StudyBuddy

Built first in 24 hours for a hackathon, then rebuilt into a scalable AI study app that turns text, images, and PDFs into flashcards, quizzes, study plans, analytics, and an AI tutor.

Reached 2.5k installs and $40 revenue through ASO and organic discovery with 0 marketing spend.

Migrated from Supabase to a Bun + Hono backend on Cloudflare, with OpenRouter handling automatic LLM routing.
