What LeetCode Assessments Track
Regular LeetCode practice isn't proctored, but company online assessments (OAs) hosted on LeetCode add monitoring the employer reviews:
- Full-screen & tab-switch logging — OAs record when you leave the assessment tab
- Paste detection — flags large code blocks pasted into the editor
- Time tracking — records time per problem and total session time
- Optional webcam / screen proctoring — some company OAs enable camera monitoring
- Copy-restricted problem text — some OAs disable selecting the problem statement
Why Alt-Tab and Browser Extensions Fail on LeetCode
On a company OA, alt-tabbing to look up the approach is logged and reported to the recruiter, and pasting a full solution triggers paste detection. UFOlee screenshots the locked problem statement (so copy-restriction doesn't matter), keeps the AI in an overlay so you never switch tabs, and types the solution with hardware keystrokes so there's no paste event.
How UFOlee Works with LeetCode
For a proctored OA, screenshot the problem, solve with your AI, and auto-type the answer:
- Launch UFOlee and log into your preferred AI (ChatGPT, Claude, Gemini) before starting the test
- Open your LeetCode assessment — UFOlee runs invisibly in the background
- Press Ctrl+Shift+S to reveal UFOlee's stealth browser overlay on top of LeetCode
- Press Ctrl+Shift+A to screenshot the question and automatically attach it to your AI chat
- Read the AI-generated solution, then highlight the answer or code you need
- Press Ctrl+Shift+F — UFOlee auto-types it into LeetCode using native hardware keystrokes
- Press Ctrl+Shift+S to hide UFOlee and review your work
