Share your screen. They see nothing.
GhostApp is excluded from Zoom, Teams, Meet, screenshots, and recordings — while you get every frontier model in under 100ms.
Read the WhitepaperInvisible on your desktop
No Dock. No taskbar. No Alt Tab. Activity Monitor and Task Manager do not get a clean name to hunt.
Invisible on their screen share
Full screen share on Zoom, Teams, or Meet still shows a clean desktop. Overlay, menus, and popups are excluded at the compositor.
Type without leaving the meeting
The coding tab stays focused. Keystrokes never hit the browser DOM. Built for HackerRank, CoderPad, and CodeSignal.
Click through like it is not there
Focus Mode lets clicks pass to the app underneath. Scroll the overlay. The interviewer sees only the problem set.
One shortcut. You never existed.
Instant hide, click through, stop capture, and wipe clipboard. Auto panic if analysis tools probe the process.
A new identity every launch
Randomized binary name, isolated temp path, spoofed parent, burned on exit. Static scanners get nothing to fingerprint.
Hardened at runtime. Private on the wire.
Anti debug, anti hook, and API integrity checks. HTTP, HTTPS, SOCKS5, and Tor for AI traffic.
All leading LLMs. One unified interface.
Instantly switch providers in real time with zero configuration.

Advanced Models — We integrate frontier models within 48 hours of release.
Browser extensions get caught.
GhostApp does not.
True Invisibility
Share your entire screen on Zoom, Teams, or Meet. They see a clean desktop. GhostApp stays out of the capture — overlay, menus, and popups included.
Auto Screen Reading
Instantly detects coding questions from your IDE or browser. Zero copy paste. Zero Alt Tab.
Audio Interception
Direct audio taps capture speaker audio in real time, drafting contextual answers as they're asked.
Not Just LeetCode
STAR behavioral answers, system design diagrams, and architecture deep dives — for every round.
TsarChat: Native First Architecture (Swift / C++)
Unlike hybrid wrappers (e.g., Electron or Tauri) that depend on heavyweight, sandboxed web views, TsarChat runs through direct OS level integration. This approach eliminates unnecessary abstraction layers, enabling true system level control and near zero latency execution.
Metal Level Performance
Built with Swift (macOS) and C++ (Windows) to achieve sub millisecond response times. Leverages Metal and DirectComposition for hardware accelerated rendering, delivering minimal CPU overhead and highly responsive UI performance.
Stealth and Anti Detection
Native capture exclusion on Windows and macOS — Zoom, Teams, and Meet receive zero pixels. GhostApp stays off the Dock, out of Alt Tab, and off the recording.
Hardened Security
Employs a local first, zero knowledge architecture with AES 256 GCM encryption. The binary is fortified with ASLR and DEP protections to mitigate risks such as memory inspection, hooking, and exploitation.

- Visible on every shareElectron apps render like any other window. Zoom, Teams, and Meet capture every pixel — including the copilot you thought was hidden.
- A process they can nameHelper names like CoderHelper.exe sit in Task Manager in plain sight. One glance and the overlay is blown.
- Browser heavy and slowChromium runtimes eat 500MB+ RAM and add 200ms+ of JS bridge lag to every keystroke when seconds count.

- Native speed, not a wrapperGPU composited overlay with under 50ms latency and about 60 to 140MB RAM. Ten times faster than Electron copilots.

TsarChat: powered by the GhostApp stealth engine.
Hit hide. In three seconds, you never existed.
Panic Hide cloaks the window, enables click through, stops capture, and wipes the clipboard — then auto triggers if analysis tools probe the process. Start the 30 day trial and test it on a dummy Zoom share.
From Question to Answer in 3 Steps
Launch & Vanish
Open GhostApp before your meeting. It instantly cloaks itself — designed to be undetectable to common screen-sharing and recording tools.
Auto-Detect Everything
GhostApp reads your screen and captures audio in real-time. It detects coding problems, behavioral questions, and system design prompts automatically.
Deliver & Impress
Get solutions, explanations, and talking points from the best LLM for each question. Deliver answers naturally while GhostApp stays completely hidden.
Works with everything interviewers throw at you.
Tested weekly against every major platform. When one of them ships an update, we patch within 48 hours.
