SYSTEM-WIDE STEALTH
Invisible Across Every Checkpoint. HintLens is built to be the most complete invisible AI for interviews — hidden across taskbars, process monitors, and window switchers from the moment you open it.
Invisible on Windows Taskbar
The HintLens assistant leaves absolutely no trace on your taskbar. It operates strictly as a background utility, ensuring that no suspicious icons appear next to the applications you share during an interview.
Invisible in Task Manager
The process is intelligently aliased to blend seamlessly with routine Windows background services. When viewed in the Task Manager, it remains entirely indistinguishable from standard system operations.
Invisible on Alt + Tab
Pressing Alt + Tab will never reveal the HintLens overlay. There are no preview tiles or highlighted windows, allowing you to multitask securely without accidental exposure.
Undetectable Hotkey Registration
Hotkeys are registered at the deepest operating system level using global Windows shortcuts. Keystrokes never propagate to your web browser or online assessment tools, making them completely invisible to screen-sharing software and proctoring systems.

FEATURES
The Ultimate Stealth Desktop App
The HintLens desktop client unleashes the full power of our AI natively on your machine. Engineered for zero detectability, it provides continuous, real-time interview support that remains completely imperceptible to proctors, observers, and screen-sharing applications.
Unmatched Stealth Mode
Operate entirely under the radar. Our proprietary graphics rendering ensures that the overlay is strictly invisible to all screen-sharing software and recording tools.
Dynamic Transparency
Command your visual space. Instantly dial the UI opacity up for clear reading, or fade it into a subtle ghost-overlay with a quick hotkey.
Precision Area Selection
Focus the AI on exactly what matters. Swiftly drag to capture specific code editors, terminal outputs, or complex question blocks in milliseconds.
Native Audio Capture
Flawless, real-time transcription. HintLens intercepts internal meeting audio directly from your system, guaranteeing zero-latency AI processing.
REAL-TIME ASSIST
Live answers, the exact moment you need them
Never lose your train of thought during critical interviews or high-stakes meetings. HintLens continuously analyzes the conversation and surfaces contextually perfect responses in milliseconds — eliminating hesitation entirely.
