Answer system design questions with a clear structure
GhostInterview helps you move from vague prompts to a coherent architecture in minutes. It provides a clean outline, trade-offs, and next steps so you can explain your reasoning confidently.
What you get in a system design interview
- Real-time architecture outlines with APIs, data models, and service boundaries
- Trade-off guidance for latency, cost, consistency, and availability
- Scaling plans including caching, sharding, and queues
- Interview-ready explanations with clear decision points
- Voice mode with optional auto-trigger for hands-free interviews
- Voice Knowledge Base to include resumes or project context
- Works with both voice prompts and screenshot-based inputs

FAQ
Does GhostInterview help with non-LeetCode system design questions?
Yes. It is built for real interviews and covers open-ended system design prompts, not just LeetCode-style coding problems.
Will GhostInterview appear on screen share?
GhostInterview is designed to stay invisible during screen share by rendering its overlay outside captured layers on supported platforms.
Can I use it during live voice interviews?
Yes. Voice Mode transcribes questions in real time and delivers a structured system design answer while you speak.
Does it help with trade-offs and scaling decisions?
Yes. It highlights latency, cost, availability, and consistency trade-offs so you can explain design choices clearly.
