Get detailed, educational breakdowns of how code works. Perfect for learning, code reviews, and understanding unfamiliar codebases.
The Explain tool analyzes your code and produces a comprehensive, educational explanation that covers:
Line-by-line or block-by-block explanation of what the code does, how it works, and why it's written that way.
Big-O time and space complexity analysis, identifying potential performance bottlenecks and scalability concerns.
Identification of edge cases, boundary conditions, and potential failure modes that the code handles (or should handle).
Explanation of programming concepts, patterns, and language features used in the code, great for learning.
Click the Explain button in the toolbar (blue icon) or press Cmd/Ctrl + 1.
Enter the code you want to understand in the left panel. The language will be auto-detected, or you can select it manually.
Click the action button to start the analysis. ARKAbrain will route your request to the optimal model based on code complexity.
Read through the structured explanation in the Result tab. Use the table of contents to jump to specific sections.
Here's an example of code you might want explained:
function binarySearch(arr, target) {
let left = 0;
let right = arr.length - 1;
while (left <= right) {
const mid = Math.floor((left + right) / 2);
if (arr[mid] === target) {
return mid;
}
if (arr[mid] < target) {
left = mid + 1;
} else {
right = mid - 1;
}
}
return -1;
}The Explain tool would provide:
Focus on Specific Code
For best results, submit focused code snippets (functions, classes, or modules) rather than entire files. This produces more detailed and relevant explanations.
Include Context
If your code uses custom types, interfaces, or imports from other files, include them in your submission for a more complete explanation.
