We tested every major AI coding interview assistant tool in 2026 - Medhly, Cluely, LockedIn AI, Final Round AI, and more. Here's which tools actually help during live LeetCode rounds, system design interviews, and take-home coding assessments.
Medhly responds in under 50ms, gives algorithm hints and code explanation in real time, and is 100% undetectable during screen share. Works on every major platform for $10/month.
Response speed, detectability risk, language support, system design coverage, and platform compatibility. Medhly tops all five categories.
