About Luna - Technical Interview Copilot
Luna reads the live coding pad in front of you and puts a pasteable solution in a Chrome side panel. Technical challenges only. No microphone. No call audio.
Let me tell you something about coding interviews. Nobody gets the offer for what they studied last night. They get it for what they paste into the editor in the ninety seconds after the problem loads. You can know the answer cold and still sit there blinking at a blank function. Luna is the second pair of eyes that does not blink.
WHAT YOU GET
• Reads the pad — problem statement, starter code, constraints. Whatever is on the tab: HackerRank, LeetCode, CoderPad, or a take-home in the browser.
• Writes the solution — one suggested answer in the panel, formatted like an editor: colored keywords, intact indentation, ready to paste. Same function names as the starter. Same language as the pad.
• Brief — load your notes and limits once. Luna does not invent constraints that are not on the page.
• New answer on demand — the pad changed and you want a fresh take? Ctrl+Shift+Y (Cmd+Shift+Y on Mac). Done.
• No API key — you do not paste anything, you do not configure anything, you do not pay a second bill to a model provider. Luna's server handles it.
HOW TO USE IT
1. Open the coding challenge in a Chrome tab.
2. Click the Luna icon. The side panel opens next to the pad.
3. Luna reads the visible problem and starter and drops a solution in the panel.
4. Fill in Brief before the interview if you have notes you want honored.
5. Press Ctrl+Shift+Y when you want a new answer from the same page.
THE NUMBERS
The first 24 hours are on us. After that: $137 a year, or $250 once and you never think about it again. That fee covers Luna and the model usage. No add-ons, no meters, no surprise invoice. You know what a rejected offer costs you? More than $137.
PRIVACY (THE PART WE ACTUALLY TAKE SERIOUSLY)
This Chrome extension does not listen. No tab audio. No microphone. The visible text on the coding pad goes to Luna's server so it can write a suggestion. Your notes and license key stay on this computer. Nothing is sold. Nothing is used for anything except the next solution. Full policy: https://lunainterview.xyz/privacy/
PERMISSIONS
• "Read and change data on sites you visit" — Luna has to read the coding pad you have open, and those hosts are different for everyone, so it cannot be a fixed list. It reads the visible problem and starter so the suggestion matches the page.
• Storage — your brief, settings, trial start, and license key, saved locally.
SUPPORT

The only thing standing between you and the offer is a blank editor. Pick up the pen. Install Luna.
