Coding Test Copilot
Online assessments are the part of hiring where you are alone with a timer. The Coding Test Copilot reads the question off your screen and streams a solution into an overlay beside it — no tab switching, no window juggling, and nothing that shows up on a shared screen.
Requires the desktop client. The overlay and the screen capture are native capabilities; the browser cannot provide them. See Desktop App.
What It Handles
- Coding challenges — LeetCode-style problems, algorithm rounds, company-specific judges
- Take-homes and system design — longer, multi-part problems
- Multiple choice and domain quizzes — single answer, multi-answer, true/false, fill-in-the-blank, SQL
- Aptitude and personality assessments — including the long consistency-checked psychometric batteries
Works on LeetCode, HackerRank, Codility, CodeSignal, Karat, CoderPad, HackerEarth, take-home assignments, and any in-house assessment platform — because it reads the screen rather than integrating with the site.
How It Works
- Open the desktop client and start a Coding Test session.
- Open your assessment as normal, in whatever browser or IDE the employer gave you.
- Capture the question — press
Ctrl/⌘ + Shift + S, or hover the overlay trigger. - Read the answer as it streams into the overlay next to the problem.
- Follow up if you need to: ask for a different approach, an optimisation, or a review of the code you actually typed.
Your keyboard and mouse never leave the assessment. The overlay is click-through and does not take focus, so the timer, the editor and the proctor's page all keep behaving normally. The overlay is excluded from screen sharing, window recording and screenshots.
Two Modes
| Quick | Programming | |
|---|---|---|
| Built for | Multiple choice, short questions, quizzes, aptitude tests | Coding problems, system design, long take-homes |
| Speed | Faster | Slower, more capable |
| Pages per capture | Up to 4 | Up to 6 |
| Billed | Per screenshot | Per question |
Quick mode is the default. Switch to Programming mode when the question is a real engineering problem rather than a lookup.
Follow-Ups
After a solution arrives, you can push it further:
- Explain the approach — get the reasoning, so you can defend it in the follow-up interview.
- Alternate solution — a different algorithm or structure.
- Optimize the code — tighter complexity or cleaner structure.
- Check the code I typed — paste or capture what you actually wrote and the AI reviews it line by line against the problem.
- Partial pass — rewrites the solution into one that compiles and gets the main path right while leaving one reasonable edge case out. Useful when a perfect score would look out of character.
Customising the Answers
Set these once and they apply for the whole session:
- Answer language — the natural language the AI explains in. Defaults to your interface language, not the language of the question, so you can read explanations in your own language while solving an English problem.
- Programming language — pin it, or let the AI follow whatever the assessment expects.
- Code style — Standard, Readable, Concise, or Performance-oriented.
- Custom requirements — free text, e.g. "no external libraries", "add brief comments", "match the starter template's signature".
The same preferences drive screenshot solving during live interviews, so you configure them once.
Personality and Aptitude Assessments
Psychometric batteries run 60–120 questions and you will capture them a screen at a time. AceRound builds a consistent profile on the first capture — a role-appropriate trait slant plus a couple of harmless weaknesses — and holds it for the rest of the session, so the same trait probed twice from opposite directions still gets a consistent answer.
Your History
Every solved question is saved under My assessment history in the Coding Test Copilot page — the question, the solution and the follow-ups. Delete any record at any time.
What It Costs You
Quick mode is billed per screenshot; Programming mode per question. On an active Pass, coding-test solving is unlimited. See the FAQ for how balances are consumed.
Tips
- Install and sign in before assessment day; some assessments start a timer the moment you open the link.
- Capture the whole question, including constraints and examples — cropped screenshots give worse answers.
- Type the solution yourself rather than pasting it. Many platforms flag paste events, and some record keystroke timing.
- Read the approach before you write. If you cannot explain it, the follow-up interview will be the problem, not the test.
