I couldn’t remember what my therapist taught me. So I rebuilt it.

The starting point was embarrassingly vague.

A few years ago, a psychologist showed me something that genuinely changed how I operate. She pulled out these diagrams of the brain and walked me through how our nervous system affects our ability to think, create, and function. Fight or flight, sure — I’d heard of that. But she showed me why rest, play, and fun aren’t optional luxuries. They’re how you get your brain back online after stress takes it offline.

It was one of those moments where you go: why did nobody tell me this sooner?

The problem? I couldn’t remember what any of it was called. I remembered the feeling of the diagrams, the general shape of the insight, and the fact that it involved my brain and my nervous system. That was it. No model names. No scientist names. Nothing I could Google with any confidence.

So I did what I do now — I opened a chat with Claude and basically said: “My therapist showed me brain diagrams about stress and why rest matters. I don’t remember the names. Help.”

That was 12:28 PM on a Tuesday.

Within minutes, I had the names.

Claude walked me through the possibilities based on my description. Did I see a ladder? A window? A brain with layers? We narrowed it down through conversation — not through me knowing the right search terms, but through me describing what I remembered seeing.

The frameworks were: the autonomic nervous system ladder (adapted from polyvagal theory), the Window of Tolerance (Dan Siegel), and the neuroscience of stress and prefrontal cortex function (Amy Arnsten’s research at Yale).

Your prefrontal cortex, the part responsible for creativity, planning, strategy, and empathy, goes functionally offline when your nervous system is in a stress state. Rest and safety bring it back.

Then I said: “I want to share this with people.”

Not as a blog post. Not as a caption. As something visual and interactive — the way my therapist shared it with me. Something someone could tap through and actually feel the shift between states.

So we built it. Right there in the chat.

No wireframes. No design brief. No Figma. I described what I wanted — “a standalone graphic, my voice, something I can drop into a conversation” — and we started building. First, three individual graphics, one for each model. Then I said: can we show how all three connect? And we built a unified interactive piece where you tap between nervous system states and watch the ladder, the window, and the brain all update together.

Then — and this is the part I’m most proud of — I asked for a fact check before sharing. Because I’m not a neuroscientist. I’m someone who learned something in therapy and wanted to pass it along accurately.

Turns out the triune brain model (the three-layer brain thing) is considered outdated by modern neuroscience. The insight — that stress impairs your prefrontal cortex — is rock solid, published by researchers at Yale. But the packaging needed to be more precise. So we rewrote the copy to reflect what the science actually supports, credited the right researchers, and added an honest note that one of the frameworks is “clinically useful, still debated in neuroscience.”

Here’s what actually happened in this session.

Let me be specific, because the specifics are the point:

Nobody asked me to build this. I’m not studying neuroscience. I’m not building a therapy app. I just had a thing I learned that helped me, and I wanted a way to share it that was better than trying to explain it over coffee.

The point is not the brain diagram.

I could have built a recipe converter. A decision matrix for choosing between job offers. A visual breakdown of how compound interest works. An interactive map of my neighborhood’s best coffee shops. A tool that helps someone understand their lease agreement.

The point is: I walked into a conversation with a half-formed idea and walked out with a finished, interactive, fact-checked tool.

No code written by me. No design software opened. No research papers pulled up manually. The entire pipeline — ideation, research, visual design, interactivity, fact-checking, accessibility, iteration — happened inside a single chat.

That’s what’s possible right now. Not in some future version of AI. Right now, today, with tools you already have access to.

What I actually want you to take from this.

If you’ve ever learned something that changed how you think — in therapy, in a class, from a book, from a conversation — and you wished you could share it in a way that lands the way it landed for you?

You can build that now.

You don’t need to be a developer. You don’t need to know the right terminology upfront. You don’t even need a clear plan. You need a starting point and a willingness to say “I don’t remember the details, but here’s what I remember feeling.”

AI didn’t replace my therapist. It didn’t replace the experience of sitting in that room and having someone walk me through my own nervous system. What it did was give me a way to carry that knowledge forward — visually, interactively, accurately.

Try it yourself.

The interactive tool is below. Tap through the three states — Safe & Connected, Fight or Flight, and Freeze — and watch how your nervous system, your bandwidth, and your brain are all connected.

And if it helps you the way it helped me? Send it to someone. That’s literally why I built it.
