COMPARISON
Interview Helpers vs LeetCode Premium
These two products solve different halves of the coding interview problem. LeetCode Premium is a practice library — locked problems, company-filtered question banks, peer mock rounds. Interview Helpers is a live AI copilot — screenshot a problem in the actual interview and get a streaming answer with commented C++ / Python / Java code and a system-design diagram if you need one.
You can absolutely use both. This page shows what each does well and when either alone is enough.
Interview Helpers wins 6 of 11 feature categories, LeetCode Premium wins 3, the rest are a tie. Updated August 28, 2026.

Which should you pick?
Pick LeetCode Premium if you want practice access
You need company-filtered problem banks, locked premium problems, and peer mock interviews. LeetCode Premium is optimized for the weeks leading up to the interview when you're grinding through problems solo.
Pick Interview Helpers if you want an interview-day copilot
You need something in the interview itself — a stealth overlay hidden from screen share that answers a screenshotted problem in seconds, drafts a system-design Mermaid diagram, and transcribes what the interviewer just said. LeetCode Premium is not intended for live use.
Use both if you want the strongest prep + live workflow
Grind with LeetCode Premium for pattern recognition, then keep Interview Helpers open in the live round for the specific problem you get asked (which is almost never one you drilled).
