The assessment locks your screen. The answer sits on top of it.

Timed online assessments run in forced full screen and log every tab switch, so looking anything up is off the table. Hover once: the AI reads the question already on your screen and puts the solution right next to it — the answer layer stays invisible to screen recording and screen sharing.

2. Two Sum

Given an array of integers nums and an integer target, return the indices of the two numbers that add up to target.

Each input has exactly one solution, and you may not use the same element twice.

Sample: nums = [2, 7, 11, 15], target = 9 → [0, 1]

Coding challenges

Approach, complexity, edge cases and a working implementation, laid out to drop straight into the browser IDE.

Take-home and system design

Long prompts get broken down into requirements, then into a structure you can actually submit.

Aptitude and personality tests

For SPI, Webtest and AI competency screens: reads what the item is really measuring and avoids the answers that quietly cost you points.

Multiple choice and domain quizzes

Answer first, then the reason the other options are wrong — so you stop second-guessing in the last minute.

Desktop app · v0.3.7

Bring AceRound to your desktop

Web, phone and desktop in sync. The desktop app is what sets it apart: an anti screen-capture answer layer for live interviews and online assessments.

Anti screen-capture

The answer layer lives only on your machine. It never reaches a screen share, a recording or a screenshot — interviewers and proctors see your screen exactly as it was.

Two-device isolation

Interview on your computer. Read answers on your phone. Two separate devices, nothing to spot on either screen.

Never steals focus or blocks input

Your keyboard and mouse stay in the assessment or the IDE. The answer just sits beside it.

Native Windows / macOS
