COMPARISON
Interview Helpers vs ChatGPT for Interviews
ChatGPT is a great generalist. But a live technical interview is not the place for a browser tab. You need something that captures a screenshot with a hotkey, is invisible to Zoom, Google Meet, and Teams, and can transcribe what the interviewer just said while you type an answer.
That is what Interview Helpers is built for. For everything else — general writing, brainstorming, code review outside an interview — ChatGPT is still the right tool.
Interview Helpers wins 7 of 11 feature categories, ChatGPT wins 2. Updated August 28, 2026.

The three things ChatGPT can't do in a live interview
1. Stay hidden from screen share
Zoom, Google Meet, and Teams treat browser windows the same as any other window — if you Alt-Tab to ChatGPT, the interviewer sees the switch even if they don't catch the content. Interview Helpers runs as a transparent always-on-top overlay hidden at the OS level from every major screen-share tool, and is hidden from the Windows taskbar too. See stealth details.
2. Capture and send a screenshot in one keystroke
In ChatGPT you take a screenshot, alt-tab to the browser, paste, wait for upload, hit Enter. In Interview Helpers a single hotkey (Ctrl+1 by default) captures the current screen, attaches it to your prompt, and streams the answer instantly. Multiple screenshots within 2 seconds get batched into one turn so the AI can address each in order. See screenshot flow.
3. Listen to the interviewer
Behavioral rounds and system-design walkthroughs are spoken, not screenshotted. Interview Helpers' speaker mode streams system audio through Deepgram Nova-3 with ~200 ms interim transcription, then feeds the transcript to the AI when you toggle it off. ChatGPT has voice for input but not for capturing someone else's audio in real time. See speaker mode.
