Which should you pick?
Pick Interview Helpers if
- You want to switch between GPT-5.6 and Claude 5 for different question types (fast reflex vs deeper reasoning) without changing tools.
- You're prepping for or taking system-design rounds — the dedicated System Design mode renders proper Mermaid flow, sequence, and ER diagrams inline.
- You need live speaker transcription during behavioral / spoken rounds — Deepgram Nova-3 streaming gives you interim results in real time.
- You take rapid multi-screenshot captures and want them synthesized into a single answer that addresses each in order.
- You already have an OpenAI or Anthropic API key and want unlimited premium-tier usage on your own bill.
Pick Interview Solver if
- You've already built a workflow around it and don't need model switching, speaker mode, or system-design diagrams.
- You're on macOS today — we ship Windows first; macOS is in beta.
