Tips for Better Results

  • Works on any platform where the problem is visible on screen: LeetCode, HackerRank, CoderPad, Codeforces, and more.
  • Make sure the full problem is visible before scanning. Full-screen the browser if needed.
  • Multiple monitors: StealthCoder captures your primary display. If you use multiple screens, make sure the problem is on your main monitor before scanning.
  • Click the problem window first to make sure it is focused, then trigger the scan.
  • Minimize sidebars, ads, and popups. A cleaner screen gives better results.
  • Use the overlay to guide your thinking, not to copy-paste directly. Type it out yourself and adapt the solution.

For system design interviews, switch to StealthDesign mode with Ctrl+Alt+Shift+M. It follows the standard FAANG format: Requirements, Estimation, Design, Deep Dive, and Trade-offs.
