Coding interview AI that reads your screen — and walks you to the optimal

Coding interview AI helpers are the make-or-break tool for live coding rounds at FAANG, top startups, and quant funds. The best coding interview AI reads the problem from your screen, identifies patterns, and walks you through the brute-force then optimal solution with full complexity analysis — all while you're typing. HelplyAI ships the most accurate coding-interview AI of 2026: it works on HackerRank, CoderPad, LeetCode, Karat, CodeSignal, and most internal company coding tools.

What separates HelplyAI from a generic LLM: the model is tuned for live coding interview style — concise, optimal, well-commented, with complexity and trade-offs explicit. It supports Python, JavaScript, TypeScript, Java, C++, Go, Rust, Swift, Kotlin, C#, Ruby, and SQL. Beyond solution generation, the AI spots bugs in your code as you type, suggests micro-optimizations, and primes you with follow-up questions the interviewer is likely to ask.

Pair this with our system design AI, behavioral AI, and the FAANG-tuned helper for full-loop coverage. For the platforms you're interviewing on, see Zoom guide, Google Meet guide, and Teams guide.
