Coding interview copilot
A coding interview copilot for live coding rounds and OAs
Screenshot a LeetCode-style problem and Interview Solver returns the approach, time and space complexity, and working code in the language you are using. It runs as a desktop app, so it keeps working while your coding pad is shared.
Built around how coding rounds actually run
Coding rounds have a few predictable shapes: a shared editor like CoderPad with an interviewer watching, a timed online assessment on HackerRank or CodeSignal, or a take-home problem set. In each one the problem is on your screen, so a screenshot is the fastest way to bring it in.
Interview Solver answers the way you would be expected to explain it: first the idea and why it works, then the complexity, then the code. That order makes it easier to talk through the solution instead of pasting something you cannot explain.
Some HackerRank interviews run inside a downloadable tool that logs keyboard shortcuts. For those, Companion mode lets you trigger screenshots and prompts from your phone so nothing is pressed on the interview machine.
From problem to answer
Step 1
Capture the problem
Press the screenshot hotkey while the problem is visible. The copilot reads the prompt, examples and constraints from the image.
Step 2
Read the approach first
The answer opens with the pattern (two pointers, BFS, dynamic programming and so on) and why it fits the constraints.
Step 3
Check complexity and edge cases
Each answer states time and space complexity and calls out the edge cases an interviewer is likely to ask about.
Step 4
Type the code yourself
Code arrives with syntax highlighting in your language. Ask follow-ups like “optimize for memory” or “now handle duplicates” and the context carries over.
Made for coding interviews
Trained on the LeetCode question bank
Answers draw on the full set of LeetCode problems, so common company questions come back with the known optimal approach.
Works on the major coding platforms
HackerRank, CodeSignal, CoderPad, LeetCode and other browser-based editors, during live rounds and timed assessments.
Global hotkeys
Capture, scroll and ask follow-ups without clicking away from the editor or moving focus to another window.
Companion remote controls
When a downloadable interview tool logs hotkeys, trigger screenshots and prompts from your phone instead.
Multi-monitor and transparency controls
Place the overlay where your eyes already are and set its transparency so reading it looks like reading your code.
Practice on real company problems
Our practice pages and company question lists cover the problems that come up most, so you can rehearse the workflow before the real round.

Coding Interview Copilot FAQ
What is a coding interview copilot?+
A coding interview copilot is an AI tool that helps during a live coding round or online assessment. You give it the problem, usually as a screenshot, and it returns an approach, the complexity and code. Interview Solver does this from a desktop app that stays out of your screen share.
Does it work on HackerRank and CodeSignal?+
Yes. Interview Solver captures the problem from your screen, so it works with HackerRank, CodeSignal, CoderPad, LeetCode and other browser-based editors. For HackerRank interviews that run in a downloadable tool that logs hotkeys, use Companion mode to trigger captures from your phone.
Which programming languages are supported?+
Answers can be written in any mainstream interview language, including Python, Java, C++, JavaScript, TypeScript, Go and C#. Ask for a different language at any point and the copilot rewrites the solution.
Will I be able to explain the solution?+
Each answer leads with the idea and the reasoning before the code, and states the complexity and edge cases, so you have what you need to talk through it. You can also ask the copilot to walk through an example input step by step.
How much does it cost?+
Monthly is $59/mo and Interview Cycle is $149 for three months. The desktop app includes 10 free messages, and Interview Solver Mobile has a one-time trial of 10 minutes and 10 answers, with no credit card required.
Try it before your next interview
Install the desktop app or open Interview Solver Mobile, then run a practice problem to see the workflow.
