EPAPA: Turning a Teaching Method Into an AI Math MVP

EPAPA began with a teacher’s two-world approach to helping students overcome math anxiety, making abstract concepts feel more concrete through guided conversation. The goal was to turn that proven method into a digital experience students could use independently. In 4 weeks, I led the design from concept to MVP, shaping the conversational learning flow, visual language, prototype, and launch materials. The team had a testable product for onboarding early users and collecting feedback.

Challenge

The task was to translate a proven teaching approach into an engaging, AI-driven app and do it in just four weeks.
The main goals were to:
Design a learning flow that feels conversational and intuitive
Build a scalable UI system ready for future content modules
Deliver an MVP that could clearly demonstrate the learning logic to investors and testers

Role

Design Lead
Worked closely with the Founder, Product Lead, and Marketing Team to bring the concept to life from user flow mapping and interface design to product storytelling and presentation materials.

Work

I focused on turning complex learning theory into a simple, motivating product experience.
Key design features included:
Conversational learning: Students interact directly with an AI tutor via chat
Personalized feedback: Encouraging tone instead of corrections
Motivation loops: Progress tracking, streaks, and trophies to sustain engagement
Scalable design system: Built in Figma for rapid iteration and future lessons
Deliverables included UX flows, high-fidelity UI, an interactive prototype, and a full pitch deck and style guide for launch.

Impact

The MVP launch received strong external validation and early traction:
Funded through the Berlin Startup Grant (€50,000)
Accepted into AI Accelerator Berlin (€15,000 non-equity)
Praised by educators for transforming tutoring into a human-like AI experience
The result was an investor-ready prototype that positioned EPAPA as a promising EdTech startup redefining how students learn math with AI.
