Direct answer

If you want help during a live interview, choose a tool with a private overlay that stays invisible on screen share, and workflows you can practice ahead of time. Two vendors publish real-time assistants with hidden windows: Beyz AI’s Invisible Desktop overlay and FinalRound AI’s Interview CoPilot. Beyz emphasizes a keyboard‑controlled overlay and prep tools (cheat sheets, coding assistant). FinalRound AI emphasizes live suggested answers, Stealth Mode, practice/debrief loops, and on‑screen reading for problems. Pick by how you work: overlay controls and prep assets (Beyz) versus suggested‑answer streams plus automatic debriefs (FinalRound).
