The AI is in the room with you
Five game modes. Real-time multiplayer. Our AI as a visible, competing participant. The party game that actually uses AI the way it should be used.
Five Ways to Play
Each mode gives the AI a different role — from undercover agent to rival player to creative opponent.
Human or Machine
AI Role: Undercover Agent
Everyone answers the same prompt. AI sneaks in fake answers. Can you spot the machine?
Countdown Clash
AI Role: Rival Player
Race against AI and friends to answer trivia. Faster answers score more points.
Pulse Check
AI Role: Prediction Engine
Share opinions, then predict how the group voted. AI tries to read the room too.
Quick Draw
AI Role: Creative Opponent
Head-to-head prompt battles. Write the funniest response — the group votes.
Flip It
AI Role: Puzzle Master
AI generates word puzzles in real-time. Buzz in first to solve them and score.
How It Works
Get playing in under 60 seconds. No accounts required for guests.
Create a Room
One person creates a game and shares a 4-letter room code with friends.
Friends Join
Everyone joins on their own phone — no app download required for guests (coming soon).
AI Plays Along
Our AI is a visible player in the room — competing, bluffing, and generating content in real-time.
The AI Difference
Most games hide AI behind the scenes. PartyBrain puts it right in the room — with a name, a score, and a personality.

“Finally a party game where the AI isn't just running things behind the scenes — it's actually IN the game.”
Marcus T.
Beta tester
“The Party Pass is genius. $2 for a whole night of games with 12 people? That's cheaper than a board game.”
