How it works

Pick your path

Choose role, language, and a real interview‑style problem.

Talk while you code

Explain your approach out loud and iterate in the editor.

Improve with feedback

Instant suggestions grounded in your code and test results.

Context‑aware engine

Feedback grounded in your code — not screenshots

The coach understands what changed, what you tried, and what passed. That means specific, actionable guidance in near real time.

Code understanding

function canAttendMeetings(intervals) {
  intervals.sort((a,b)=>a[0]-b[0]);
  return intervals.every((cur,i)=>
    i===0 || cur[0] >= intervals[i-1][1]
  );
}

Inline suggestions

// Hint: sort by start time
// and compare to previous end

Ask for a hint to get small, targeted nudge—no full solutions.
