LeetPilot

LeetPilot is a hidden macOS coding assistant controlled from a phone or second device. It captures screen and call audio remotely, runs code in a sandbox, and returns answers and diagrams in a browser. Free tier and a $49 per month Pro plan.

LeetPilot is an AI coding assistant built around one design choice: nothing about it appears on the computer being used. A small desktop app is installed once, hidden, and from then on it runs with no window, no dock icon and no tray entry. Instead of keyboard shortcuts or an overlay, the user signs in to leetpilot.com on a phone, tablet or second laptop and triggers every action from there. The vendor says it has 1,728 students and engineers as users. In practice the flow has three parts. A tap on the second device makes the computer capture its own screen, and several shots can be stacked for a question that does not fit on one screen. A listening mode transcribes both sides of a call live, so follow-up questions have context. The answers then appear in the browser on the helper device. Because LeetPilot reads whatever is on screen, it works with web pages, shared code editors or plain text files rather than integrating with specific sites. Several helper devices can stay in sync at once. Answers for coding questions are checked in an inbuilt code runner before they are shown. The runner covers Python, Java, C, C++, C#, Go, Rust, Kotlin, Swift, Scala, Dart, Ruby, JavaScript, TypeScript and SQL, and the demo on the homepage shows it catching a bug and rerunning a fix. System design, object-oriented design and schema questions come with a diagram. Behavioural and general questions are also supported, and transcription covers major languages including English, Chinese, Japanese, Korean, French, German, Spanish and Portuguese. The product targets students and engineers preparing for or sitting technical interviews and timed assessments. Its main point of difference from other assistants is the concealment model: it rejects global shortcuts and overlay windows entirely. That same feature is the biggest consideration for buyers, since employers and assessment platforms commonly prohibit outside assistance, so use may violate the rules of the session. Compared with visible copilots and general chat tools, LeetPilot trades convenience for a remote, two device workflow, and the homepage lists a free tier and a single paid Pro plan.
