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 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 build) 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.
