How I approach
AI products.
SPARK is the lens I use to question product decisions — bringing usefulness, accessibility and human agency into the same conversation.
My lens for responsible AI
SPARK
Five principles.
One human perspective.
Thoughtful AI starts with the person using it. Each principle helps make a different trade-off visible.
Explore the full frameworkSupport, do not solve
Design AI to help people think and act, with suggestions they can understand, edit or decline.
Does this help the person make a decision, or take the decision away?
Explore the application lensProtect the person
Make choices, consequences and recovery paths clear. Avoid pressure and manipulative defaults.
Can the person understand the risk and choose with confidence?
