Coding-test assist
Online coding tests — solution ideas and code in seconds.
Stuck on a coding-test question? Just screenshot it. AI reads the prompt, breaks down the solution steps, generates reference code in the right language, and annotates complexity — all side by side in three columns. Everything runs locally; the original question text is never sent out.

What it does for you
Step-by-step breakdown
Approach first, then code: from brute force to optimal, explaining the why.
Reference code in many languages
JS / TS / Python / Java / C++ / Go / Rust — pick your exam language.
Complexity annotation
Gives time / space complexity so you know whether the solution scales to the input size.
Approach / code / complexity, three columns
A three-column layout so you read the approach while copying the key code — no flipping back and forth.
Runs locally
Recognition runs locally — the original question text is never sent out, for peace of mind.
IN DEPTH · A closer look
Screenshot a question and get the approach, code and complexity all at once
OCR reads the question → breaks down the solution steps → generates reference code in multiple languages with complexity noted — approach and code in one go.
Screenshot recognition
Screenshot the question and the AI reads its intent automatically
Stuck on a coding-test question? Just press ⌘E to screenshot it. The AI auto-OCRs the question, understands the I/O and constraints, first explains what it read and the approach, then gives reference code in the right language — no need to retype the question.
- ⌘E one-tap screenshot, auto-OCR the question
- Understands the input / output / data-range constraints
- Explains the approach before the code, so you know why

Reference code in many languages
Pick your test language and get reference code and complexity right away
The AI generates reference code in the right language and marks time / space complexity so you know whether the solution clears the input size; approach, code and complexity sit side by side in three columns, so you can read the approach while transcribing the key implementation without flipping back and forth.
- JS / TS / Python / Java / C++ / Go / Rust and 7+ more
- Marks time / space complexity so you know it handles the input size
- Region or full-screen capture, up to 3 shots, paste images too
