AI Overlay for Triplebyte (Karat NextGen) Assessments on Mac
Triplebyte adaptive coding quizzes were acquired by Karat in 2023. The assessment technology and content library now power Karat adaptive screens, including the Karat NextGen launch in late 2025; the Triplebyte sourcing marketplace itself wound down years ago.
The Triplebyte product candidates remember was an adaptive multiple-choice and short-coding quiz that adjusted question difficulty in real time based on prior answers. Karat absorbed the content library and the adaptive engine; today the same technology surfaces inside Karat NextGen as the async front end before a live Interview Engineer screen. From a capture standpoint these adaptive pads are simpler than CoderPad or HackerRank because they do not need a multi-file IDE.
Key points
- The adaptive assessment is a sequence of single-question pads, not a long-form IDE recording.
- Question difficulty adjusts based on your prior answers; the engine grades the submitted answer, not your process.
- There is no desktop installer; the pad is a browser tab with no privileged access to macOS windows.
- Tab-focus tracking inside the pad fires on browser blur events, which toggling the overlay does not trigger.
- Recruiters receive a per-skill score band; no video, no screen recording, no process listing is sent.
- If the same employer later runs a live Karat IVE screen, that uses WebRTC screen share.

Common questions
Is Triplebyte still its own platform?
No. Karat acquired the assessment technology in 2023 and shut down the Triplebyte sourcing marketplace.
Will the adaptive engine notice unusual answer patterns?
The engine adapts difficulty based on correctness and timing.
Does the adaptive pad require Screen Recording permission on Mac?
No. It runs in the browser without invoking getDisplayMedia or ScreenCaptureKit.
Will my employer see the overlay in the score report?
No. Score reports are numeric per-skill ratings with optional question-level breakdowns.
