Feature · Phone screen mirror
A second screen
for your AI assistant.
Mirror mode puts the whole Hidini conversation on your paired phone. The live transcript, the answer as it is written, the code with its colours intact. Hide the overlay entirely and read it off the phone standing next to your Mac.
Your eyes go somewhere natural
An overlay on your own screen is invisible to everyone on the call, but it still sits right next to the camera. Reading it means reading your screen, and a small window in a corner means reading a corner of it.
A phone propped next to the laptop is a place your eyes already go. Stand it beside the keyboard and glancing across at it looks like glancing at notes, because that is what it looks like.
The Mac screen can stay empty
With the conversation on your phone, the overlay has nothing left to do on screen. Hide it with its shortcut and Hidini keeps listening, keeps answering, and keeps feeding your phone.
That leaves you sharing a desktop with nothing on it but the work, which is a simpler thing to explain than a desktop with a window you would rather nobody asked about.
What lands on the phone
The whole conversation, live
Every line the overlay has is on your phone: what the interviewer said, what you said, and the answer being written. It arrives word by word, the same way it does on the Mac.
Code stays code
Fenced blocks keep their syntax colours and their monospaced layout, so a snippet is as readable on the phone as it is in the overlay.
Ask from the phone
There is a box at the bottom. Type a question, send it, and your Mac runs it as if you had typed it into the overlay yourself. The answer streams back into both screens.
It waits when you are reading
When an answer is still being written and there is more below the fold, the chat holds its place instead of scrolling out from under you. A Follow new messages button takes you back down when you are ready.
Clear it in two taps
The bin next to the message box wipes the conversation on both devices. It asks first, because there is no undo.
Switch modes whenever
A dropdown at the top flips between Remote control and Mirror. Move the overlay with a drag, then switch across to read what it says.
Three steps, one dropdown
Pair the phone
Press the phone button in the overlay header and point your camera at the code. The control opens in the phone browser, already connected.
Pick Mirror
Use the dropdown at the top left. The screen swaps from the trackpad to the conversation, and stays on Mirror the next time you connect.
Stand it beside your Mac
Prop the phone next to the laptop, where your eyes fall naturally. Everything the overlay shows is there, at a size you can actually read, angled away from the camera.
The other half of the dropdown is the trackpad. See how the phone remote works.
It goes to your phone and nowhere else
The conversation travels from your Mac to your phone over your own network, on a link that refuses to run over cellular. Nothing about it reaches us, because there is nowhere for it to go: no account, no server in the middle, no record of what was said.
The phone holds the conversation only while it is connected. Disconnect, or close the tab, and the mirror empties. The pairing code is good for one session, so an old photo of the QR code opens nothing later.
Common questions
Does the overlay have to be visible on my Mac?
No, and that is the point. Hide the overlay with its shortcut and the conversation keeps arriving on your phone. Hidini is still listening and still answering, the Mac screen just has nothing on it.
Is the mirror a copy or the same conversation?
The same one. The Mac owns it and the phone shows it, so clearing on the phone clears on the Mac, and a question typed on the phone lands in the same thread as everything else.
Does my screen sharing software see the mirror?
It cannot. The mirror is on a different device. What your Mac shares is unchanged, and the overlay itself stays as invisible as it always was.
Does the conversation go through the internet?
It does not. Your phone reads it from your Mac directly over your local network. There is no server of ours in the middle, Hidini sends nothing about the session anywhere, and the link refuses to run over cellular.
What happens to the mirror when I disconnect?
It empties. The phone keeps nothing after the session ends, so an unlocked phone found later has no conversation on it.
Do I need the app from an app store?
No. Your Mac serves the page itself, so it opens in whatever browser the phone already has. iPhone, Android, or an old tablet on the same Wi-Fi.
