AI & Product Design

AI is a quality lever and I’ll show you how I integrate it into my workflows.

For me, it is mainly a way to think better: explore more options, challenge assumptions, structure decisions, and test ideas earlier.

It can help things move faster, but the Product Designer still keeps the responsibility for framing the problem, making trade-offs, understanding users, and shaping the final craft.

A qualitative view of where I trust AI, and where I deliberately keep more human control.

This scoring is not a scientific measurement. It is a personal reflection grid to separate areas where AI genuinely improves my reasoning from areas where I deliberately keep a lower level of trust.

My AI-augmented workflow

At every step, I keep the decision and design judgment. AI helps me structure, challenge, explore and document, but it does not decide for me and does not create evidence.

Discovery

Structures notes, qualitative signals and quantitative data
Helps identify patterns and contradictions
Challenges early assumptions
Does not replace user interviews
Does not decide what is a real insight
Does not turn correlation into evidence

Problem framing

Helps formulate multiple problem angles
Makes assumptions and fuzzy areas visible
Suggests clearer reformulations
Does not choose the problem to solve
Does not replace business context
Does not validate product priority alone

Exploration

Broadens the solution space
Generates variants, scenarios and edge cases
Helps compare the strengths and limits of each direction
Does not choose the final solution
Does not replace product taste
Does not guarantee technical feasibility

Prototyping

Creates interactive flows
Documents Figma references in design.md
Documents trade-offs and decisions in Roadmap.md & Memory.md
Does not produce production code
Does not create anything in Figma or in the design system
Does not validate the experience without user testing

Testing

Helps prepare test scenarios
Spots possible bias in questions
Structures observed feedback and signals
Does not replace real users
Does not turn a weak test into strong evidence
Does not decide alone whether a solution works

Arbitrage

Synthesizes options and their compromises
Makes risks, costs and benefits visible
Helps formalize decision criteria
Does not make the final decision
Does not replace product responsibility
Does not decide without human, business and technical context

Handoff

Creates a structured package for the engineering team
Helps produce Design.md, Memory.md, Roadmap.md and Specifications.md
Turns the validated prototype into a more usable support for developers
Does not replace discussion with engineers
Does not guarantee technical quality alone
Must not introduce unvalidated rules

My prototyping loop with coding agents

I don’t ask AI to design on its own. I feed a controlled loop with tasks, design context and validations.

Design.md

01

UI choices, flows, states, edge cases and interaction logic.

Memory.md

02

Reasoning, trade-offs and mistakes already encountered. Helps the developer understand why a decision exists.

Roadmap.md

03

Priorities, task status and next steps.

Specifications.md

04

Functional rules, constraints and acceptance criteria.

Validated repo

05

Validated prototype used as a behavioral reference.
