Kasia Szczesna - Human-AI Interaction & Behavior

I help teams design human-AI experience & interactions that drive real decisions

The way you design AI interactions determines how your users think and decide.

Most AI product problems don't show up in usability tests. They appear in the invisible layer - where users misinterpret what AI is doing, trust it in the wrong way, or stop thinking for themselves. I help companies design that layer intentionally, using behavioral science.

About

I combine 14 years of product design experience with expertise in behavioral science, human-AI interaction, and AI ethics.

I have worked across Polish and international markets as a designer, trainer, and advisor - building UX teams, co-creating an international organization in the industrial sector, and developing my practice through hands-on work and programs at institutions including Harvard Business School.

My focus is the space between the interface and the user's mind - where design decisions shape how people interpret AI, how much they trust it, and whether they retain their own judgment over time.

I contributed to the development of the first European General-Purpose AI Code of Practice in collaboration with The AI Office at the European Commission.

I am the founder of BehaviorAI - a curated library of AI interaction patterns for product teams who want to design the behavioral layer responsibly.

How can I help you?

Let’s connect, talk through your challenges, and find the best solution for you and your business.

Design the behavioral layer of your AI product

For teams shipping AI features without a clear method for the invisible layer. I run workshops using the BehaviorAI Design Framework - diagnosing what blocks the right behavior, designing an evidence-based intervention, and reviewing the product through RIFT: Relationship, Interpretation, Friction, Trust.

Identify where your AI product is failing users

For teams with a working product and a behavioral problem they can't locate. I review the interaction patterns, map the mental models users are building, and identify where trust, interpretation, or friction are miscalibrated, before the problem shows up in churn or support tickets.

Prepare your organization for AI Act compliance

For companies integrating AI across products or internal processes. I help connect behavioral design, ethics, and regulatory requirements into a coherent approach. I work with legal advisors to help you understand what AI Act compliance means in practice not just in policy documents.

AI that guides without manipulating: ethical design of suggested prompts

Designing AI today means designing the architecture of choice. The goal is not to create a system that replaces human thinking. The real challenge, and the measure of good design, is to create AI that makes thinking easier and more structured while ultimately leaving the steering wheel in human hands.

Designing friction in human-AI interaction: when does making life harder for the user make sense?

Designing human-AI interaction shouldn’t start with the model, but with the user’s decision process. We need to understand when a user needs a quick answer and when they need a deliberate pause.

AI does not think. The problem is that we design as if it does.

Creating products based on LLMs today is not about hiding the limitations of AI behind great copywriting. Truly innovative design is about making the structure of these systems visible in order to protect the most important element of any system: human agency and responsible judgment.
