iPhone
A native app with notifications you can answer. Keys in the Secure Enclave.
For Claude Code and Codex
Answer your agents from anywhere.
Your coding agent stops to ask "may I run this?" and waits. SI Everywhere puts that question on your phone, your Lock Screen, any browser or your glasses, with the exact command, so you can allow it, deny it or tell the agent what to do next. Then get back to your walk.
Works with the tools you already run, on your own computers. End-to-end encrypted.

About five minutes
Three steps, then it just works
No configuration files, no accounts per tool. One small agent on each computer, one command to turn on answering, and a code to add each phone or pair of glasses.

1
Install the agent
Sign in with your SI Somewhere account, make a machine key in its Setup, and paste the two lines it shows into a terminal on each computer you code on. Already use SI Somewhere? You have it.
curl -fsSL … /install.sh | sh -
2
Turn on answering
Run one command. It shows a link and a QR code: open it on your phone or in your browser, check the short key matches, and type y at the computer.

Add your devices
Open SI Everywhere on your iPhone or glasses. It shows an 8-letter code; enter it in Setup on a device you've already added. That's it: questions start arriving.
Add a device: KXQ4-7M2P
Every step, with what you'll see: the setup guide.
What you can do from anywhere
Everything your agent would ask you at the keyboard, with the same answers you'd give there.
See exactly what it wants
The full command or the file it wants to change, before you decide. Not a summary: the real thing.
Allow, once or for good
Allow once, for the rest of the session, or always (Claude Code adds the rule to your project, as if you'd chosen it at the keyboard).
Deny with a note
"Not that file, use the staging config." Your note goes to the agent as the reason, so it changes course instead of asking again.
Reply to any session
Tell an agent what to do next, even one whose window you closed: SI Everywhere resumes it in the background.
From the Lock Screen
The iPhone app puts the command on the notification itself, with Allow and Deny. Answer without unlocking or opening anything.
By voice, on glasses
On Rokid Glasses: a chime, the question read aloud, a tap to allow. Speak a reply, hear it read back, tap to send.
On whatever is in front of you
Any browser
app.sieverywhere.cc on a laptop, a tablet or a phone, with alerts when an agent needs you.
Rokid Glasses
The question on the green HUD and read aloud. Swipe to choose, tap to answer, speak to reply.
Only your devices can read it
Answering for an agent is power, so SI Everywhere is built so that nobody else can do it, including us.
End-to-end encrypted
Questions, answers and replies are sealed on your computer and opened on your device. The relay in between passes along what it can't read.
Every device proves itself
A device's code is made from its own keys, and the first one is confirmed at the computer's keyboard. A stranger can't slip one in.
Signed both ways
Your devices show only questions your computers signed, and your computers accept only answers your devices signed.
Off until you turn it on
Each computer decides for itself (sisomewhere actions on), and off stops it at once. Remove a device in Setup and every computer stops listening to it.
Nothing times out
A question waits as long as it takes. At the keyboard? It's still asked there too, and whichever answer comes first wins.
Your logins stay put
No tool's login ever leaves your computer. Approvals run there, exactly as if you'd said yes at the keyboard.
What's stored and where: the privacy page.
$5 a month
One subscription covers all your computers and devices. It includes everything in SI Somewhere, the free viewer (every session and plan limit, live), so you only need this one app. SI Everywhere is in early access: ask to join.

Questions
Do I need to change how I use Claude Code or Codex?
No. Keep working the way you do. The agent hooks into each tool's own permission events; when you're at the keyboard you answer there as always, and when you're not, your devices can.
What happens if I answer at the keyboard and on my phone?
The first answer wins and the other side is told: the phone's question closes and says "answered at the keyboard."
Does it work with the Codex app, not just the command line?
Yes, both, since they share Codex's hooks. Replies reach Codex app chats too.
What if my computer is asleep or offline?
Your answer is kept and delivered when it reconnects. Questions only exist while the agent that asked is running, so nothing happens behind your back.
Can SI Everywhere read my code or commands?
No. The relay sees which computer and session a sealed message is for and when, not what's in it. Session names and states come from SI Somewhere's telemetry, as described on the privacy page.
Who's responsible for what an agent does after I allow it?
You are, exactly as at the keyboard. SI Everywhere shows you what's being asked and carries your answer; it never answers for you.
