Desktop Pet
A rapid validation experiment spanning user need, a macOS prototype and two social posts with about 570,000 views.

Context
Starting from desktop companionship and lightweight productivity, explored a desktop product combining a character companion, to-do reminders, hydration reminders and customization.
Product Build
Independently defined the core interactions and product rules, then used Codex and Electron to build a macOS prototype with a transparent always-on-top window, character dragging and locking, click-through behavior and continuous head tracking.
Validation
Iterated on animation anchors, motion interpolation, tracking smoothness and desktop interruption, then validated demand through two social posts with approximately 570,000+ views and 25,000+ likes.

Make utility feel lighter and companionship feel natural on the desktop.problem
Desktop reminder tools can feel rigid, while companion-only characters may lack lasting utility. The product must balance function, emotion and desktop interruption.
Companionship should not interrupt work, and utility should not break the character experience.insight
Desktop companionship works best when it is low-interruption, persistently visible and lightly interactive. Reminders and customization can create reasons to return.
The character is the entry point; lightweight productivity creates lasting value.solution
Designed a desktop-pet prototype that brings character interaction, to-do reminders, hydration reminders and customization into one lightweight experience.
Use companionship to carry reminders and give productivity features emotional value.product design
Independently defined core interactions and product rules, including character drag and lock, click-through behavior and continuous head tracking toward the cursor.
Interactions need to feel alive without getting in the way of desktop work.ai workflow
Used Codex and Electron to build a macOS prototype, translating product rules into testable desktop interactions and refining motion logic throughout development.
AI-assisted development shortened the path from interaction concept to testable prototype.build
The prototype implements a transparent always-on-top window, character dragging and locking, mouse click-through, and continuous head tracking.
The concept has been advanced into an interactive macOS prototype.validation
Iterated on animation anchors, motion interpolation, tracking smoothness and desktop interruption, then tested audience interest through two social-media product demos.
Technical smoothness and perceived interruption directly affect whether users want to keep the character on their desktop.results
Two product-demo posts received approximately 570,000+ views and 25,000+ likes, providing an early demand signal for desktop companionship and lightweight reminders.
Social data validates concept appeal, but not long-term retention.
reflection
Social response demonstrates the concept’s appeal. The next step is to validate real usage of reminders, long-term retention and whether customization creates sustained motivation.
Moving from “interesting to watch” to “worth using long term” requires in-product validation.
