In-Game AdBrain

Inspiration

In Friends4Payments we are building the NextGen AI Companions for gaming. And we saw in the hackathon a great opportunity to push the Ad Brain Engine using Grok technology

What it does

Our In-Game AdBrain analyses the gameplay conversation between the Gamer and the AI Companion to offer targeted ads without affecting the gaming experience based on the gamer sentiment and habits.

How I built it

We integrated Grok Voice for seameless communication inside of the game, Grok 4.1 fast for the in-game companion brain and a network of agents using Grok 4.1 fast for the Ad brain and A2A merchant capabilities.

Challenges I ran into

Mainly fighting with the Grok Voice documentation

Accomplishments that I'm proud of

Integrating all this tech in a template from the Unity store in just 24h.

What I learned

Grok models interact with gaming related tools in a very fast and accurate way. But Grok outstanded our expectations for the ad campaign generation part.

What's next for In-Game AdBrain

The In-Game AdBrain should keep growing its data knowledge to improve its analytics capabilities and tailor more accurrate offers for the users with integrations like the X API to understand user background.
