Upload a document, paste a video or podcast link, clip a web article — AI turns it into summaries, flashcards, quizzes, glossaries and mind maps, and an FSRS-4.5 scheduler drives it into memory.
I study with this platform myself and publish what it generates using the share button, real output from my own material, open to anyone, no account needed.

AI providers — Gemini · OpenAI · Claude · Grok · DeepSeek · Kimi · Doubao · Qwen · Wenxin Yiyan. Switchable from settings; keys stay client-side and travel per request.
Backend — .NET 10 · ASP.NET Core · EF Core 9 · MediatR · FluentValidation · SignalR · PostgreSQL + pgvector · S3 · yt-dlp · ffmpeg · Whisper.net · JWT
Frontend — React 19 · TypeScript 5.8 · Vite 6 · TailwindCSS 4 · React Router 7 · Tiptap · Markmap · Service Worker + idb-keyval
Mobile — React Native 0.86 · Expo SDK 57 · expo-router (rn/README.md)
Shared — packages/core (@study/core): API services, SSE reader and DTOs used by web/ and rn/
Architecture — Clean Architecture · CQRS · Repository + Unit of Work · SSE streaming
Needs .NET SDK 10 · Node 18+ · PostgreSQL 17 with pgvector (stock Postgres will not migrate) · ffmpeg · AWS CLI, plus a Gemini key, Google + GitHub OAuth apps, SMTP/SES email, and S3 or MinIO. Redis is optional and off by default.

in at build time — rebuild the frontend images after changing them.
AWS — ./deploy.sh provisions ECS Fargate behind an ALB, S3 + CloudFront for the web and
admin builds, and points the API at Supabase. No RDS, no ElastiCache.
