Problem
After a long day of work, planning errands feels like a second shift
Urban professionals know they need to stop at the pharmacy, grab groceries, and drop off a package. But deciding the order, checking if places are open, and managing unexpected wait times adds a cognitive load that compounds an already depleted state.
Existing tools solve parts of it— map apps navigate and task apps create to-do lists— but nothing bridges route optimization with personal energy levels or anticipates friction before you walk into it.
Goal
The solution needed to make fewer decisions visible
The goal of this Errand Planning project was for busy adults who live in walkable cities to solve for decision fatigue and to make the experience of running errands more enjoyable.
Our solution would leverage personalization, predictive, and generative AI to create an adaptive experience that learns from past user behavior.
Research
& Discovery
Efficiency is the goal, delight is the differentiator
We conducted four interviews with people aged 27–61 who run errands on foot in urban environments. Participants ranged from a structured loop-planner to a mood-driven spontaneous errand-runner. The differences in style were wide. The underlying frustrations were almost identical.




We built AI versions of our users, then interviewed them too
Interview data was synthesized into two custom interactive GPT models. We then conducted additional interviews with these personas to stress-test design decisions and surface edge cases real participants hadn't raised. The personas were a live reference throughout ideation, not a static document.

Key Insight
Participants and personas were frustrated with obstacles to their max efficiency, like wait times or carrying heavy burdens, but when asked what would make errands better, micro-joys like exploring new shops make going out feel worth it.
Concept & Design
Calm in the Chaos
We used AI to generate mood boards based around effortless living and reclaiming time. The palette we chose in the end represented the simplicity we wanted instill into the daily chaos of planning what to do after work.
Brighter, yet still muted palette keeps user calm and motivated
Colors are reminiscent of nature patterns to get users outside
Simple designs and ample spacing are less overwhelming, aligning with low cognitive load

Ensuring intuitive flows to reduce friction
The journey moves linearly through three lanes.
Overview: set energy, AI filters tasks by criticality, add tasks and get scored instantly.
Route planning: pick a vibe, configure joy stops if scenic, review the route with a live leave-by time — a Buffer Pivot alert can swap a stop before you leave.
Navigation: alternate between main stops and joy detours, rate each detour inline, finish the route and review. Ratings feed back into the AI, making the next session smarter.
