Lemon 8 Notes Tab Optimization

Lemon8 AI Image Creation Tool

In 2025 fall, I had the opportunity to intern as product design intern at Tiktok's global community product team, contributing to various teams during my period, working along creation, consumption, search, and events team.

Within 3 weeks of time, I worked with PM to design a 0 -> 1 AI image creation tool, resulting in 2,400+ global DNU, 14.2% retention, and a 7.82% increase in content posting.

As 2035 becomes the near future, future of mobility is already introduced with auto driving technologies, bringing conveniences like never before.

My Takeaways

Design changes often introduce trade-offs & shifts

Through hands-on experimentation, I learned to evaluate designs beyond UI comparison, using event-level data to understand impact, validate decisions, and guide future optimization. Along with skills of aligning potential changes to metrics of designing test groups with PMs in advances.

Structured communication & thinking

While presenting design ideas, I learned to focus on key points, articulate logic clearly, and aligning rationale with analysis. This improved both my decision-making and the clarity of my design explanations.

Be prepared in reviews to explain full context

Effective communication goes beyond presentation templates—it requires a clear understanding of the problem. Preparing context, logic, and updates ahead of reviews enabled more thoughtful responses, deeper discussion, and clearer decision-making.
