AI interview copilot for coding and system design interviews
Listens to your coding and system design interviews, transcribes locally, and shows you an answer suggestion — using your own OpenAI or Anthropic key.
One-time purchase · 14-day refund · macOS & Windows
SyntaxCue is a desktop app for software engineers preparing for or taking technical interviews. It captures system audio during a call, transcribes it on-device, and generates a suggested answer with your own LLM API key — no subscription, no backend of ours in the loop.
How it works
- Listen. SyntaxCue captures system audio during your call.
- Transcribe locally. Speech-to-text runs on your machine, not a server.
- See an answer. A suggestion appears in a private hint window only you see.
Why this is different
- Local transcription — audio never leaves your machine
- BYOK — your own OpenAI/Anthropic key, no markup
- One-time purchase, not a subscription
- macOS and Windows
- Optional screen-share exclusion, off by default
- No account, no telemetry inside the app
Built for honest interview preparation and real-time support — not deception. See our position on using AI in interviews.
FAQ
Do I need my own OpenAI or Anthropic API key?
Yes — SyntaxCue is BYOK (bring your own key). You pay your LLM provider directly, at their cost, with no markup from us.
Does SyntaxCue record or store audio?
No. Audio is processed in memory, transcribed locally with whisper.cpp, and never written to disk or sent anywhere except your chosen LLM provider's API for generating an answer.
What's the refund policy?
14 days, no hoops — for technical issues or an accidental purchase.
Does the screen-share exclusion setting hide the app from the interviewer?
The setting keeps the hint window out of your own screen-share/recording stream — it's about your screen privacy, off by default, and always toggleable. Check your specific interview process's rules before using it.
