}AI reads your screen, solves the problem, and streams back the solution.
Invisible to screen sharing. macOS content protection hides the panel from Zoom, Meet, Teams, and every recording tool. Your interviewer sees nothing.
Streaming AI responses. Solutions stream in real-time as the AI thinks. No waiting — read the approach while it's still generating.
Choose your model. GPT-4o, Claude, Gemini, DeepSeek, and more. Pick the model that works best for your interview type.
20+ stealth features, tested daily against every interview platform.
No app icon in the dock. No entry in Mission Control. The app doesn't exist.
macOS content protection makes the overlay invisible to all screen capture and recording.
The overlay passes clicks to whatever is behind it. No focus shifts, no flags.
Runs silently in the background. Nothing in Activity Monitor for anyone watching.
Set your own system prompt to match the role, language, or interview style.
Show and hide with one shortcut. The panel appears and disappears in milliseconds.
Screenshot the problem, solve it, hide the panel.
Screenshot the coding problem from any platform — LeetCode, HackerRank, CoderPad, a whiteboard.
AI analyzes the screenshot and streams back an optimized solution with time and space complexity.
Toggle the overlay on and off. Your interviewer never sees a thing.

Yes. We use macOS content protection (the same API used by DRM-protected video players) to make the overlay completely invisible to Zoom, Google Meet, Microsoft Teams, and every other screen recording or sharing tool.
You get 100 credits per day. Standard models (GPT-4o, Claude Sonnet, Gemini Pro, DeepSeek) cost 1 credit per query. Premium models (Claude Opus, GPT-o3) cost 5 credits per query. Credits reset at midnight UTC.
No. Phantom Coder hides from the dock, Mission Control, and screen capture. It runs as an invisible overlay that passes clicks through to whatever is behind it. There is no visible trace on your system.
Phantom Coder works with any interview platform — LeetCode, HackerRank, CoderPad, CodeSignal, or even a shared Google Doc. Just screenshot the problem and the AI analyzes it.
GPT-4o, GPT-4o Mini, Claude Sonnet 4, Claude 3.5 Haiku, Gemini 2.5 Flash, and DeepSeek R1. You can switch models per query depending on the problem type.
Currently macOS only (13+). The content protection and stealth features rely on macOS-specific APIs. Windows support is on the roadmap.
