Questor

A study app for Brazilian civil-service exams: AI-generated true-or-false flashcards from real exam questions, credits, a performance dashboard and mistake review.

What it does

Questor turns real exam questions into quick true-or-false flashcards generated by AI, so you can study in short bursts and see exactly where you stand.

• → AI-generated flashcards — built from real civil-service exam questions.
• → Credits — a credits system unlocks new cards as you study.
• → Explanations on demand — ask for an extra explanation whenever an answer isn't clear.
• → Performance dashboard — charts of how you're doing over time.
• → Mistake review — go back over the cards you got wrong.

How it's built

A native Android/iOS app in .NET MAUI Blazor Hybrid, with charts from Syncfusion. The demo beside this text is the real app (the same Razor pages as the Android/iOS builds) running in your browser with sample content and an in-browser demo backend: study a few cards, check the dashboard, spend some credits. Nothing leaves your browser.
