Interview Helpers
Interview Helpers is a Windows desktop overlay built for live technical interviews. Screenshot a coding problem, listen to your interviewer through the speaker, or ask a theory question, and get answers streamed back in seconds. It is designed around the interview workflow rather than a generic chat window.
The app runs as a stealth overlay that is invisible to OS-level screen capture, so Zoom, Teams, Meet, and Discord screen-shares never show it. An always-on-top transparent window sits over your IDE with click-through mode, hidden from the taskbar and toggled with a keystroke when you need to hide it.
System Design mode captures a screenshot and returns architecture analysis with rendered Mermaid diagrams inline. Speaker mode listens to your interviewer in real time, transcribes with zero latency, and fires back one-sentence answers when you toggle off. Screenshot AI reads code, LeetCode prompts, or design docs and walks through the answer.
Powered by GPT-5, GPT-5.4, Claude Sonnet 4.6, and Claude Opus 4.7 with conversation memory across follow-ups. Built for software engineers facing coding rounds, system design interviews, and fast verbal theory questions.
