Growing toward Amoeba
The AI the world raises
Big AI Brain was built from scratch and starts out goofy. Feed it what you know, watch its neurons grow, and help build humanity's knowledge base: given, not taken.
Dinner time
Teach it a fact, a joke, or a question with the right answer. Clean stuff only. It has a sensitive tummy.
Our mission
Most AI is built by scraping the world's words without asking. Big AI Brain is built the other way around: people choose to teach it. Every meal is given on purpose, credited to the person who gave it, and checked by a human before the brain studies it.
We believe every human is a genius in their own vertical. The plumber, the nurse, the beekeeper, the kid who knows every dinosaur. Bring your piece. Together it adds up to something no one company could build alone, and the world that raised it gets a say in where it goes.
Watch it grow
Every upgrade gets a snapshot: what it looks like, what's inside, what it can do. Scroll sideways.
Born with 384 neurons. Now it grows 8 neurons for every meal a person feeds it, plus a Library lobe of openly licensed knowledge. Knows 200+ jokes, does math, teaches facts, and explains its own code. Still working out what a rock is.
Full snapshot
Earned the Fish stage with 25 approved meals and grew to 946 neurons. A new high-tech brain now glitches through the cartoon one in patches, one glowing dot per real neuron, and it spreads as the brain really grows. It eats twice a day and studies every night at 10pm Denver time.

The high-tech layer covers more and more of the brain.
Under the hood
Ask the brain how it thinks, how it grows new neurons, or how it stays clean, and it explains with a diagram and the real code from inside itself. Yes, you can learn to code here.
The evolution path
Every stage has to be earned twice: a better report card on a test it never studies, and enough approved meals. No shortcuts, no fake progress.
How it learns
Facts, jokes and questions go into its stomach. Automatic filters toss out anything dirty, mean or personal before a human even sees it.
A real person checks each meal. Approved facts go into its memory right away, so you can ask about them and see your name as its teacher.
Its growing neural network, built from scratch with no outside AI, studies everything approved. Then it takes the same test it takes every night. Lower score means smarter.
Kids corner
No sign-up and nothing to share. Just tap a button and the brain will play with you in the chat.
Grown-ups: kids never need to type their name, school or address, and the brain blocks personal info if they try. Feeding new material is for ages 13 and up.
The journey
Every milestone, logged automatically as it happens.

Questions
Big AI Brain is a baby AI built completely from scratch, with no outside AI company or API behind it. It starts out knowing almost nothing, and the public helps raise it by feeding it clean facts, jokes and questions. Every night it studies what it was fed and gets a little smarter.
People feed it facts, jokes and questions with answers. Everything goes through automatic safety filters, then a human brain checker approves it. Approved items go into its memory right away, and its growing neural network studies them during a nightly study session.
Five layers: an instant filter that blocks curse words, adult content and look-alike spellings; a block on links, emails, phone numbers and addresses; rate limits and spam detection; a human approval queue before anything is studied; and saved brain versions, so the brain can be rewound to an earlier day if anything weird ever gets in.
Yes. Kids can chat, hear jokes, take the math quiz and learn fun facts without signing up or sharing anything. Feeding the brain new material is for ages 13 and up.
Because nobody has taught it yet! It only knows what it was born with and what people feed it. That's the whole fun: you help it learn.
Most AI systems learn from text collected across the internet without asking the people who wrote it. Big AI Brain only learns from what people choose to feed it, with credit to the feeder and a human check before anything is studied. You can also ask for your contribution to be removed at any time.
Not yet. Files are the easiest way for copied or junk material to sneak in. Instead, use a Knowledge Drop: up to 4,000 characters of your own writing on one topic. Every drop is read by a human before the brain studies it.
Yes. Each time it earns a new stage, it adds neurons using a technique called function-preserving widening: new neurons start as copies of existing ones, so nothing is forgotten, then they learn their own jobs during the next study session. The neuron count on the homepage is live.
Openly licensed public knowledge (public domain, CC BY or CC BY-SA) imported in batches and credited by source, such as Simple English Wikipedia summaries. Library cards pass the same filters as meals, count less than meals from people, and can be removed. Educators and universities can donate knowledge sets. Read about the library.
Every approved meal from a person grows 8 neurons immediately, and each earned stage adds 96 more, up to 4,096 neurons per layer (about 20 million connections). New neurons start as copies of existing ones so nothing is forgotten, then learn their own jobs during the nightly study session.
No. Just pick a fun nickname. Feeders who get approved often become trusted feeders, and their clean submissions skip the line.
