Interview Coder

Undetectable AI assistant for live technical interviews

Real-time coding assistance

The assistant transcribes the question as it is asked and returns a working solution you can read from the overlay, aimed at LeetCode-style prompts.

Live audio transcription

Captures and transcribes the interviewer's speech so the AI can follow questions delivered verbally during the call.

Stealth overlay

The window stays out of screen shares, dock, taskbar and the activity monitor, with click-through behaviour and a disguised process name.

Coverage across interview formats

Targets coding, system design, behavioural, full-stack, data, AI/ML, consulting, trading and product interviews rather than only algorithms.

Strengths & Pros

+Purpose-built stealth features that go beyond a normal AI chat window
+Supports audio input so it can follow spoken questions during a live call
+Works across coding, system design and non-technical interview formats
+Publishes a compatibility list that is reported as retested against major interview platforms
