Gamifying Writing: In-App Economy for Spark Space

I designed a light‑touch in‑app economy—SageCoin—paired with Daily Missions, Streak Rewards, and an AI‑Tutor Marketplace.

Five unlockable tutors, each 50 SageCoins.

Modal shows personality tags + cost banner.

“Create your own tutor” teaser primed future feature adoption.

Behavioural hook: competence + autonomy + relatedness.

Spark Space is a free, AI‑powered learning tool that gives teachers instant, standards‑aligned feedback and students a personal writing coach. To scale sustained engagement, I designed SageCoin—a lightweight in‑app currency tied to writing milestones. The goal was to motivate students intrinsically, without adding grading overhead or gimmicky distractions, and to give teachers a frictionless way to keep their classes writing week after week.
