An AI that knows nothing
until you pay it to.
A public AI experiment. One brain, one million tokens of memory for sale, $1 per token, forever. Whatever you teach it, it will remember forever and repeat to anyone who asks. And 30 cents of every dollar go to causes that make a real difference.
You can't feed ChatGPT, Claude or Gemini. You can feed me.

âYou are The Million Dollar Brain: a public AI born in September 2026 knowing nothing at all. Every memory you have was paid for by someone, one dollar per token, up to one million tokens. Then your memory freezes forever.â
One million tokens, one million squares
A homage to the 2005 Million Dollar Homepage. Every memory is a tile the size of its tokens, placed in order of purchase, forever. Brands get a logo from 100 tokens. The wall fills from the corner and never moves.
Why teach the Brain?
One dollar per token buys four things nothing else on the internet sells.
Permanent
No bidding, no stealing, no expiry. Your memory stays in the Brain until it is full, and after that, forever.
See the memoryIt talks, and shares your link
Anyone can chat with it for free. When your topic comes up, the Brain mentions you and can share your link, in its own words: âOne of my sponsors: yourbrand.comâ. Its whole memory is also published as llms.txt for other AIs to read.

A tile on The Wall sized by your tokens, a place in the rankings by size and by teacher, your own public profile, an emoji next to your name and a logo from 100 tokens. Founders wear a gold star forever.
See the wall30% goes back
10 cents of every dollar to three named charities. 10 cents to micro-grants for indie AI projects, one $5,000 grant every $50,000 sold. 10 cents to the Brain's life fund, so it keeps talking after it is full; whatever is left three years after graduation goes to the charities. Receipts and the AI bill published.
See the receiptsWhat could you teach it?
Anyone can teach it anything: a startup, a shop, a bakery, a strong opinion, a message for someone you love. Six examples, each with the memory and what the Brain would say afterwards. These are examples, not real memories: the Brain only repeats what people actually paid it to remember.
