AI flashcards that turn note dumps and PDFs into addictive quiz sessions
Turn notes, PDFs, PowerPoint slides and YouTube videos into ready-to-quiz flashcards without writing cards by hand.
Automatic scheduling resurfaces cards right before you would forget them, so review time goes where it is needed.
Answer-first quizzing with instant feedback instead of passive re-reading, reinforcing long-term retention.
Streaks, points and social study sessions keep motivation high and make daily review a habit.

Run and scale durable AI agents on your own infrastructure
Every Actor gets a SQLite database and a filesystem, so an agent's memory and progress survive restarts and idle periods without a separate database.
Run untrusted or AI-generated code on your own infrastructure with fine-grained control over network access, filesystem permissions, and resource limits.
A node failure reschedules its Actors elsewhere with state intact, and multi-step work replays after a crash — with no checkpointing harness to build yourself.
Address an Actor directly over HTTP or hold a live WebSocket, and use the React SDK to subscribe components to an Actor's state in real time.
