From the inside.

Cluely's 2025 transcript-exposure incident underlined what every privacy-aware candidate already suspected — interview transcripts are sensitive, and most copilots treat them as marketing telemetry. Here's what we built differently, and what to look for in any tool you trust with a live interview.

A walkthrough of the audio-capture, STT, LLM, and stealth pipeline that powers a real-time interview copilot. With code references and latency budgets.

We ran the same behavioral question through Mirly, Final Round AI, Cluely, Parakeet AI, LockedIn AI, and Sensei AI on the same MacBook Air M2 over the same network. End-to-end first-token times ranged from 127ms (Mirly) to 1,810ms (Final Round). The full methodology, raw numbers, and why everyone except us inflates their published claim.

Mirly's overlay is invisible to Zoom, Teams, Meet, and Webex because it uses NSWindow.sharingType on macOS and SetWindowDisplayAffinity on Windows — the same APIs 1Password and Netflix use. No kernel exploit, no hidden process, no thing-that-will-break-next-Tuesday.

Half of Final Round AI's 1-star Trustpilot reviews are billing complaints. We built Mirly's pricing as the explicit inverse — opt-in renewal, 5-day reminder email, never a silent charge. Here's why we made it the headline.
