An invisible real-time copilot during live interviews, AI-powered practice sessions, and deep post-interview reports — everything to help you prepare smarter and perform at your best.
Your interviewers see only your face and shared screen. Corebrum AI renders on your local display at the OS layer — never integrated with meeting software, never visible during screen share.
Watch the invisible overlay detect questions, surface context, and deliver answers in real time — all while you screen share.
Every detected question unlocks multiple answer frameworks — STAR for behavioral, architecture flows for system design, and syntax-highlighted code solutions for coding interviews. Switch modes live in under 300ms.
Pixel-faithful replica of the real Corebrum AI desktop overlay — same glassmorphism, color coding, and syntax-highlighted code panel.
Every feature is built around a single mission: get you from first application to signed offer, faster than you ever thought possible.
"I went from bombing three rounds in a row to landing a Senior PM role at a Series B startup — in six weeks. The Real-time Copilot and Practice Studio together are genuinely unfair. I felt like I had a coach in my ear the entire time."
No other tool combines a real-time live overlay, resume-grounded answers, and full post-session reports — in one platform.

From first-time job seekers to experienced engineers — Corebrum AI helps candidates at every stage walk into interviews prepared and walk out with offers.
"I did 12 Practice Studio sessions in one week and watched my readiness score climb from 54 to 91. By the time the real interview came, I wasn't nervous — I was ready. Landed L5 at Google on the first attempt."
"The Session Report after my first mock was a wake-up call — it pinpointed three question categories where I was losing points and exactly why. I fixed every gap. Two weeks later, offer in hand."
"I have ADHD so interviews have always been brutal. The Real-time Copilot was like having a calm, brilliant colleague in my ear. I didn't blank out once. The interviewer said it was the best conversation they'd had all month."
"Seven years out of the workforce. I had no idea how to frame my experience for modern hiring. The AI Copilot rebuilt my career narrative from the ground up. I cried on the call when they gave me the offer."
"Uploaded my resume and the JD to the Knowledge Hub. The difference in answer quality was instant — every response the copilot surfaced was grounded in something I'd actually built. Zero generic advice. Just my story, told well."
"Hit a system design question I'd never seen before. The copilot surfaced a scalability framework in under a second. I walked through it step by step, got stellar panel feedback, and had a Meta offer email at 8am the next day."
Prepare smarter. Perform better. Let Corebrum AI be the invisible edge you bring into every room.
