Psst

A tap, not a text.

Your friend is mid-match and you want to know if they're up for a round. A text means they alt-tab out of the game, and a voice ping means everyone hears it. Psst is the third way: pick a line on your Stream Deck, and it lands on theirs. They answer with one press — and neither of you stops what you were doing.

Two decks, one tap

Ben's Stream Deck on the left, Mike's on the right — and both are yours. Every key here is drawn by the plugin's own code, the way it draws them on the hardware, fifteen frames a second. Turn the sound on to hear what each of them hears.

Ben and Mike

Fifteen seconds, from “Play a round?” to Mike's deck stepping back into his game. With sound — Ben's deck on the left, Mike's on the right.

One key on the profile you already use

The Psst key sits among your game keys. Quiet, it shows the mark and a dot in your status colour. When something arrives it shows who sent it, how many are waiting, and pulses three rings with a soft chime — Busy gets one ring and a softer sound, DND none.

Tap it and your deck becomes the conversation, with the answers already on the keys. Hold it to mark everything read without answering.

When several arrive at once

The Psst key doesn't cycle between people. It shows who wrote last, and its badge counts everything unread, from everyone.

Tap the Psst key: you land in the newest conversation, with the answers ready.

Hold the Psst key to mark everything read at once, without answering.

Several from the same friend stack up in their thread, newest at the bottom; bigger decks show more of them at once. A burst chimes once, not once per message, and muted friends count on the badge but never pulse or chime.

On a Neo, it's on the Infobar

The Stream Deck Neo has a small screen under its keys: the Infobar. Put the Psst Infobar action there and a waiting message shows on it — who wrote, when, and the line itself — without switching to the Psst profile or opening anything.

You choose, for each Infobar you place, what it shows while something is waiting: the message, only who sent it, or nothing but a count. And what it shows the rest of the time: the clock and date it showed before, your crew, or your status. It can't be pressed — you still answer from the Psst key — and it goes quiet once you've read.

Stream Deck Neo, with the Stream Deck app 7.6 or newer. Other decks have no Infobar and work as before.

Your deck becomes the conversation

A Psst profile takes over every key on your deck while you talk — six on a Mini, eight on a Neo or a +, fifteen on an MK.2, thirty-two on an XL — then hands your deck back. More keys, more friends and messages on one page. Bubbles span keys, the way they would span a phone screen; your messages are cobalt, theirs are paper.

Your friends — with their status, and yours — Your friendswith their status, and yours

Your messages — one tap sends — Your messagesone tap sends

It goes back on its own

If you came in through the Psst key, your deck returns to where you were three seconds after you answer — a ring on the Deck key counts it down, and it waits a moment longer if something new arrives. Answering a friend costs one press and a glance, and your game profile is back before you've looked away from the screen.

Friends, not followers

There is no sign-up. On first start Psst makes a key pair on your machine, and its fingerprint becomes your ID. Share it however you share things — a chat, a party, a sticky note — and paste your friend's into the settings.

Messages only flow when both of you have added each other. Anyone else is dropped: first by the relay, then again by the plugin. There is no request inbox to fill with spam, and removing someone is how you block them.

Your ID looks like this

Nothing in between

Psst passes messages between friends, so it should know as little as it can — and keep even less.

No account: No email, no password, no profile. Your identity is a key pair that never leaves your Stream Deck settings, and your friends list and messages live there too.
A relay that keeps nothing: The service that connects you holds live connections and the friend list each deck sent it, in memory, and nothing else: no database, no message history, no queue and no log. When a friend is offline, your message waits on your own deck — for up to half an hour — and goes when they're back.
Keys that can't be borrowed: Every connection proves it holds the key behind its ID. The first key seen for a friend is remembered; if their ID ever turns up under a different one, Psst refuses it and tells you.
Nothing beside it: No helper app to install, no Accessibility, Screen Recording, camera or microphone permission. Sounds are played by the audio tools your system already has. Psst is the plugin and one secure connection.

Plain words, on purpose

Messages travel over an encrypted connection and are forgotten the moment they are passed on — but they are not end-to-end encrypted. Psst is for “Play a round?”, not for secrets: short lines you would say across a room.

Requirements

Stream Deck app: 7.6 or newer
Devices: Mini, Neo, MK.2, XL, +, + XL and Galleon 100 SD — with a Psst profile for each, and the Infobar on a Neo
Platforms: macOS 12+ and Windows 10+
Keys needed: One for the Psst key; the profile brings its own
Internet: Yes — one secure connection to the relay
Your friends: Each of them needs their own copy

What it doesn't do

It never shows anything on your screen, never reads a game or a chat, and never types for you. It keeps no history on any server, has no analytics, and knows nothing about you but the ID you chose to share.

Version

v1.2.0

Two more Stream Decks: Psst now comes with a profile for the Stream Deck + XL and for Corsair's Galleon 100 SD, and fills every key of either.
