Features
Every feature earns its place.
No bloat. No demos that don't work in real life. Every feature in Klayr solves a real problem — the kind you encounter mid-interview.
Speed
Zero dead-time from question to answer.
Three systems work in parallel so you never sit in silence waiting for a response — no matter how fast the questions come.
Every screen, captured instantly
Klayr watches all your connected displays at once. Questions that appear on any screen — your video call, a shared coding environment, a slideshow — are detected the moment they show up. No switching, no manual input, no missing anything.
Supports up to 6 monitors simultaneously.
Race Mode — the fastest answer wins
Race Mode fires two AI providers at the same moment a question is detected. Klayr streams whichever responds first, then quietly cancels the other. The result is consistently faster answers and no single provider slow-down ruining your timing.
~40% faster at the 95th percentile vs single-provider.
Follow-up questions never get lost
If a follow-up appears while you're mid-answer, Klayr queues it silently. The moment your current answer finishes, the next one begins — in order, with no gap. You're always one step ahead.
Unlimited queue capacity. First-in, first-out order.
Audio
Hear it. See it. Answer it.
Full audio capture means Klayr works even when questions are spoken — not just typed on a screen.
Best-in-class speech transcription
Spoken questions are transcribed in real time using industry-leading speech recognition — accurate across accents, technical vocabulary, and noisy environments. System audio and your microphone are captured separately and combined intelligently.
Supports 50+ languages.
Real-time partial transcripts
You don't have to wait for a full sentence to be spoken before Klayr starts working. Partial transcripts stream in as words are detected, so the answer starts forming before the question is even finished.
Falls back gracefully when unavailable.
Smart noise filtering
Klayr distinguishes human speech from background noise, music, typing, and alerts. Only actual spoken questions trigger a response — so you're not flooded with false positives or burning through usage on background noise.
Three adjustable sensitivity levels.
Hold Mode for in-person interviews
Interviewing in person? Hold Mode queues detected questions silently until you're ready to review them — at a natural moment, on a second device, or between rounds. No live streaming, no visible screen activity.
Toggle on and off with a keyboard shortcut.
Stealth
Your private command center.
Multiple independent panels. Completely hidden from anyone watching your screen.
Up to 5 independent panels
Open multiple Klayr panels and position them across any monitor. One for live answers. One for your behavioral story bank. One for system design templates. Each panel is independent, resizable, and persists between sessions.
Up to 5 panels. Drag-and-drop positioning.
Completely invisible to screen share
Every Klayr panel uses an operating system feature that excludes it from screen capture. Zoom, Google Meet, Teams, Webex — none of them can see Klayr's window. Your interviewer sees a blank area. You see everything.
Works on macOS, Windows, and Linux.
Code Runner
Write it. Run it. Ship it.
The only interview tool with a built-in code execution environment — no tab switching, no context loss.
Run code without leaving Klayr
Klayr includes a sandboxed code runner that supports Python, JavaScript, TypeScript, Java, C++, Go, and Rust. Write, run, and verify code inline — with output, errors, and exit codes shown immediately.
7 languages. Sub-second execution for typical problems.
One click from answer to running code
Every AI answer that contains code includes a button that pulls the code directly into the runner with the correct language already detected. You go from suggestion to verified, working code without touching your clipboard or switching windows.
Automatic language detection.
AI
The intelligence behind the answers.
Multiple AI providers, six interview modes, real-time refinement, and a post-session debrief that makes every interview a learning moment.
Three AI providers. Always the best one.
Klayr works with three leading AI providers — each with different strengths. Configure which one you want for regular answers, which for Race Mode backup, and which as a fallback. Switch providers mid-session without restarting.
Switch providers without restarting.
Your keys. Your costs. No middleman.
Paste your API key once — it stays on your device and is never sent anywhere else. Every AI request goes directly from your machine to the provider. You pay their standard rates. We take nothing.
Keys are stored locally and never leave your device.
Not happy with the answer? Fix it instantly.
Three refinement actions are available for every answer: Rephrase for a different angle, Expand for more depth and examples, Shorter for a tighter delivery. Each refinement is independent — rephrase, then expand the rephrased version.
Full history of original answer and all refinements.
Learn from every interview.
After each session, Klayr reviews every question and answer, scores your performance, and gives you specific notes on where to improve. The debrief is stored locally and exportable — a record of exactly how you're getting better.
Scores: quality, timing, coverage. Exportable as PDF.
Stealth & Control
Invisible. Instant. Always ready.
Klayr is engineered to disappear into your workflow — fast keyboard shortcuts, adjustable visibility, and a footprint small enough to forget it's there.
Control everything without clicking
Every action in Klayr has a configurable global keyboard shortcut — toggle visibility, skip to the next answer, trigger refinements, open the code runner, pause detection. Shortcuts fire even when Klayr's window isn't in focus.
All shortcuts configurable. Vim-style navigation available.
Dial in exactly how visible you want to be
Slide Klayr's window from fully opaque to nearly transparent. At low opacity it blends with your background — readable to you, invisible in peripheral view. Adjust it for your monitor, your lighting, and your comfort level.
Opacity range: 20%–100%. Keyboard shortcut toggle.
