Live Demo
Your interviewer sees nothing. Not on screen share. Not ever.
Interviewer: So you've been at Amazon for 3 years. Impressive work on the order management system.
Candidate: Thank you! Yes, it's been a great journey so far.
Interviewer: "Tell me about a time you had to make a difficult technical decision under pressure."
💡 They might ask next: "What would you do differently?" or "How did you get team buy-in so quickly?"
GPT-4oSame answer UI. Different invisibility level. Both undetectable on tab/window share.
Features
Powered by Deepgram Nova-2 — the same engine used by NASA and Spotify. Handles accents, technical jargon, and fast speakers. Real-time with < 300ms latency.
Automatically classifies: behavioral, technical, system design, coding, follow-up, or situational. Adjusts answer format accordingly — STAR for behavioral, code blocks for coding, diagrams for design.
GPT-4o generates your answer before you even finish saying "That's a great question." Fast enough to feel like your own thoughts. Detailed enough to impress the interviewer.
GPT-4o is primary. If it's slow or down, Claude takes over automatically. You'll never get stuck mid-interview because of an API outage. Two brains, one seamless experience.
Every answer shows a confidence percentage. 90%+ = deliver as-is. 70-90% = review key points. Below 70% = answer needs your personal touch. Plus: follow-up question predictions so you're never caught off guard.
Smart Float (Free) — PiP floating window. Invisible when sharing a tab or window. Works in Chrome on all OS.

No matter what they throw at you — MuteCoach knows the format.
"Tell me about a time..." → Structured Situation, Task, Action, Result with quantified impact.
"Design a system that..." → Components, data flow, trade-offs, scalability considerations.
"Write a function that..." → Clean code with time/space complexity and edge case notes.
"How would you prioritize..." → Metrics, trade-offs, user segments, go-to-market.
"What would you do differently?" → Builds on your previous answer. Maintains conversation thread.
Maps to Amazon Leadership Principles, Google Googliness, Meta's core values. Company-specific framing.
We built MuteCoach with a paranoid level of privacy by design.
