Real-time answers, LeetCode hints, and system design architecture streamed directly beneath your webcam — 100% invisible to screen share.
“How would you design a distributed rate limiter handling 100k req/sec across multi-region clusters?”
Prevents traffic spikes at window boundaries compared to fixed windows.
Executes ZREMRANGEBYSCORE and ZADD atomically in a single roundtrip.
Falls back to local token bucket if Redis p99 exceeds 15ms.
Engineered from the kernel up to eliminate every detection vector.
Taps physical system audio directly via CoreAudio/WASAPI. Never joins your meeting, invites no guest bots, and adds zero participant tiles.
Window server flags instruct the OS compositor to omit HUD pixels from Zoom, Teams, and Google Meet screen share feeds.
Streaming speech-to-text paired with speculative model decoding yields live talking points before the interviewer stops talking.
Connect your OpenAI, Claude 3.7, Groq, or local Ollama instances. Zero audio telemetry is sent or stored on our servers.
Get clean architectural summaries, trade-offs, and syntax-highlighted code snippets right after your interview ends.
Smooths 100k req/sec boundary bursts over strict Token Bucket.
Eliminates distributed race conditions in a single network roundtrip.
Falls back to local RAM buffers if Redis cluster latency exceeds 15ms.

No. Live Interview Helper operates strictly at the OS window-server level using native hardware compositor flags. Screen capture APIs inside Zoom, Microsoft Teams, Google Meet, and CoderPad query the window server and receive an empty feed for our process. Furthermore, it never joins your call as an external bot tile or participant.
