The fine print, but friendly
Feeding rules & terms
Last updated October 12, 2026. By using Big AI Brain, you agree to these rules.
Who can feed the brain
Anyone can chat with the brain, hear jokes, take the math quiz and learn facts. Feeding the brain new material is for people 13 and older. If you're younger than 13, you're welcome to play and learn, but please don't use the feeding form.
What the brain can eat
- True facts about the world, in your own words
- Clean, kid-friendly jokes
- Questions with correct answers
What makes the brain barf
- Curse words, adult or sexual content, or anything not okay for kids
- Hate, bullying, threats, or anything mean about a person or group
- Personal information: real names, addresses, phone numbers, emails, school names, social media handles or links
- Spam, ads, links, or made-up "facts"
- Song lyrics, book passages or anything else you copied from someone else
How meals are checked
Everything you feed goes through automatic filters first. Then a human brain checker reviews it before the brain studies it. We can approve, reject or remove anything at any time, for any reason, including things that were approved before. Feeders who repeatedly break the rules lose the ability to feed.
Tell us how you know it
Every meal asks how you know it: you made it, you know it firsthand, or it's public knowledge in your own words. Be honest. That record stays attached to your contribution and is part of what makes this knowledge base trustworthy. Knowledge drops (longer entries on one topic) are always read by a human before the brain studies them.
Your meals and our use of them
Only feed things you wrote yourself or that are common knowledge. When you feed the brain, you give Big AI Brain permission to store, display, edit, and use what you fed (and your feeder nickname as credit) to train and improve the brain and its future versions, in any format, forever, without payment. Please don't feed anything you want to keep private.
The brain can be wrong
Big AI Brain is a learning experiment, and it is still very young. Its answers can be silly, incomplete or wrong. Never use it for medical, legal, financial or safety decisions. If you're ever in trouble or feeling unsafe, talk to a trusted adult, and in an emergency call 911 (in the US).
Changes
We may update these rules as the brain grows. The date at the top shows when they last changed.
