What it does

• Automatic multi-step information extraction from PDF(s): information gets extracted from uploaded pdfs into structured format, automatically added to the available study topics
• Tutoring loop: a per-topic AI tutor asks exam-style questions, grades your answers with structured corrections
• Language switching and provider selection: UI in German, English, Japanese or Korean; Gemini or OpenRouter as backend with selectable tutor model

Implementation notes

• React 18 + TypeScript + Vite + Tailwind
• small Hono (Node) API for file-based persistence and the server-side PDF to content pipeline
• Streaming uses a hand-rolled parser for Gemini's chunked JSON output (no SDK)
• model output rendered as sanitized markdown
• API keys live only in the browser's localStorage.
