AI Interview Assistant for Technical and Engineering Interviews

SyntaxCue is a live, AI-powered interview assistant for technical and engineering interviews. During a real interview call, it listens to the conversation, transcribes it locally on your machine, and shows you a suggested answer in a private hint window — using your own OpenAI or Anthropic API key. Unlike tools built for studying beforehand, it’s a real-time interview assistant that works during the real interview call — suggesting answers live as questions come up. It covers coding problems, system design discussions, verbal technical questions, and behavioral questions within those same interviews — more on how each is handled below.

How it works

1. It listens to the call. SyntaxCue captures system audio from the interview — the same mixed output a screen recorder would pick up.
2. It transcribes locally. Speech is transcribed on your own machine with whisper.cpp. Audio is never written to disk and never leaves your machine.
3. It answers through your own key. The transcript — plus a screenshot, if you’re on a coding problem — goes straight to your own OpenAI or Anthropic API key. There’s no SyntaxCue backend in that path.
4. A suggestion streams back into a separate hint window, for you to read or paraphrase in your own words.

The same mechanism covers three kinds of technical-interview moment:

• Coding problems — sent to the model with an explicit, user-triggered screenshot (a button, an optional hotkey, or paste). There’s no continuous or automatic screen reading. Full mechanism on the coding interview helper page.
• System design questions — answered directly from the audio transcript, no screenshot needed. More on the approach in the system design interview cheat sheet.
• Verbal technical questions — the follow-ups an interviewer asks out loud (“what’s the complexity of that?”, “why that data structure?”) are answered directly from the transcript, the same way as system design.

What it’s not

Being precise here, because vague claims help no one:

• It’s not a mock-interview or practice tool. It doesn’t ask you questions, run rehearsals, or score your answers — it only assists during a real, live interview call.
• It won’t invent a personal story for a behavioral question. For something like “tell me about a time you handled conflict on a team,” it gives you a structural framework (STAR — situation, task, action, result) to organize your own real answer around, rather than writing a full answer the way it does for technical questions. Only you know your actual experience — SyntaxCue helps you shape it clearly under pressure, not invent it.
• It doesn’t read your screen automatically. Coding problems reach the model only when you take an explicit screenshot each time — no timer-based screen reading, OCR loop, or IDE integration.
