✶ OVERVIEW
✶ OVERVIEW
Decision Trace is a lightweight Chrome extension that surfaces decision signals directly on top of AI responses. Instead of explaining what the model says, it reveals how much trust a response might deserve.

✶ WHY
✶ WHY
I spend a lot of time using AI tools in my everyday life. Over time, I realized that AI answers often sound confident, even when there is uncertainty or real-world risk hidden in the response. Without any clear structure, it is easy to accept these answers as reasonable and move on.
Decision Trace makes those hidden decision signals visible, without getting in the way of how people normally read and think.

with ChatGPT
Used to structure complex decision scenarios and define the system’s underlying logic.
Abstract intuition was translated into explicit reasoning models, forming the conceptual backbone of the project.

with Claude
Used to translate the defined logic into a working Chrome extension.
Enabled rapid prototyping of real interactions, shortening the design-to-code cycle.

While AI handled syntax and structure, creative decisions stayed human-led.
Based on quick user feedback, I adjusted tone, visual balance, and usability to better support real reading.

Signals are passive indicators, not instructions.
Users can open a Details view to explore a minimal decision tree without breaking reading flow.

The interface is signal-first and text-light. Inspired by system indicators and familiar UI patterns,
the UI stays calm, translucent, and non-intrusive.

Why Details helps?
Why Details helps?
Details doesn’t explain more. It shows what kind of reasoning is happening.

Where advice begins
Which real-world risks are involved
Whether claims imply evidence
Where uncertainty is introduced
