I guess I just wanted to build my own, because my use case was really narrow and I knew it wouldn't take a lot of time. Guaranteed to not have any ads and trackers. Also needed an excuse to fully take github copilot's agentic coding for a spin.
Very nice. On my end, I vibe coded a daily newsletter that sends me a short text in Latin each day that describes an event that happened on that day in history.
Is there any functionality/usability reason you use this instead of an existing flashcard app like Anki?
