How I prompt any AI
Most bad AI answers start with a bad prompt. Mine has four parts: context, task, constraints, format. The same four parts work in Muse, ChatGPT, Copilot, or Claude. The tool changes. The thinking does not.
Learning out loud
I learn design, product thinking, and AI in public. You learn alongside me.
Synsei is my research space. I try things, I write down what happened, and I share the notes. No guru talk. Just real experiments, in the open.
Latest notes
Short notes from what I am learning right now. Every note follows the same shape: what I tried, what happened, what I would do next time.

Write before you perform
Every story I tell starts on paper: setup, tension, turn, one line each. Writing first keeps me honest about what the story is actually about. Then I say it out loud. Never the other way around.

Accessibility is built in, not bolted on
If you add accessibility at the end, it shows. Contrast fixes, keyboard paths, clear language, these are design decisions, not a checklist you run the week before launch. Build them in from the first sketch and the product is better for everyone.
Learn
The good notes become lessons, organized into three tracks. Principles first, so a lesson works in any AI. Muse is the example, since that is what I use most.
Design
How I think about a screen before I draw it: hierarchy, contrast, and designing for people who experience the web differently than I do.
First lesson coming soon
Product thinking
Asking the right questions before building anything: what is the pain, what is the evidence, what am I assuming?
First lesson coming soon
AI
Working with AI as a thinking partner: how to prompt it, how to check its work, and how to keep your own judgment in charge.
First lesson: How I prompt any AI
Tools
The best lessons become templates and kits you can use in your own work. They grow out of the lessons above, so nothing here is built twice.
First kits are on the way.
