About:
One brain, one fact, one conversation.
A network of neurons spins, slows down and stops. Then a fact appears, with its source, a label for how strong the evidence is, and an AI you can ask about it.

The problem:
Brain facts spread faster than the studies behind them. They lose their sources and caveats on the way, and some of the most quoted ones are simply myths.
Goal:
Design a calm, one-fact-at-a-time experience where every claim carries its source and evidence status, and an AI helps you go deeper without overstating the science.
My role:
My own concept. Idea, content design of 846 facts, conversation design and AI guardrails, interaction design and the creative coding of the neuron network.

Discover
Popular neuroscience travels fast and loses its caveats on the way. I wanted to slow it down.
/01
The idea
This was my idea: a brain that spins, slows down and stops, and then hands you one fact you can trust and question.
Brain facts are everywhere, in feeds, talks and office posters. Most of them arrive without a source, and many of them are myths. I wanted a small ritual instead of another scroll: one fact at a time, and the space to ask about it.
/02
Myths travel faster than studies
The most quoted brain facts are often the least true. The ten per cent myth and the left and right brain split survive because they are simple, not because they hold up. Even the famous hundred billion neurons was a rounded guess until someone actually counted.
/03
What a fact needs
A fact is not just a sentence. To be useful, each one needs a source, a plain account of how it was found out, what it means and, above all, what to be careful about. That last part is what headlines usually leave out.
Define
Every fact carries its evidence with it, and the AI is held to the same standard.
/01
Evidence, labelled
I wrote and checked 846 facts. Each one has one of three labels, so you can see at a glance how much weight it carries. A third of the deck is openly debated or based on animals and small samples, and I kept those in on purpose: showing uncertainty is part of being honest about science.
/02
Principles
One fact at a time. No feed, no infinite scroll.
A source on every claim. Author, year and journal, linked.
Say where it is unsure. The label and the caution are as visible as the claim.
Never about your brain. It explains research, it does not diagnose.
/03
Guardrails for the AI
The chat runs on a short list of rules that is rebuilt for every fact, so the AI always knows which fact you are reading, its source and its label. It is designed to say I do not know rather than fill the gap.
Develop
From a spinning network to a conversation, in three moments.
/01
A brain made of neurons
The opening is drawn in code. 520 neurons are scattered inside brain-shaped volumes and linked to their nearest neighbours, with signals running along the links. The brain spins for six and a half seconds, slows down and stops, and only then does the fact appear. The wait is short, but it turns a page load into a moment.
/02
The fact window
Every fact opens with Did you know that, typed in letter by letter. The short answer, the label and the source follow, and the details fade in last, so the reading order matches the importance.
/03
Ask anything
Below each fact there is a chat. Three suggested questions are written for that specific fact, so nobody faces an empty box. Answers stream in, can be stopped at any time, and end with a question that keeps the discussion going.
/04
For everyone
Skip jumps straight to the fact.
Reduced motion shows a still brain and the full text at once.
Keyboard first. The fact is a real dialog, Escape closes it and focus stays visible.
Show fact brings the window back after you close it.
Deliver
A live site with 846 facts and an AI that knows when to say it is not sure.
/01
Three facts, three labels
The label is the first thing you see after the claim. Its style changes with the strength of the evidence: outlined, filled or dashed, so the difference reads even without reading the words.
/02
Under the hood
The page is a single Framer code component. The facts live as a JSON file on Vercel, and the chat goes through a small Vercel function, so the AI key never touches Framer. The function only answers known origins, caps the length of the conversation and streams the reply as it is written.
Outcome
/01
What I learned
Designing for trust is mostly content design. The hardest work was not the animation or the chat, but writing 846 facts so that the caveat is as clear as the claim, and teaching the AI to be just as careful.
/02
Next steps
Test with readers whether the labels change how much they trust a fact.
Let readers flag a fact and suggest a better source.
