Coding copilot

The coding surface handles live algorithm rounds and technical screens across 18 programming languages.

Approach, code, and complexity in one response.

The workflow

  1. 1

    Snip the problem

    Press ⌘⌥⇧G and drag over the problem statement. This captures the region, attaches it, and sends it in one action.
  2. 2

    Read the approach first

    The response leads with a plain-English approach. That is the part you say out loud while you start typing.
  3. 3

    Work through the code

    Solutions come back in your configured language with syntax highlighting. Type it rather than pasting — you want to be able to explain each line.
  4. 4

    Have the complexity ready

    Time and space complexity come back with every solution, because it is the follow-up question every single time.

Languages

Set your language in the interview setup and it persists for the session.

Where it works

Anywhere. Because the surface reads your screen rather than integrating with an editor, the platform underneath is irrelevant — CoderPad, HackerRank, CodeSignal, LeetCode, Codility, HackerEarth, a shared Google Doc, or the interviewer's own tool.

Try Hints mode for take-homes
On an untimed take-home, switch the answer style to Hints. You get unblocked without handing in code you cannot defend in the follow-up review.
