Architecture
OnPaper: Project-Based Technical Interview Readiness Platform.
At OnPaper, we believe memorizing DSA solutions is not enough. We turn any software repository into a structured, stateful curriculum inside your agentic IDE with explicit rubric grading, sandbox exercises, and FSRS spaced repetition.
Offline SQLite Durability.
Your source code never leaves your machine. OnPaper runs locally inside your agentic IDE adapter, maintaining exact persistent state in SQLite and syncing learning events to AWS asynchronously.
Misconceptions and failure traces are scheduled for revision using the state-of-the-art Free Spaced Repetition Scheduler, guaranteeing long-term mastery for staff and principal level interviews.
Your Edge in Staff Interviews
We don’t just test algorithmic syntax — we train you to defend every single architectural decision in your own production projects.
Vendor-neutral adapters for Cursor, Zed, Antigravity, and Claude Code
