SyntaxCue listens to your technical interview, transcribes it locally, and shows you an AI-generated answer suggestion โ€” using your own LLM API key. One-time purchase, macOS and Windows.

SyntaxCue is a downloadable desktop app for developers for technical job interviews โ€” coding and system design.

During a video call, SyntaxCue captures system audio and transcribes it locally on your machine. It then shows an AI-generated answer suggestion in a private hint panel, using your own OpenAI or Anthropic API key (bring-your-own-key) โ€” there's no backend of ours in the audio or API path, so your interview content and your key never pass through our servers.

Pricing is a single $79 one-time purchase โ€” no subscription, no recurring charges, and unlimited use forever once purchased. Before buying, a free tier lets you try it with a limited number of hints, metered by usage rather than a calendar countdown.

SyntaxCue runs on macOS and Windows as native desktop apps (no Linux or mobile client). An optional setting can keep the hint window out of your own screen share; it's off by default and can be turned off at any time.
