Hear the question.
Know the answer.
Luecentra listens to your interview live, detects the kind of question instantly, and feeds you a human-sounding line to say — plus full coded solutions and system-design walkthroughs when it counts.
Coding and system design — handled.
The two hardest rounds in any software loop. Luecentra doesn't just hand you the answer — it shows you how a strong engineer thinks through it out loud, so what you say sounds like real reasoning, not a recital.
A real solution, reasoned out the way you'd actually say it.
From two-pointers to dynamic programming, Luecentra builds the answer from the problem in front of you and narrates the thinking — so you can keep up and speak with confidence.
- Reads the LeetCode/HackerRank problem straight off your shared screen
- Restates it, asks the clarifying questions, then talks through the naive approach before the optimal one
- Writes a complete, idiomatic solution built from THIS problem — never a memorized template
- Calls out time & space complexity and dry-runs a real example out loud
Scope, architecture, trade-offs — in a calm human voice.
Luecentra walks the senior-level framework and thinks out loud the way a strong candidate does — “before I design anything, let me scope it…” — so you lead the discussion instead of reciting a diagram.
- Runs the real Google process: scope first, separate functional vs non-functional requirements
- Picks the constraint that actually drives the architecture, then deep-dives the bottleneck
- Explains why the simple approach breaks and weighs the trade-offs — consistency, latency, scale
- Back-of-envelope numbers, justified — so you sound senior, not scripted
It sounds like you — not like ChatGPT.
Every answer is written to be said out loud: contractions, natural connectors, a little thinking-out-loud before the point lands. The reasoning is visible, the tone is human, and the depth is all there — so interviewers hear a sharp engineer working through the problem, never a candidate reading off a screen.
They share the screen. They never see Luecentra.
Luecentra floats on your screen but is invisible to screen-share and recording. Drag the handle — watch it vanish the instant you cross into what the interviewer actually sees.
Drag the handle ↔ to compare your screen with the shared screen.
A real copilot — not a chatbot in a tab.
Luecentra hears the question, reads your screen, knows your résumé, and answers in your voice — all while staying completely invisible to the interview.
100% private & undetectable
StealthInvisible to screen-share, recording, and proctoring overlays on Zoom, Meet, Teams, Webex, HackerRank and CoderPad. They share their screen; Luecentra stays on yours alone.
Blazing-fast transcription
Real-timeDeepgram Nova-3 captures the interviewer in real time, so the answer is forming before they finish the sentence.
GPT-5.5 high-reasoning answers
AccuracyCoding and system-design questions get the full reasoning budget — correct, idiomatic, and explained the way a strong human would.
Full coding-interview support
LeetCodeReads the LeetCode-style problem off your screen and writes a complete, syntax-highlighted solution with complexity called out.
Auto question detection
Knows the moment a real question is asked — and what kind it is — then matches the depth without you lifting a finger.
Résumé & knowledge base
Upload your résumé and notes. Behavioral answers are grounded in your real experience, not a generic template.
Works on every platform
Zoom, Google Meet, Microsoft Teams, Webex, HackerRank, CoderPad — and any browser tab. No integration, no bot in the call.
Human-sounding delivery
The “Say This” line reads like you on your best day — contractions, natural connectors, reasoning out loud — never a robotic script.
AI notes after the call
Every session is saved with a clean transcript and answer history you can review and learn from afterward.
It detects the question type — and matches the depth.
Ask for a definition and you get a crisp sentence or two, fast. Ask a real system-design question and Luecentra runs the full Google process: scope first, design for scale, talk trade-offs.
Full coded solutions, built for the problem in front of you.
For LeetCode-style questions Luecentra spends its full reasoning budget: it explains the approach in plain English, then writes a clean, syntax-highlighted solution with the complexity called out — ready to walk through out loud.
- • Approach first, then the code — never a wall of text
- • Real solution derived from the actual prompt, not a template
- • Time & space complexity stated every time
Tuned to your role, level, and résumé.
Tell Luecentra who you are and what you're interviewing for. Every answer is framed for your target role and grounded in your own experience — so it sounds like you, on your best day.
Grounded in everything it can see.
Live transcript, screenshots of the shared screen, your résumé, and your personalization all feed the same answer — so Luecentra responds to the real moment, not a generic prompt.
Candidates don’t just pass — they sound like themselves.
Real feedback from people who walked into the hardest rounds of their search with Luecentra in their ear.
I froze on a sliding-window question and the “Say This” line had me talking in about two seconds. The detailed answer kept me steady when the follow-ups came.
Honestly expected another generic AI helper. But a clean, human answer in my ear during the system-design round was the difference between rambling and sounding senior.
It answers what was actually asked, not some template. Felt like having a really strong friend quietly on the call with me.
Setup took five minutes and then it just worked. The screenshot context is underrated — it read the prompt off my screen and answered the real question.
“Say This” first, details after — that pacing matches exactly how interviewers want you to talk. Used it across two weeks of onsites.
Skeptical at first, but the code it writes is clean and the complexity call-out at the end made me look like I’d thought it through. Landed the L5 offer.
