Logan

Inspiration

We all been DOOMSCROLLING way too much on our iPhones (tm). This was a problem. DOOMSCROLLING wastes hours of our day, which add up to days, weeks, months, and even years over a lifetime. Yikes! We wanted to solve this problem, but we also realized that DOOMSCROLLING is pretty fun. Therefore, we decided to make DOOMSCROLLING productive! :D

What it does

Logan is an iOS app that allows you to infinitely scroll interactive modules across a variety of educational topics. Literally just open the app and start doomLEARNING! :D: D

How we built it

Frontend: Swift and SwiftUI. BTHO React native truthers. Server: Elysia + Bun. We love type safety! Database: MongoDB. We designed an extremely flexible data model that was best suited for a document store AI: Gemini for built-in structured outputs Other: We generate content via asynchronous python workers

Challenges we ran into

Wrangling Gemini, even with structured outputs. Still so much work to be done here. It's very exciting.
Modeling the exact same data across multiple different formats without messing it up (Swift structs, Python classes, JSON)

Accomplishments that we're proud of

Automated, structured, effectively infinite content generation via LLM
Fun and interactive modules in the app UI

What we learned

LLMs are extremely powerful tools for content generation that can beat older, cumbersome methods at a fraction of the time and cost. We believe they are the future for education and interactivity, and that interfaces should continue to evolve with model quality
