Coding Test Copilot

AI reads the question on your screen and streams an answer into a private overlay — built for LeetCode-style OAs, HackerRank, Codility, CodeSignal, Karat, take-home assessments and any company coding round.

A private overlay, only on your machine

The desktop app draws the answer panel as an OS-level overlay that screen sharing, screen recording and screenshot tools cannot capture. Use it as your personal study aid — always follow each assessment platform’s terms and your employer or school’s policies.

Off the shared screen

The answer overlay stays out of screen shares, recordings and screenshots — only visible on your own display.

Coding-grade answers

Approach, complexity, edge cases and a ready-to-run snippet — tuned for LeetCode-style algorithms and OA problems.

Hover-to-solve, no tab switching

Hover the overlay button for ~1.2s and AI reads the visible question. No copying, no switching tabs out of the assessment.

Desktop app recommended for assessments

The web dashboard reviews your session history. For live assessments use the desktop app — that is where the off-screen overlay and screenshot-to-answer workflow live. Current build v0.2.5.
