A powerful desktop application that runs as an invisible overlay, capturing screen regions, transcribing audio, and streaming AI-powered solutions. Built specifically for ultimate stealth — it remains completely invisible to screen share platforms like Zoom, Google Meet, OBS, and MS Teams.
- Screen-Share Proof: Utilizes hardware-level window exclusion (
setContentProtection(true)) so the app never shows up on screen shares or recordings. - Click-Through Transparency: The UI lets your mouse clicks pass through to underlying applications, ensuring zero interruption to your regular workflow or IDE usage.
- Taskbar Hidden: No icons in the taskbar; operates purely as a background utility with a discrete system tray icon.
- Real-time Audio Processing: Transcribe live interviews, meetings, and technical discussions as they happen.
- Automated Context: Feeds the spoken conversation context directly to the AI to understand exactly what is being asked and generate highly relevant coding solutions dynamically.
- Region Selector UI: Drag a simple crosshair over any coding problem, browser window, or terminal to capture the specific context.
- Real-time Solution Streaming: Screenshots are passed to your chosen LLM Vision model, streaming back high-quality, formatted code solutions in real-time.
- Ask Follow-ups: Seamlessly type custom questions and prompts directly in the invisible interface while keeping it hidden from viewers.
- Context-Aware Memory: The AI remembers the ongoing session to provide continuous, context-aware assistance.
- Connect your own API keys for ultimate privacy and control.
- Supported providers include: Google Gemini (default, excellent vision features), OpenAI, Anthropic, and Groq (for blazing-fast text responses).
- Encrypted Storage: API keys, user settings, and session history are securely stored and encrypted locally via
electron-store.
- Dark Glassmorphism UX: Sleek, modern, and non-distracting visual design.
- Global Hotkeys: Trigger captures, clear the screen, or hide the app instantly from anywhere.
