Key Moments in UX Design (newest sketch)
10 + 1 design resources I loved the most in December
🛠️ Design better AI products — even if you’ve never worked on one before. A workshop by Florian Boelter
AI is making its way into more product experiences, but most designers haven’t been taught how to design for it. How do you build trust when outputs are probabilistic? What does “good UX” even mean when the system might be wrong? This workshop breaks it down.
Led by Florian Boelter, Staff Product Designer at Juro, we’ll go hands-on with real UX patterns and decision-making tools you can use when designing AI-powered features — from uncertainty and fallback states to human-in-the-loop workflows. We’ll work through a practical, hands-on exercise where we critique and redesign an AI product experience together. Whether you’re preparing for your first AI project or want to build a strong case study for your portfolio, this is where to start.
I attended one of Florian’s workshops before, and I had a blast! Here is my summary of it.

💻 New article: How AI “remembers”, and what it means for you as a builder
In the article, I cover how context works, what influences GenAI apps’ performance, what tokens are, and how context grows with each prompt and response. As always, I used hand-drawn illustrations to make concepts more comprehensible, e.g. this one is about “turns” in an interaction with AI (read the article for more details):
✏️ Key Moments is UX Design
The difference between products that retain users and products that lose them often comes down to some key moments in the user journey. You shouldn’t leave these moments to chance, instead, map them out and design for them in a deliberate way.
My newest sketch highlights these moments: Aha Moment, Activation Moment, Moment of Truth, Magic Moment & more.
I’m going to publish a more detailed article, you’ll find it here soon.
✏️ Favorite resources
Here are my favorite discoveries of December, 2025:
#1 Interviews about visual design by Anthony Hobday
While it is not a new resource, I didn’t know that one of my favorite designers, Anthony Hobday, interviewed so many designers, and they “only talked about visual design.”
E.g., here is a great piece of advice from the interview with Erik Kennedy:
”I’d recommend analyzing your gut reaction to any particular aspect of any design.
For instance, if you notice a font feels very friendly, try to analyze why. What about it makes it feel friendly? Is it a quality you can identify in other fonts that feel friendly? Is it a quality noticeably absent in decidedly not-friendly fonts? […]
Or maybe you’ll find that most professional designs use much more whitespace than your own attempts. Or maybe you’ll notice that most divider lines in great designs are really very light, etc.”
Btw. if you want to learn more about such techniques, my How to train your designer eye & develop your design skills course teaches you exactly that (it is about how you can use design inspiration effectively, how to analyze UI designs and how to practice & experiment)
#2 Inspo.page by Kevin Kopp
The website inspo library, curated at the component level.
I added it to my article about design inspiration (it contains a huge list of my favorite inspiration sites).
#3 10 Usability AI Principles by Matt Soriano
#4 Prompt builder and Gen AI Guide by Proper Prompts by sf.co

#5 The Art of Vibe Design by Ivan Cernja
”So stop waiting for permission. Stop waiting to “learn enough.” Start describing what you want. The bridge is built. Walk across it.”
#6 Designing For Stress And Emergency by Vitaly Friedman
Practical guidelines on designing time-critical products that prevent errors and improve accuracy.
#7 Design is more than code by Karri Saarinen
”The bigger question to me is what happens to how we see designers contributing in the future, especially now with AI and these new tools.”
#8 The Architecture of Anxiety and Shame Part 1 and Part 2 by Todd Libby
”I wanted to go over four patterns, four of many patterns, that are used to play with people psychologically, that draw out the anxiety and fear, the guilt and shame, and how these patterns are used and what we can do to combat them.”
