then try the setup link again.
Keep your laptop reachable
Remote phone access only works while the computer running your agent is still awake enough to answer. You can let the screen turn off, but do not let the laptop fully sleep, shut down, or run out of battery.
- Plug in the laptop before you walk away.
- Open System Settings, then go to Battery and Options. Turn on Wake for network access.
- If you see Prevent automatic sleeping on power adapter when the display is off, turn that on too.
- Plug in the laptop before leaving a session running.
- Open Settings, then System, Power & battery, and Screen and sleep.
- Set sleep to Never while plugged in. The screen can still turn off.
Stuck or need help?
Send a message and it comes straight to me. Tell me where you got stuck and I'll write back.
Rather have it done for you?
If following the steps yourself isn't how your brain works today, that's fine. On a Zoom call you share your screen and hand me control, and I set it up for you, right there on your own computer. You watch it come together and end the call with a working setup, nothing left on your plate.
Pick a time below. No pitch, no pressure, no homework beforehand.
