System design interview AI — a real-time copilot for senior rounds
System design rounds reward structured, trade-off-driven answers under pressure. Interview Copilot listens to the interviewer and gives you real-time architecture answers with trade-offs — scalability, consistency, bottlenecks — so you lead the discussion instead of scrambling.
Structured answers, instantly
As the interviewer frames the problem, the AI surfaces a clear structure: requirements, high-level design, data model, scaling, and trade-offs. You get talking points the moment you need them, not after the round.
Grounded in your experience (Pro)
With Pro, answers are personalized to your resume — so when you're asked how you'd design something, the AI ties it to your real stack and past projects, in first person, not a generic textbook answer.
Invisible and hands-free
It hears the interviewer through system audio and stays invisible on screen share across Zoom, Meet and Teams. No hotkeys mid-sentence — Auto-Answer responds the instant they finish asking.
