Completely Undetectable.
We Guarantee It.
Invisible to Screen Share
Uses macOS native content protection. Your overlay is completely invisible to Zoom, Google Meet, Teams, and all recording software.
Hidden from Activity Monitor
Disguised as CoreServicesUIAgent — a legitimate macOS system process. No one will know it's running.
No Dock Icon, No Trace
Runs silently in the background. Nothing appears in your Dock, no window in Mission Control, no trace anywhere.
Click-Through Overlay
The overlay doesn't intercept mouse clicks. You interact with your IDE and browser normally — AI floats on top.
All platforms verified undetectable

Dream Offer
Download & Install
Download the DMG from this page. Open it and drag the app to your Applications folder. That's it — no installer, no signup.
Grant Screen Recording
On first launch, macOS asks for Screen Recording permission. Go to System Settings → Privacy & Security → Screen Recording and enable it. This is required for the capture feature.
Windows: Allow SmartScreen
Windows only: You may see a "Windows protected your PC" warning. This is normal for new apps. Click More info → Run anyway. On macOS, grant Screen Recording permission when prompted.
Try It — Open a LeetCode Problem
Open a problem like Two Sum or Merge K Sorted Lists. Position the overlay next to the problem. Press Cmd+Alt+P — the AI reads the problem from your screen and streams the solution in real-time.
Set Up Your Window
In Interactive mode, resize and position the overlay. Snap to screen edges with Cmd+Alt+1–9. Adjust opacity with Cmd+Alt+[ / ]. Your window size is remembered automatically.
Switch to Passthrough for Interviews
Press Cmd+Alt+M to enter Passthrough mode. Your mouse clicks go through the overlay to apps behind it — your cursor movement looks completely natural to the interviewer. All keyboard shortcuts still work.
Interactive vs Passthrough
Interactive Mode
Use for: Setup, practice, and reading solutions at your own pace.
You can click buttons, scroll through responses, resize the window, and access Settings. The overlay is fully interactive and focusable.
Best for: solo practice on LeetCode, adjusting settings before an interview, browsing the How to Use guide.
Passthrough Mode
Always use during live interviews. Mouse clicks pass through the overlay to your IDE and browser beneath it.
Your cursor movement looks completely natural — the interviewer sees normal mouse behavior. The overlay won't steal focus or interfere with typing.
All shortcuts (Cmd+Alt+P to capture, ↑↓ to scroll) work in both modes.
Pro tip: Set up your window position, size, and opacity in Interactive mode before the interview. Then press Cmd+Alt+M to switch to Passthrough. You're ready.

Questions? Answered.
Can my interviewer detect this?
No. Steal AI uses the macOS setContentProtection API which makes the overlay window completely invisible to all screen capture and recording software, including Zoom, Google Meet, Microsoft Teams, OBS, and QuickTime. Your interviewer sees nothing.
Does it show up in Activity Monitor?
It appears as CoreServicesUIAgent — a real macOS system process name. Even if someone checks Activity Monitor, it looks like a normal part of the operating system.
Is my data safe?
Yes. Screenshots are processed in real-time through our encrypted proxy and immediately discarded. We never store your interview content, screenshots, or AI responses on any server.
Is it really free?
Yes. Download and get 50 free AI calls with no credit card required. Your 50 free calls reset every month — that's enough for several practice sessions or a real interview. Upgrade to Pro or Premium only if you need more.
What happens when I run out of calls?
For free users, your 50 calls reset every month. For Pro and Premium subscribers, your quota resets at the start of each billing cycle. You can always see your remaining balance in the app settings.
Can I cancel anytime?
Absolutely. Cancel your subscription instantly through your account dashboard. No hoops, no retention flows, no questions asked.
How is this different from ChatGPT?
ChatGPT requires tab-switching, copy-pasting, and is visible on screen share. Steal AI is an invisible overlay — it reads your screen automatically, streams answers in real-time, and your interviewer never sees a thing. Purpose-built for live coding interviews.
Which coding problems does it handle?
Arrays, strings, trees, graphs, dynamic programming, system design, OOD, SQL — any problem you can screenshot. It analyzes the visual content and returns a structured solution with algorithm explanation, time/space complexity, and clean code.
