StealthCoder vs Sensei AI
The Sensei AI alternative for coding interviews
Updated June 2026
Sensei AI claims it operates undetected whether or not you share your screen, but hands-on reviewers found the opposite: its browser extension is visibly active during screen sharing, which one review called unusable in real interviews. Another concluded it is better for mock interviews than live ones. Sensei is built around behavioral answers with a coding copilot attached. StealthCoder is a native desktop app with no browser extension to expose, invisible during the share, focused on coding and system design.
Built by an engineer who passed his own loop with this and refused to ship anything he wouldn't run himself.
