🚀 Step-by-Step Guide

Using this script requires zero coding knowledge. Just follow these two simple phases!

Phase 1: Extract Your Games

First, we grab the list of games you own.

1. Log in to your library on either:
   • Epic Games Transaction History
   • Amazon Luna Collection
2. Open the Developer Console by pressing F12 on your keyboard (or Ctrl+Shift+I / Cmd+Option+I on Mac), and navigate to the Console tab.
3. Copy the script from Nvidia_GeForce_Library_Sync.js in this repository, paste it into the console, and press Enter.
4. The Auto-Sync Dashboard will instantly appear on your screen!
5. Click Extract. The script will automatically scrape your entire purchase history.
6. Once it finishes, click Copy Results To Clipboard.

Phase 2: Sync to GeForce NOW

Now, we automatically add those games to your NVIDIA account.

1. Log in to GeForce NOW in your browser at play.geforcenow.com.
2. Open the Developer Console (F12) again, paste the exact same script, and press Enter.
3. The Auto-Sync Dashboard will recognize you are on GeForce NOW. Paste your extracted games into the dark text box.
4. (Optional) Tweak settings in General Settings, such as increasing Sync Speed / Delay if your internet is slow.
5. Click ▶️ START SYNC.
6. 🛑 IMPORTANT: Take your hands off the mouse and keyboard! The script will take over the page, autonomously typing in the search bar and clicking the "Mark as Owned" buttons for you until every game is added.

❓ FAQ

Is this safe to use? Will I get banned?
This script only automates normal human clicks and typing inside your own browser window. It does not modify NVIDIA's backend servers. However, use at your own discretion.

The script is missing some of my games! Why?
Sometimes Epic Games names a game drastically differently than GeForce NOW (e.g., Game of the Year Edition vs standard edition). You can manually map title variations in the Custom Name Aliases box in Settings!

GeForce NOW is freezing or skipping games during sync!
NVIDIA's website enforces rate limits. Open General Settings in the UI and increase the Sync Speed / Delay slider to slow down execution.
