MindGrid · stage mentalism tool · one-time, no subscription

They just chose it. You already knew.

The kind of magic David Copperfield used to pull on TV viewers — now every person in the venue lives it on their own phone. A 3-second QR scan, no app to install. One tablet gathers hundreds of people into a single prediction.

Why we made it

Copperfield did it through a screen. We wanted the whole room in on it.

The magic David Copperfield pulled on TV lived on the far side of a screen — the audience watched it happen to someone else. We wanted the opposite: everyone in the venue, on their own phone, taking part in the same moment together on one stage. That's the reason we built MindGrid.

01 — JOIN

One QR on the big screen. The whole room is in within seconds — nothing to install.

02 — PLAY

Words, images, emoji. Build the 4×4 or 3×3 deck your routine actually uses.

03 — FINISH

One image on stage. Every choice converges into the ending they remember.

Made for the room you actually work

  • ✓Stage & theater mentalists — turn hundreds of strangers into one connected act.
  • ✓Corporate & club performers — high-tech participation that reads to the back row.
  • ✓Parlor & close-up workers — the same impossible finish, scaled to a living room.
  • ✓MCs & speakers — instant audience interaction, zero setup on their side.

Why it lands where other apps don't

  • ✓No install for the audience — the moment starts in seconds, not after a download.
  • ✓The whole room is the deck — not one spectator on stage; every phone is a live cell you drive.
  • ✓Built for real venues — big-screen mirroring, stage branding, your name on the wall.
  • ✓Free choice, fixed ending — they pick whatever they want across a 4×4 grid, but the destination is always the one square you set beforehand.
  • ✓Bring your own deck — upload your own words, images and emoji into any cell of the grid.
  • ✓Made for collabs — drop a magic brand's props onto the grid and the whole room plays with them.

What you can do

Four things MindGrid does that a card trick can't — scroll through each one.

Performer console — QR to join and a live audience counter
01

The whole room joins in seconds

One QR on the big screen and hundreds of phones are in before you've finished a sentence — no app, no sign-up. Your console counts them live as they connect, so you always know exactly how big the room is.

  • ✓Audience joins in-browser from a QR — nothing to install
  • ✓A live counter fills your console as phones connect
  • ✓One tablet gathers up to 1,000 people into a single act
02

Bring your own deck

Load the 4×4 or 3×3 grid with your own words, images and emoji — the deck your routine actually uses. They choose freely across it, in front of everyone, and still the room lands on the one square you set first.

  • ✓Any cell: your own words, images or emoji
  • ✓Free choice, fixed destination — set beforehand
  • ✓Collab-ready — drop a magic brand's props onto the grid

Audience phone — pick one from the grid
03

Everyone plays from their own phone

Not one volunteer on stage — every spectator chooses on their own screen, in their own hand, and the moment happens to all of them at once. Cue the whole room one cell at a time and every phone moves together on the same beat.

  • ✓Each person picks on their own phone
  • ✓Guided moves — up, down, left, right — in sync
  • ✓The back row lives it exactly like the front
04

Your name on the wall — and a tap to your Instagram

Pin your logo, show name and a tagline to the bottom of every audience phone — it rides under the grid the whole show. When the finale lands, every phone can jump straight to your Instagram, so the room that just watched you follows you before they've left their seats.

  • ✓Your logo or poster + show name on every screen
  • ✓A tagline line for your handle or site
  • ✓Ending link sends the whole room to your Instagram

The performer's console

Your screen is the console — it counts the room, cues your next move, and keeps every hint private. The audience only ever sees a clean, branded screen.

Your console — live counter, secret tap, private cue

  • Private performer cues
    The next move shows on your phone alone — the audience never sees the prompt.
  • Secret tap to advance
    Move the whole room forward with one invisible touch. No buttons they can read.
  • Your brand, front and centre
    Logo, show name and your name on the audience screen — opening and ending wrapped in your brand.

Three steps and the room is your stage

01

Open a show

Start from one tablet; a QR code and share link appear.

02

The audience joins

They scan or open the link on their own phones — no install.

03

Play together

Everyone follows picks and moves on the grid from their own phone — their input arrives live on your control screen.

04

The finale

Every choice converges — your image lands on the room, then scatters into sparks.

Every choice converges into one image

MindGrid's signature. Set the final object to your own image, then bring it to the big screen the instant the room's choices meet — the ending they remember longest.
