Hey PH — I'm Lennon, the maker. I built this after watching a friend bomb three FAANG onsites in a row. He knew the material; he froze under the pressure. Existing tools (Cluely, etc.) were either obvious to interviewers or required pasting questions into ChatGPT in another window. Interview Helpers runs as a transparent overlay: - Ctrl+1 — screenshot the question, get a structured answer in 2–4s - System Design mode — Mermaid diagrams + tradeoff analysis - Speaker mode — transcribes verbal theory questions ("explain TCP vs UDP") and serves a 30-second answer - Doesn't show up in screen-share or Zoom recordings Models: GPT-5 by default, Claude 4 for system design (better at tradeoffs). Free tier: 10 queries/day. Pro: $19/mo unlimited. Not here to argue the ethics — it's the same as having a senior engineer over your shoulder, except faster. Happy to take any question.
