Desktop and mobile AI copilot that feeds live answers during coding and system design interviews
The desktop app is designed to remain hidden from Zoom and browser-based screen recording, with moveable overlays and no visible taskbar presence.
Capture any window containing a coding problem and receive a complete solution with syntax highlighting, approach notes and complexity analysis.
Transcribes both your voice and the interviewer's audio so spoken system design and behavioral questions can be answered in the moment.
Pair the desktop app with a phone for remote screenshots, prompts and answers, or use the browser-based mobile mode with no installation.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
