The story

It Started With One Question…

BattleBrain started with a simple idea from Hreyansh, aged 7.

He loved asking questions like:

“Which one is faster?”“Which one is stronger?”“Who would win?”

Instead of answering one question at a time, Hreyansh and his dad decided to turn the idea into a game.

And BattleBrain was born.

AI + facts

Curiosity Powered by Technology

How AI helps

BattleBrain uses AI technology to help validate and check some of the facts and comparisons used in the game.

This AI-powered validation uses Anthropic’s Claude platform and API.

Good to know

BattleBrain is designed for fun and general discovery.

  • Animal abilities, vehicle specifications and other statistics can vary by individual, model, source and how they are measured.
  • AI can sometimes make mistakes.
  • So please treat BattleBrain as a fun game, not a scientific or professional reference.
For parents

Kids Should Play. Not Fill In Forms.

No accounts
No names
No personal profiles
No public leaderboards

BattleBrain is designed so children can play without entering their name, email address, phone number, school or other unnecessary personal information.

Game preferences and scores, such as Your Best, may be stored locally on the player’s device.

Like any online service, our hosting and online providers need to process basic technical request information (such as IP address and device type) to deliver the game and keep it secure.

Play for Free

BattleBrain is currently free to play. It started as a fun father-and-son project and we want children and families to enjoy it.

Running BattleBrain involves ongoing costs such as hosting, infrastructure, AI services and platform fees. If BattleBrain grows significantly, we may introduce optional paid features or pricing in the future to help cover the cost of running and improving it. Any future pricing will be clearly communicated before a user is charged.
