Frequently Asked Questions

Everything you need to know about the assistant, hardware isolation, and billing.

How does the hardware screen recording exclusion work? ▼
ProfiTestAI uses built-in operating system display protections. When external applications (such as OBS Studio, Zoom, Microsoft Teams, or Loom) capture your screen or window, the assistant overlay is automatically omitted from the video stream, keeping your recordings clean.
What exam and quiz platforms are supported? ▼
ProfiTestAI is universal because it reads questions visually directly from your screen. It works seamlessly with any desktop browser (Chrome, Safari, Firefox), practice test portals (MeasureUp, Whizlabs, Tutorial Dojo, LeetCode, HackerRank), PDFs, desktop test engines, and university LMS systems (Canvas, Moodle, Blackboard).
How do I activate the assistant during my practice tests? ▼
Simply launch the application and open your practice exam. Press the global shortcut Cmd + Shift + S (on macOS) or Ctrl + Shift + S (on Windows) to adjust the capture area (full screen, specific window, or selected region) and start. The assistant analyzes questions as they appear without stealing keyboard focus.
Can I cancel my subscription? ▼
Yes. You can cancel your monthly subscription at any time with a single click via the link in your receipt email or directly inside the app. Once cancelled, your access remains active until the end of the paid billing period, and no further charges will occur.
What languages are supported for questions? ▼
Both Russian and English are fully supported with specialized prompt isolation. You can toggle the active language instantly in the top corner of the assistant window. Additional languages are in preparation.
